Vanadium Nitride Coating
Vanadium nitride is a chemical compound of vanadium and nitrogen, achieved through a chemical vapor deposition (CVD) process. It is also known as VN, VNx, or VNit. Vanadium nitride is one of the earliest chemically vapor deposited coatings developed for wear resistance. It is used extensively for cutting tools, aerospace, and automotive components.
Vanadium nitride is a hard and wear resistant coating that exhibits lubricity at high temperature. It provides superior protection in dry running, low friction operating environments. It provides excellent oxidation, temperature, and abrasion resistance. The surface hardness of this coating can be up to 2800-3500 HV. It is available in various thickness, with a high tolerance for precise coating thickness, and it can be used on parts of nearly any size and shape.
Vanadium nitride has a smooth and non-reflective surface, which helps to reduce part surface contact, improving resistance to abrasion, galling, and wear. The coating also helps add an additional layer of protection against corrosion. Compared to other coatings, vanadium nitride stands out for ultra-high temperature operation, up to 1200° C, with no substantial surface degradation or loss of hardness at that temperature.
Additionally, this coating has a low coefficient of friction, making it ideal for applications that require precision coupling and fastening assemblies, as well as electroplating processes. It has excellent adhesion to many substrates and is an ideal coating for parts that include complex geometries and curved surface.
Vanadium nitride is a versatile coating that can be applied for a variety of industrial needs, including automotive components, machined parts, cutting tools, gears, and pistons. It is becoming increasingly popular for applications that require a multi-functional, high performance coating.
Vanadium nitride is a cost-effective coating that can increase the life of tools, components and other parts that are exposed to dry running and high temperature environments. It can be applied on stainless steel, brass, aluminum and other substrates by thermal spraying, physical vapor deposition (PVD), or ion plating. Applying vanadium nitride coating increases service life, reduces part replacement and maintenance costs, and saves time and money.
