Applications: Sputtering is commonly used to apply reflective coatings on glass, produce thin films for solar cells, and fabricate layers on semiconductor wafers. Its ability to coat complex shapes and features makes it invaluable in manufacturing electronics and display panels.

The first type of guide is a straight edge of some type. You can use anything that has at least about 1/4″, or so, of thickness and it needs to actually be straight. The edge of the the circular saw base should ride along the straight edge without sliding over the top of it.

Common Materials: Commonly used materials in cathodic arc deposition include titanium, chromium, and zirconium, which are ideal for creating hard, wear-resistant coatings.

The first thing you want to do is get the saw in place. You will have the most trouble starting the cut accurately because you don’t have anything to reference the base on. The saw could be angled or tilted and you don’t realize it.

A few months ago, I made a video showing you how to make a straight cut with the jigsaw. But, the circular saw is a tool you will use much more than the jigsaw, so I want to show you how to make nice, straight cuts with the circular saw with or without a guide.

Process Description: The process involves striking an electric arc directly onto a material source or “target”, which rapidly heats and vaporizes the material in a highly ionized plasma form. This plasma is then condensed onto the substrate to form a coating. The high degree of ionization (ranging from 30% to 100%) enhances the film’s mechanical properties and adhesion to the substrate.

In conclusion, Physical Vapor Deposition stands as a cornerstone of advanced manufacturing, continually evolving to meet the challenges of a rapidly changing technological landscape. For those interested in further exploring this field, additional resources and links provided in this article offer avenues for deeper understanding and engagement with the latest in PVD research and applications.

The blade guard on the saw is designed to be pushed up by the workpiece as you push through the cut, but this will result in you pushing hard into the cut and twisting the saw one way or another. Instead I pull the guard up just enough to clear the workpiece. Then, I can let go of it after the guard is on the workpiece or just hold it through the cut.

Applications: Cathodic arc deposition is predominantly used for tool coatings in industries requiring high durability and resistance to wear, such as cutting tools and dies. It is also used for decorative coatings in the automotive and architectural sectors due to the excellent finish and color consistency it provides.

The first one is modeled after saw guides for sale on the market and it’s specific to your saw. The wonderful thing about this is that you simply measure and mark for the piece you want and put the guide in place right on those marks and clamp it down. That easy. The saw rides up against the fence and cuts a perfectly straight line.

Types of Materials: Metals, ceramics, plastics, and composites can all be plasma sprayed, making this technique suitable for a wide range of applications. The choice of material depends on the desired properties of the coating, such as thermal resistance, electrical conductivity, or biocompatibility.

When you start the saw the blade should never be touching the workpiece. Back it up about 1/2″, start the saw, and then slowly push it into the cut, erring on the waste side of your notch, and then ease the blade over to the line. Keep even pressure throughout and keep the saw steady.

Key Applications: Vacuum evaporation is integral in the fabrication of microelectronics, where it is used to form contacts and interconnects in devices.

After making the marks for the dimension of wood you want to keep, add the width of the saw base and make that mark at each end. Clamp the straight edge in place, right on those lines, and put the saw in position to make sure it’s going to cut where I want it to.

Process Description: Ion plating involves evaporating the coating material, typically metals or alloys, in a vacuum chamber and then ionizing these vaporized particles using a plasma source. An electric field accelerates these ions towards the substrate, where they condense to form a thin film. This ion bombardment not only deposits the material but also increases the density and adhesion of the film through a process called “ion etching” that occurs simultaneously.

Sputtering deposition is a highly versatile PVD method that involves ejecting material from a target (or “sputter target“) through bombardment with energetic particles, usually ions, which then deposit onto a substrate to form a thin film. This method can be adapted to deposit a wide range of materials including metals, ceramics, and plastics.

The last thing I’ll to mention could be the difference between an OK cut and one that could almost pass for square. Use a scrap piece of wood with a square edge and place it flat on the workpiece. Once the saw is in place push your makeshift fence up against the saw base and apply light pressure toward the saw to keep it steady during the cut.

Industrial Uses: Plasma spraying is extensively used in the aerospace industry for thermal barrier coatings on turbine blades and engine components, which helps in withstanding high temperatures and reducing wear. It is also popular in the biomedical field for coating medical implants to improve their integration with bone and other tissues.

Process Description: In PLD, a laser beam is directed at the target material in a vacuum chamber. The intense energy of the laser pulse vaporizes the surface of the target into a plasma plume, which then deposits on the substrate. The process allows for the deposition of materials with complex stoichiometries and high melting points.

Now, you need to measure the distance between the edge of the circular saw base and the blade. When you measure make sure you measure to the edge of a blade tooth as that will be the edge of the cut. You can write that measurement on the top of the base with a paint marker so you don’t forget it.

This technique takes time and it can be inaccurate with so many measurements involved, so let’s talk about a couple of different ways to make a track that fits your circular saw.

Start with a 1×2 and drill 3/4″ holes side-by-side to allow for a spring clamp to fit. Not every workpiece will be the same width, so drill the notches wherever you need them to be for clamping surface. I also find it helpful to completely notch each end of the 1×2 to give me more area to clamp on the ends.

It’s true. I can’t use a tape measure without making a mess. And, I make mistakes. I don’t screw up near as much as I used to, but I have been known to rebuild entire portions of a project.

If you have to stop and reposition yourself, make sure you keep the saw completely still as it winds down and then carefully move into the next position so that you don’t bump the saw. Carefully back it up about 1/2″, start the drill, and then finish the cut. This isn’t the ideal way, but sometimes you aren’t able to make a long cut in one motion.

Cathodic arc deposition, often referred to as arc PVD, is a method characterized by its ability to evaporate target materials through the use of an electric arc. This method excels in producing highly ionized vapor, which results in coatings that are extremely dense and adherent.

I’ll start with my preferred way to make straight cuts with the circular saw and it also happens to be the easiest. But, if you find yourself without a guide I also want to show you how to make the straightest cut possible by cutting freehand and I’ve got a technique that I’ve never seen anyone else use, so stick around for that.

This takes an extra few seconds, but it gives you a flawless way to start your cut without missing the mark and cutting the corner of your workpiece. It also prevents tear out on that corner.

As we look to the future, the role of PVD is set to expand further. The ongoing development of hybrid techniques, greater automation, and nanostructured coatings are poised to enhance the efficiency and effectiveness of PVD methods. Moreover, the increasing focus on sustainability and the rising demand in emerging markets highlight the growing importance of PVD technologies globally.

Just like that we’ve got a makeshift saw guide that you can make on the spot, just about anywhere, as long as you have some scrap wood.

You know how to read the big numbers on a measuring tape, but do you know everything the measuring tape does and what all the markings mean?

Benefits: This technique offers excellent control over film composition and thickness, making it possible to achieve specific electrical, optical, and mechanical properties. Sputtering can also cover large areas uniformly and is scalable from small research samples to large industrial components.

You also want to account for the thickness of the blade or what’s called the kerf. If you try and cut down the middle of a line, you’re going to cut into the piece you want to keep and its measurement will be off. Line your blade up so that the outside of the tooth touches your line on the waste side; the side you’re cutting away.

Applications: EBPVD is widely used in the aerospace industry for coating turbine blades with thermal barrier coatings to enhance their durability and performance at high temperatures. It is also used in the semiconductor industry for depositing films with high electrical conductivity and in optical applications for anti-reflective coatings.

Process Description: In EBPVD, an intense beam of electrons is focused on the target material, causing it to heat and eventually vaporize. The vaporized material then travels across the vacuum chamber and condenses on the substrate, forming a thin film. The process is conducted under high vacuum conditions, which minimizes contamination and allows for the deposition of very pure materials.

Process Description: In plasma spraying, a material in powder form is fed into a plasma torch, where it is rapidly heated to a molten or semi-molten state. The high-velocity plasma jet then propels these particles onto a substrate, where they flatten and rapidly cool to form a dense, strong coating. The process is conducted in a controlled atmosphere or under vacuum to prevent oxidation and ensure high-quality coatings.

Advantages: One of the primary advantages of plasma spray coating is its high deposition rates, which make it ideal for covering large areas quickly. The process also allows for the deposition of very thick coatings, which is beneficial for applications requiring robust wear and corrosion protection.
