【摘要】 使用X射线衍射仪和显微硬度计测定了LY12铝合金微等离子体氧化陶瓷膜沿深度方向 的相分布及显微硬度变化曲线.结果表明,铝合金微等离子体氧化陶瓷膜主要由 α-Al、γ- Al相组成,从表层到里层,α-Al相含量逐渐增加.膜的显微硬度沿深度方向变化同 α- Al含量变化一致,致密层中显微硬度大于 HV1500,极值点达到 HV2300.

【Abstract】 The phase and microhardness distributions in ceramic coating formed by microplasma oxidation on LY12 aluminum alloy were investigated using X - ray diffractometer and microhardness tester. The results show that the ceramic coating contains mainly a - Al2 O3, y - A12 O3 phases, and the a - A12 O3 content gradually increases from outer layer to inner layer of coating. The change of microhardness in different depth of coatings is consistent to the change of a - A12O3 content. The microhardness in compact layer is over 1500HV, and its maximum value can reach 2300HV.
