Research Abstract |
Lining magnesium alloys with hard powder by shot peening was carried out. The hard materials are bonded to the surface of the magnesium workpieces due to the collision of small steel balls. To fix the hard powder to the surface of the workpiece, the hard powder was set on an uneven surface. To facilitate easy fixing of powder, lining the workpiece with the powder sandwiched between two aluminum foil sheets was also attempted. In this experiment, a centrifugal shot peening machine with an electrical heater was employed. The workpieces were magnesium alloys, and the hard powder was commercially pure chromium, cemented carbide or ceramic. The effects of collision speed and the processing temperature on the bondability were examined. The wear resistance was also evaluated by a wear test. It was found that the hard powder was successfully bonded to the surface of workpieces by the shot lining process.
