Abstract:

Generally speaking, thermal spray consists of the heating and accelerating of solid particles by injecting them into a hot gas strearn, then impacting them onto a substrate to form a coating. There are a wide variety of techniques for carrying this out. The heated gas stream can be produced by a DC arc plasma arc spraying, by combustion of a tuel such as kerosene high velocity oxygen fliel, or HvOF, or even simple heating of compressed air cold dynamic gas spray, or CDGS. Each method has a characteristic range of gas velocities and temperatures. For example, plasma arc spray can produce extremely high temperature in excess of 10,000 0C but velocities below 1,000 flisec. On the other hand, HvOF produces much higher velocities, but temperatures in the 2,000 -
