低温共烧陶瓷氧化物/2024铝合金梯度复合材料的制备及性能研究
|
摘要
采用激光沉积技术,把低温共烧陶瓷氧化物混合粉(44%Si O2+20%B2O3+36%CaO)按照一定的梯度比例沉积在2024铝合金表面,得到陶瓷/金属梯度复合材料。重点研究了该梯度材料的显微组织结构、硬度、耐磨性能、结合力性能。结果表明,向2024铝合金基体中加入陶瓷氧化物混合粉末能使基体晶粒得以细化,显著改善基体的硬度、耐磨性能、结合力性能,其中均匀化热处理工艺并没有提升材料的耐磨性;固溶时效热处理后,复合材料梯度层最大硬度值是沉积态时基体层硬度值的2.6倍,结合性能约是沉积态时的2倍。
The ceramic/metal gradient composites were prepared by laser deposition of low temperature co-fired ceramic oxide mixture powder(44%SiO2+20%B2 O3+36%CaO) on the surface of 2024 aluminum alloy according to a certain gradient ratio. The microstructure, hardness, wear resistance and adhesion of the gradient material were studied in detail. The results show that, the matrix grain can be refined by adding ceramic oxide mixed powder to the matrix of 2024 aluminum alloy. The hardness, wear resistance and adhesion of the matrix are significantly improved. The homogenization heat treatment process does not improve the wear resistance of the material. The maximum hardness of the gradient layer is 2.6 times of that of the substrate in deposited state and the bonding property of the composites is about 2 times of that of the deposited state.
