Tungsten Carbide Coating On Steel

At asb industries tungsten carbide thermal spray coatings are the most frequently applied wear resistant surface treatments on the market.
Tungsten carbide coating on steel. Within steel and metals production hvof tungsten carbide coatings and tungsten weld coatings are widely used from ore production through finished product. Wc 10ni and tungsten carbide 12 wt w cobalt wc 12co coating deposited onto medium carbon steel cast steel bs 3100 gr a3 blade. The properties of hvaf wc co tungsten carbide coatings on steel. In both coating methods the wolfram tungsten carbide powder is sprayed on the surface of the work element as plastic and clings onto the previously sprayed base component.
This high bond strength far surpasses any spray on coating currently available. The blade was used to stir the mixture of su lfuric acid h 2. Carbide coatings are typically used for wear resistance to abrasion erosion galling and fretting. When applied to a substrate the hvof cemented tungsten carbide coating immediately bonds to the surface resulting in high bond strength and extreme wear resistance.
Our coatings significantly increase the life of critical metal parts operating in abrasive erosive corrosive and chemically aggressive environments. Replaces tungsten carbide coating on stainless steel. For more than 70 years coatings in their various forms have been the standard to improve resistance towards wear. Plasma sprayed carbide coatings may be selected to achieve a higher texture as sprayed.
The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f. A multitude of accepted applications show dramatically reduced maintenance costs and improved production quality. Expanite the danish pioneer specializing in surface hardening of stainless steel and titanium is widely replacing coatings in a variety of demanding applications. Our tungsten carbide coating works at near ambient temperatures to ensure that your work piece doesn t become embrittled or warped.
We can even surface treat hardened parts. 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. A wolfram carbide hard metal coating is either carried out with self fluxing powder flame spraying according to din en iso 14920 1999 or with hvof high speed flame spraying. An electronically controlled pulsed arc micro welding process which metallurgically bonds tungsten carbide uniformly to a steel substrate.
