High-velocity combustion or oxyfuel spraying started up more than 35 years ago with the development of the detonation gun or D-Gun process. Described as the newest and fastest growing member of the family of coating, or surfacing, technologies known collectively as thermal spray'', HVOF processes have carved out a significant, specialized niche in the thermal spray coating business, particularly for the deposition of wear-resistant carbide coatings. HVOF processes are able to deposit very dense coatings, typically with reduced changes in the phase composition of the material, compared with plasma arc spray processes. HVOF also offers a number of potential advantages over, and alternatives to, competing processes, including lower capital costs, portability, and ease of use in the field.
