PVD (Physical Vapor Deposition) coating is widely known for its durability and performance in industrial settings, but it also plays an essential role in decorative applications. In our latest blog post, we explore the aesthetic advantages of PVD coating, from its beautiful finishes to its ability to enhance the visual appeal of products. Whether it’s jewelry, watches, or other consumer goods, PVD coating adds elegance and durability that lasts.

Most PVD coatings are thin, hard refractory nitrides (e.g., CrN, TiN). These materials are naturally chemically inert and resistant to corrosion, which is why PVD coatings are often claimed to be corrosion resistant. However, most of the commercially available PVD coatings are being deposited at less than 3 microns (μm), which is relatively thin for the purpose of corrosion protection. Moreover, a typical PVD coating contain intrinsic defects (such as pinholes and craters) due to the nature of the deposition process. The thin PVD layer with these defects can expose the substrate, leaving it vulnerable to corrosion.

Firearms are intricate machinery aimed at delivering projectiles through a firing mechanism. From a mechanical point of view, all the moving parts of firearms affect the safety, accuracy, and durability through a single or a combined phenomenon of wear, tear, and oxidation. For years, firearm users have tried a variety of material selections and treatment processes to enhance the functionality of shooting. PVD (Physical Vapor Deposition) technology emerged from the cutting tool industry and finds its way into the firearm sector with its superior wear and corrosion resistance.
