What is cold gas spray?
Cold spray can be considered as a new “HVOF” technology where the kinetic energy is increased while the thermal energy is lowered. With Cold Spray it is possible to spray virtually oxide free coatings.
The coating material particles are being accelerated in a heated gas stream (600 °C), up to a particle velocity of >1000m/s. The extreme high particle velocity combined with the low particle temperature results is very dense and oxide free coatings.
Applications are found in the automotive industry, corrosion protection and electronics industry.
