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18－53％可调，为高温磨料磨损工况提供了新材质。
Al 2 O 3 particles were treated by self-made chemical vapor deposition (TiN) coating on the surface of the Al 2 O 3 particles. 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 at 18-53% New material is provided for hot abrasive wear conditions.
