Tungsten Carbide Thermal Spray Coatings

Can be ground to a 15 20 µin ra surface finish or superfinished to 5 µin ra.

Tungsten carbide thermal spray coatings.

Applied by hvof preferred or plasma spray. Hard chrome plating replacement candidates. Tungsten carbide wc co chrome carbide cr3c2 nicr our advanced coatings enhance the performance of your parts. This carbide is not only extremely hard but has a melting point of 5200 f.

Steel companies prefer using such coatings on guide rollers while oil businesses will routinely use tungsten carbide coatings for various applications which involve high wear resistance. A binder material is mixed with tungsten carbide powder to form the tungsten carbide coatings used in the thermal spray process. The properties of hvaf wc co tungsten carbide coatings on steel. Hvof tungsten carbide coating thermal spray process.

The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f. Tungsten carbide coatings are achieved through the hvof thermal spray process. Within this process fuel gas and oxygen are combusted in a high pressure chamber reaching temperatures up to 5 600 f 3 093 c. A a coatings material is a fine grade tungsten carbide cobalt aggregate powder for plasma spray.

Wc 12co thermal spray coatings are usually harder compared to coatings of wc 17co as a result of higher tungsten carbide levels in the coating. Check out these helpful resources. For the sake of comparison cobalt isn t even half as hard as tungsten carbide and its melting point is also much lower at 2460 f.
