Abstract

The invention provides a target magnetron sputtering device and a film coating method used for powder particle surface film coating. The target magnetron sputtering device comprises a vacuum chamber, a roller with openings at two ends, two support rollers, a motor, a speed regulation device, two magnetron sputtering target frames and a sputtering power source, wherein each support roller is provided with a limiting inclined face. The support rollers are connected with the speed regulation device. The roller is directly placed on the support rollers and driven to rotate through the support rollers. Target materials are arranged at the positions of the openings at the two ends of the roller. During magnetron sputtering film coating, a grinding ball and powder are simultaneously placed into the roller, the rotating speed of the motor is regulated, the grinding ball and powder particles in the roller are enabled to drop in a parabola mode, sputtering stream injected from the openings of the roller is deposited on the falling powder, and film with good evenness is obtained after a certain period of time. The target magnetron sputtering device and the film coating method used for the powder particle surface film coating are large in technological handling capacity, low in operational cost and suitable for industrial production.
