Abstract

PURPOSE:To easily obtain a coating having high adhesive strength at a relatively low temp. by bringing coating materials into sliding contact with each other in a vacuum or in an inert gas atmosphere, and allowing the generated sparks of powder to directly collide with the surface of a member to be coated. CONSTITUTION:The inside of a high-vacuum chamber 1 is evacuated by a vacuum pump 2, and the coating material 5 fixed on the surface of a sliding plate 3 is brought into contact with the coating material 5 provided on the surface of a rotary disk 4 rotating in the direction as shown by the arrow at a high speed. The coating material 5 is formed from powdery or solid metal, nonmetal, ceramics, etc. The generated high-temp. and fast sparks 6 of powder or vapor are allowed to directly collide with the surface of the front coating member 7. The sparks 6 of powder are cooled by the surface, and a coating layer 8 is formed. As a result, a coating having high adhesive strength can be obtained at a relatively low temp. without the need for a large-scale energy source, and the fine powdery particles are made amorphous by the quenching effect.
