HEF patented PEMS is a magnetron sputtering process enhanced by an auxiliary plasma source. This triode system allows independent control of material flux, ion energy and substrate bias. PEMS can provide a multitude of high performance coatings with application customized hardness, density and toughness.

Material is usually extracted from a high-purity solid source, such as Titanium, Chromium etc., by sputtering or by an arc-discharge. The transportation step is through a plasma medium. Plasma is a collection of charged particles, whose constituents can be influenced by magnetic fields and tend to travel in straight lines or "line of sight" from source to substrate. Different characteristics are imparted to the plasma depending upon the technique used to generate it. A PVD coating is formed when plasma constituents and reactive gases, such as nitrogen, combine on the component surface to form thin and very hard coatings such as Titanium and Chromium nitride.

PVD coatings involve the deposition of thin (2-10 microns; 0.0001" – 0.0004") films on the surface of tools and components.

Physical Vapor Deposition (PVD) coatings are widely prevalent across a diverse range of industrial, non-industrial and cosmetic applications. These coatings are extremely hard, with a low coefficient of friction; some can resist high operating temperatures and usually have an attractive range of colors.

Additionally, diamond tools have a closer cut tolerance than carbide does. When used in a cutting capacity, such as a diamond hole saw, diamond tools sand and erode the work material. The smoothing effect of diamond tools allows for high tolerance cuts that are exact. A higher thermal conductivity is another hallmark of the diamond tool. They stay cooler longer and better dissipate the heat created by friction. This means they won’t burn the workpiece and damage it. You can even use diamond tools without coolant and they still won’t overheat. This is valuable in keeping the workshop clean and free of slipping hazards.

Liquid nitriding is a subcritical surface enhancement process with one of the longest track records of success of any case hardening technology.

CAM permits the deposition of hard and ultra-low friction coatings at a very low temperature. Another major advantage is the ability to coat at low pressure, allowing more efficient use of the coating chamber and improved productivity.

A few factors will help you determine if you need a diamond or carbide core bit. Not the least of which is what kind of material you want to cut. To cut and grind hardened, super-dense materials, such as granite and concrete, you’ll want to use diamond. Diamond also works best on most non metallic materials such as fiberglass and composites.

Carbide drill bits consist of metal—they’re either solid tungsten carbide or have tips covered in a tungsten carbide cement. Professionals can use carbide drill bits in many different industries due to their long life and durability. They are more durable than hardened steel bits, but not as much as diamond. As with any metal drill bit, there will always be wear and tear, dulling, and breakage. The good news is you can sharpen carbide bits to extend their lifespan. However, after performing several sharpening sessions, there won’t be any material left. To work properly, carbide tips need coolant to prevent burning and overheating. It is important to note that coolant mixed with the effluent creates a sludge that is messy and needs constant cleaning.

HEF bushings are recognized worldwide for their excellent frictional and anti-seizure properties, and ability to withstand high loads.

PVD coatings can be applied on a diverse range of surfaces: steels and other ferrous metals; non-ferrous metals; glass; plastics; rubbers/elastomers. The most common industrial applications are metal cutting and forming tools; precision, high-tolerance industrial and automotive components; medical devices and instruments, etc.

Whereas liquid nitriding is a surface modification technology, PVD coating involves the deposition of thin (2-10 microns; 0.0001"-0.0004") films on the surface of components. The PVD coating process, conducted under high vacuum conditions, can be divided into three stages:

Besides its specific chemical constituents and the architecture of the sub-layers, the properties of a PVD coating depend on: ion energy; the degree of ionization of the metal ions, and mobility of the atoms condensing on the substrate surface. If a source material, such as a hydrocarbon gas, is used, a very hard, ultra low-friction Diamond-like-Carbon (DLC) coating can be deposited. This gas based process is referred to as PACVD - Plasma Assisted Chemical Vapor Deposition.

Superabrasive, diamond plated tools have a major edge over carbide—longevity and cut-rate set diamond tools apart from the rest. Initially, a diamond tool will cost more money, but this investment goes toward the extended life of the bit.

‘Decorative’ and consumer goods applications include door & plumbing hardware; kitchen appliances; firearms; shaving blades, etc. PVD technology is also used extensively for optical applications such as architectural glass and scratch-resistant plastics and glasses. PVD coatings also play an essential role in the fabrication of magnetic, semiconductor and opto-electronic devices.

There is a broad range of available PVD technologies, including conventional arc deposition and magnetron sputtering, coupled with technology enhancements that yield high deposition rates and thin films with high adhesion and diverse microstructures. HEF PVD coatings are deposited using three different technologies:

HEF Group is one of the leading global providers of PVD coatings – especially Diamond-like-Carbon (DLC) coatings. HEF specializes in DLC coatings for high-volume automotive applications; precision industrial components; firearm finishes, and medical applications. Currently there are 25 HEF coatings centers around the globe that offer PVD & DLC coatings using HEF designed and manufactured equipment that uses proprietary technology to ensure high deposition rates while maintaining low deposition temperatures, uniform and precise coating thickness, and excellent coating adhesion. Please contact us at sales@hefusa.net or (937) 323-2556 for all your PVD and DLC coating needs.

This high throughput plasma-arc method was developed by HEF's subsidiary, Northeast Coating Technologies (NCT), and dramatically reduces droplets normally associated with arc-deposited coatings. These coatings are a cost-effective solution for a wide range of carbon-free PVD coatings.
