测量了Ag-Bi-La合金在不同氧化条件下的表面硬度及沿深度方向的硬度变化。分析了合金的氧化硬度与合金成份、内氧化工艺的关系,从而确定了合金的最佳内氧化工艺,对确定合金中的镧含量也有一定指导作用。
The hardness of the Ag-Bi-La alloy under different oxidation conditions and its hardness along the depth direction were measured. The relationship between the oxidation hardness of the alloy and the composition of the alloy and the internal oxidation process was analyzed. The optimal internal oxidation process of the alloy was also determined, which was helpful to determine the content of lanthanum in the alloy.
