| 要旨 | Concerning the plasma thermal spray of Sn alloys, we have confi rmed through EPMA analysis that the material ratio of the thermal spray coating differs from the material ratio of the thermal spray raw material. We have verifi ed that this phenomenon is due to the high temperature of the plasma exceeding the evaporating temperature of the component elements. Therefore, by conducting thermal spray using thermal spray raw materials which are adjusted beforehand with consideration to changes in the component ratio, a thermal spray coating of the target component ratio was achieved. Furthermore, by conducting heat treatment that causes composition changes on the thermal spray coating after thermal spray, an adhesion power that exceeds shear strength was attained. The resulting thermal spray coating does not separate from the surface of the base material, as external forces cause breakage to occur within the coating. Therefore, a thermal spray coating with high reliability was achieved. |
