用自制的化学气相沉积装置在Ａｌ２Ｏ３颗粒表面获得了Ｎｉ涂层，并通过负压铸渗工艺获得了Ａｌ２Ｏ３颗粒／耐热钢基复合材料，考察了其高温磨料磨损特性．结果表明：Ｎｉ涂层能显著改善Ａｌ２Ｏ３与耐热钢的湿润性，从而解决了Ａｌ２Ｏ３颗粒在耐热钢液中均匀分散的难题，所得复合材料具有优良的高温磨料磨损抗力
Ni coating was obtained on the surface of Al2O3 particles by a homemade chemical vapor deposition device, and Al2O3 particles / heat-resistant steel matrix composites were obtained by negative pressure infiltration and infiltration process. The wear characteristics of high temperature abrasive were investigated. The results show that the Ni coating can significantly improve the wettability of Al2O3 and heat-resisting steel, which solves the problem of uniform dispersion of Al2O3 particles in the heat-resistant molten steel. The obtained composite has excellent high-temperature abrasive wear resistance
