Tungsten carbide thermal spray coatings.
Can be ground to a 15 20 µin ra surface finish or superfinished to 5 µin ra.
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.
Hard chrome plating replacement candidates.
Tungsten carbide wc co chrome carbide cr3c2 nicr our advanced coatings enhance the performance of your parts.
A binder material is mixed with tungsten carbide powder to form the tungsten carbide coatings used in the thermal spray process.
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.
This carbide is not only extremely hard but has a melting point of 5200 f.
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.
The properties of hvaf wc co tungsten carbide coatings on steel.
In the agricultural industry tungsten carbide is the preferred material for plough shares as well as cutters and other tillage equipment.
It produces the best coatings for low temperature wear resistance of all tungsten carbide powders.
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.
