Tungsten Carbide Coating Thickness

This high bond strength far surpasses any spray on coating currently available.

Tungsten carbide coating thickness. The coating is very dense very hard very well bonded and suitable for use in the most aggressive wear environments. Finishes to a high metallic lustre when polished. The coating plays a very. The existence of chrome within the matrix greatly enhances the corrosion resistance of this coating over traditional wc co 12 type hvof coatings.

A a coatings hvof sprayed tungsten carbide was designed for use in thin coatings not more than 5mm 025 thick. Coating porosity 0 5 as measured in accordance with astm e2109. Ct2143 2 is a tungsten carbide cobalt chrome coating applied using the hvof process. The right image shows the much smoother tungsten carbide coating applied by hvof.

Mechanical components subjected to severe environments are usually coat with cermet based wc co cr thermally sprayed coating. Coating thickness mm in 0 08 0 003 0 13 0 005 surface finish ra 4 4. Hvof tungsten carbide has a bonding strength to the substrate of 80 mpa 10 ksi. A a coatings plasma sprayed tungsten carbide was designed for use in thin coatings not more than 5mm 020 thick.

A tungsten carbide coating provides the same toughness of a solid tungsten carbide part but at a lower price point. 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. Guide to substrate preparation for thin film coatings. The coating thickness varies based on the size of the part but is between 0 5mm to 3mm with a hardness of 91 hra and a mirror polish to keep friction at a minimum.

If sprayed thicker the probability of cracking and delamination will increase rapidly as is the case of thick coatings of all fine powders. If sprayed thicker the probability of cracking and delamination will increase rapidly as is the case of thick coatings of all fine powders. Does not contain cobalt or other metal binder materials used in cemented carbides and thermal spray coatings. 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.

The left image shows a hard chromium coating. Coating as applied is light gray. Tungsten carbide wc co chrome carbide cr3c2 nicr our advanced coatings enhance the performance of your parts.
