Tungsten Carbide Coating On Steel
The properties of hvaf wc co tungsten carbide coatings on steel.
Tungsten carbide coating on steel. We can even surface treat hardened parts. The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f. Replaces tungsten carbide coating on stainless steel. 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.
Carbide coatings are typically used for wear resistance to abrasion erosion galling and fretting. For more than 70 years coatings in their various forms have been the standard to improve resistance towards wear. Most carbide coatings are applied by hvof to achieve the densest and most well bonded coatings available by thermal spray. 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.
Expanite the danish pioneer specializing in surface hardening of stainless steel and titanium is widely replacing coatings in a variety of demanding applications. An electronically controlled pulsed arc micro welding process which metallurgically bonds tungsten carbide uniformly to a steel substrate. 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 blade was used to stir the mixture of su lfuric acid h 2.
Hardide coatings is the leading global innovator and provider of advanced tungsten carbide tungsten metal matrix composite coatings. Our tungsten carbide coating works at near ambient temperatures to ensure that your work piece doesn t become embrittled or warped. Plasma sprayed carbide coatings may be selected to achieve a higher texture as sprayed. Our coatings significantly increase the life of critical metal parts operating in abrasive erosive corrosive and chemically aggressive environments.
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. Within steel and metals production hvof tungsten carbide coatings and tungsten weld coatings are widely used from ore production through finished product. Carbinite is a tungsten carbide or stellite carbide alloy that can be applied to most metals using a process called electro spark deposition esd yielding a true metallurgical bond. This high bond strength far surpasses any spray on coating currently available.
