Tungsten Carbide Thermal Spray Coatings

Applied by hvof preferred or plasma spray.

Tungsten carbide thermal spray coatings.

These coatings are recommended for resistance to wear by abrasive grains hard surfaces fretting and particle erosion. In the agricultural industry tungsten carbide is the preferred material for plough shares as well as cutters and other tillage equipment. Tungsten carbide wc co chrome carbide cr3c2 nicr our advanced coatings enhance the performance of your parts. Hvof tungsten carbide coating thermal spray process.

Can be ground to a 15 20 µin ra surface finish or superfinished to 5 µin ra. Hard chrome plating replacement candidates. 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. The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f.

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. This carbide is not only extremely hard but has a melting point of 5200 f. The properties of hvaf wc co tungsten carbide coatings on steel. A binder material is mixed with tungsten carbide powder to form the tungsten carbide coatings used in the 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. 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. Tungsten carbide coatings are achieved through the hvof thermal spray process.
