Tungsten Carbide Thermal Spray Coatings

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 thermal spray coatings.

This carbide is not only extremely hard but has a melting point of 5200 f. It produces the best coatings for low temperature wear resistance of all tungsten carbide powders. Hard chrome plating replacement candidates. A binder material is mixed with tungsten carbide powder to form the tungsten carbide coatings used in the thermal spray process.

In the agricultural industry tungsten carbide is the preferred material for plough shares as well as cutters and other tillage equipment. 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. The properties of hvaf wc co tungsten carbide coatings on steel.

Tungsten carbide wc co chrome carbide cr3c2 nicr our advanced coatings enhance the performance of your parts. Applied by hvof preferred or plasma spray. 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.

These coatings are recommended for resistance to wear by abrasive grains hard surfaces fretting and particle erosion. Can be ground to a 15 20 µin ra surface finish or superfinished to 5 µin ra. Check out these helpful resources.
