Hvof Spray Process

Older process than hvof is a high velocity coating process like hvof uses discrete pulses explosions of oxygen fuel gas mixtures instead of a continuous coating jet to melt and propel powdered materials onto the surface of the substrate d gun is a proprietary process only one supplier available.

Hvof spray process. Fuel kerosene acetylene propylene and hydrogen and oxygen are fed into the chamber. Developing new cost effective coating materials providing low porosity coating with better corrosion resistance indirectly controlling the damage and the risk of catastrophic failure due to corrosion. As an essential feature of thermal spray coatings sprayed particles upon and after impact deform so as to interlock with the impact surface s profile. There are a number of hvof guns which use different methods to achieve high velocity spraying.

High velocity oxygen fuel hvof coating. Molten or semi molten materials are sprayed onto the surface by means of the high temperature high velocity gas stream producing a dense spray coating which can be ground to a very high. One method is basically a high pressure water cooled hvof combustion chamber and long nozzle. The study of the hvof spraying process is useful for.
