305 DLC被膜を施したマグネシウム合金の疲労信頼性評価
詳細
The fatigue reliability of magnesium alloy coated with DLC film was examind. Main results obtained as follows: (1) By spattering Si as an intermediate layer, it succeeded in forming film of the DLC coat for the Mg alloy. (2) DLC film have function which burden and dispersion with load. Therefore generation of the fatigue crack is suppressed. (3) The precipitate of Mg_<17>Al_<12> grow the DLC film material according to heat treatment effect with the ion sputter, and the propagation of crack was arrested by this precipitate.
