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 >1200m/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.
