Typical lead times are 3 to 5 days. Test parts and samplings take more time as fixturing and process design is required.

After the precision CNC machining of various products for different industries, machinists often need additional finishing operations to improve their quality.

The two main PVD coating processes are Sputtering and Thermal Evaporation. Sputtering involves bombarding the target coating material with a high-energy electrical charge. This process causes it to “sputter” off atoms or molecules onto the target material.

The PVD coating technology involves altering the molecular properties of a metal's surface by depositing thin films of materials on a part's surface. The distinctive blend of appearance and functionality establishes this process as a unique element in metalworking.

Since its initial discovery, Physical Vapor Deposition (PVD) coating has discovered various new applications. This process was Initially explored for military purposes to enhance cannon durability and minimize spin in ballistics.

Prior to coating, substrates (tools and components) need to be free of any foreign matter, oils and grease on the surfaces that are to be coated, but also in all other areas. The cleaning process is an essential element that determines the adhesion and thus influences the performance of the coated part or tool. All parts are cleaned by Ionbond prior to coating, using a designated process. Ionbond encourages customers to discuss the optimum requirements for their substrates in order to ensure top performance.

A reliable service provider should implement a stringent quality control process to guarantee optimal results for your products.

Ionbond operates in 15 countries around the world and provides thin film coating services. Its coatings improve the life, quality, function, efficiency and appearance of tools and parts.

The strong resistance to wear and corrosion in PVD coatings is beneficial for the repeated use and sterilization of medical devices. Additionally, the thin and lightweight nature of PVD coatings holds significance in medical applications.

In the automotive sector, PVD coating is frequently utilized to enhance the durability and performance of PVD-coated car components. This coating is commonly added to engine parts like pistons and camshafts to decrease friction and boost wear resistance.

The PVD,coating process, is a line of sight process which requires substrates to be rotated in the chamber (from single to triple rotation) in order to achieve the required homogeneous coverage and thickness. Coating of inner diameters in PVD is restricted to a depth equal to the diameter of the opening.

Applying these coatings at the atomic level provides control over film structure and density. This allows for the customization of attributes like hardness and adhesion.

PVD coating is biocompatible, ensuring its safety for contact with human tissue without causing adverse reactions. This quality makes PVD coatings well-suited for medical device manufacturing and implants in direct contact with the human body.

PVD coating is a method where a solid material transforms into vapor to cover another material. The PVD coating process involves several steps:

After applying the PVD coating, additional processing of the coated substrate may be necessary. This can involve heat treatment to enhance coating adhesion and density or surface finishing processes to achieve the desired surface roughness and geometry. These post-deposition procedures contribute to improving the overall performance of the PVD coating.

This guide takes you through the PVD coating process, detailing its key benefits and applications. You will also learn the differences between PVD and other coating methods and how you can get the best from this process.

PVD coatings are known for their hardness and resistance to wear and are well-suited for high-use surfaces. This durability results from the vacuum environment during PVD application. The process eliminates oxygen and moisture and prevents oxidation or other degradation.

PVD coatings are typically less dense and less uniform but can be applied quickly to a broader range of materials. In contrast, CVD coatings are denser and more uniform but are constrained to specific materials and have a longer application time.

Moreover, PVD coatings are usually thin and lightweight. These benefits are essential in aircraft where managing weight is crucial.

PVD coatings are dense with superior adhesion and durability compared to powder coatings. However, powder coatings are generally less expensive and offer a broader range of colors and finishes.

PVD coating can deposit metals, alloys, and ceramics, while powder coating is usually limited to organic polymers. PVD coating occurs in a vacuum chamber at high temperatures with processes like sputtering or evaporation. Powder coating occurs at lower temperatures, using an electrostatic charge to deposit the coating material.

Ensuring proper control of these conditions is crucial to achieving an even coating deposition with the desired properties.

In electronics, PVD coatings applied on components offer a protective barrier, extending the device’s lifespan by shielding it from corrosion, wear, and abrasion. Furthermore, PVD coating enhances the electrical and thermal conductivity of electronic components. Ultimately, it contributes to the durability and reliability of these devices.

In aerospace applications, PVD coating is commonly employed for various reasons. Its durability and strong resistance to wear and corrosion make it advantageous for materials in the aerospace industry. PVD coatings also excel in withstanding high temperatures. Thus, they are well-suited for aircraft and other aerospace vehicles that experience extreme temperature fluctuations.

The coatings can be deposited as mono-, multi- and graded layers. The latest generation films are nano-structured and superlattice variations of multi-layered coatings, which provide enhanced properties. The coating structure can be tuned to producing the desired properties in terms of hardness, adhesion, friction etc. The final coating choice is determined by the demands of the application. The coating thickness ranges from 2 to 5 µm, but can be as thin as a few hundred nanometers or as thick as 15 or more µm. Substrate materials include steels, non-ferrous metals, tungsten carbides as well as pre-plated plastics. The suitability of the substrate material for PVD coating is limited only by its stability at the deposition temperature and electrical conductivity.

Alongside their functional benefits, PVD coatings present a superior appearance compared to traditional coatings. This enhanced visual appeal is attributed to the ability of PVD coatings to reflect light. This gives them a brighter and shinier appearance. Objects coated with PVD coating possess a visual appeal unparalleled by any other coating currently available.

The Ionbond™ PVD process is used for the deposition of coatings made of nitrides, carbides and carbonitrides of Ti, Cr, Zr and alloys like AlCr, AlTi, TiSi on a large range of tools and components. Applications include cutting and forming tools, mechanical components, medical devices and products that benefit from the hard and decorative features of the coatings. The typical process temperature for PVD coatings is between 250 and 450 °C. In some cases, Ionbond™ PVD coatings can be deposited at temperatures below 70 °C or up to 600 °C, depending on substrate materials and expected behavior in the application.

Most commonly used methods are sputtering and cathodic arc. In sputtering, the vapor is formed by a metal target being bombarded with energetic gas ions. Cathodic arc method uses repetitive vacuum arc discharges to strike the metal target and to evaporate the material.

PVD is a method for producing metal-based hard coatings by means of generation of partially ionized metal vapor, its reaction with certain gases and by forming a thin film with a specified composition on the substrate.
