Tungsten Carbide Thermal Spray Coatings

A a coatings material is a fine grade tungsten carbide cobalt aggregate powder for plasma spray.

Tungsten carbide thermal spray coatings.

In the agricultural industry tungsten carbide is the preferred material for plough shares as well as cutters and other tillage equipment. These coatings are recommended for resistance to wear by abrasive grains hard surfaces fretting and particle erosion. 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. Tungsten carbide coatings are achieved through the hvof thermal spray process.

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 properties of hvaf wc co tungsten carbide coatings on steel. It produces the best coatings for low temperature wear resistance of all tungsten carbide powders. 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 wc co chrome carbide cr3c2 nicr our advanced coatings enhance the performance of your parts. Check out these helpful resources. Can be ground to a 15 20 µin ra surface finish or superfinished to 5 µin ra.

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. This carbide is not only extremely hard but has a melting point of 5200 f. Hard chrome plating replacement candidates.
