Description

Technical Field

[0002] Cold spray coating is a method that uses supersonic carrier gas to spray powder at room temperature or at a relatively low temperature without heating, and coats it on the surface of the object to be coated. In this method, the particles accelerated by the supersonic jet gas flow collide with the metal or ceramic substrate and are coated on the metal or ceramic substrate. The variables of the coating process include: the accelerated gas temperature, gas velocity, and particle size. Since the principle is to make the particles accelerated to a high speed collide with the unheated substrate for coating, the coating efficiency varies according to the various materials to be coated. The greater the speed of the accelerated particles, the greater the coating efficiency, and it increases sharply when it is greater than or equal to a certain speed.
