用自制的化学气相沉积装置对Ａｌ２Ｏ３颗粒进行表面ＴｉＮ涂层处理后，通过负压铸渗工艺获得了Ａｌ２Ｏ３颗粒耐热钢基复合材料，并使氧化铝颗粒体积分数在２３％～５７％可调，为高温磨料磨损工况提供了新材质。
Al2O3 particles were treated by self-made chemical vapor deposition (PVD) on the surface of TiN coating. The Al2O3 particles-heat-resistant steel matrix composites were obtained by negative pressure infiltration and infiltration process, and the volume fraction of alumina particles was adjustable from 23% to 57% , Provides a new material for high-temperature abrasive wear conditions.
