Description: High velocity thermal spray coatings are offered. HVCC is a process where metal and/or ceramic materials are heated in spray gun, and then propelled towards a substrate as fine spray particles to build up a coating layer. Heating of the material in the spray gun typically takes place either by gas combustion or arc heating. Hypersonic spraying generally produce dense, high quality, metal and ceramic-metal coatings. These coatings are applied to prevent degradation of process equipment through the mechanism of corrosion and erosion coupled with high temperature. Life increase up to 3-4 times is common with no compromise on heat transfer and deterioration of base metal as temperature during spray process is only 100°C. The product lends itself very well to carbide containing cermets (ceramicmetal). In general, these carbides are blended fine grains in a metal binder - the carbides retaining their shape and hardness properties following spraying.
