Advancements in the thermal spray industry, such as the HVOF process, along with vigorous materials researc and development (various carbide alloys) are helping us meet requirements of increasingly sophisticated coating applications.
Depending on each application, there are many carbide alloys available to apply. The primary method is by HVOF which produces coatings that are near zero in porosity. They can be finished by grinding and super-finishing to less than 1 Ra (mirror-like). The photo shows a cross section of an HVOF coating (porous-free).
Other methods such as flame spray /fuse coatings, arc spray, and plasma spray are also used to produce carbide coatings for specific requirements such as rougher finishes for: Gripping, impact resistance, thicker layering, plasma-release coatings and more!
