采用粉末冶金法制备了添加银和钡盐（BaCrO 4、BaMoO 4）的Ni 3Al基复合材料。结果表明，添加Ag和BaCrO 4的Ni 3Al基复合材料在室温~ 800 °C范围内具有连续润滑性能，摩擦系数在0.29 ~ 0.38之间;添加Ag和BaMoO 4的Ni 3Al基复合材料也具有良好的润滑性能，在较宽的温度范围内摩擦系数在0.28 ~ 0.35之间。在较宽的温度范围内，低的摩擦系数可以归因于银和钡盐的协同效应。
Ni3Al matrix composites with addition of silver and barium salt (BaCrO4, BaMoO4) were fabricated by powder metallurgy. It was found that from room temperature to 800 °C, Ni3Al matrix composite with addition of Ag and BaCrO4offers the continuous lubrication properties, and its friction coefficient ranges from 0.29 to 0.38; Ni3Al matrix composite with addition of Ag and BaMoO4also offers the favorable lubricating properties; the friction coefficient ranges from 0.28 to 0.35 in a wide temperature range. The low friction coefficient in a wide temperature range could be attributed to the synergistic effect of Ag and barium salts.
