摘　　要：研究了梯度层数目对激光加热合成Ａｌ２Ｏ３／Ｔｉ梯度功能材料的组织性能影响．结果表明：梯度层数越少，则其显微组织越差；梯度层数越多，则其显微组织越均匀，但成型困难越大，最适宜的层数为１０．The effect of gradient layer number on microstructure and property of Al2O3-Ti functionally gradient material by laser spot irradiation was studied. The result shows that,the less gradient layer number,the worse microstructure of FGM is,the greater gradient layer number,the better the microstructure and property of FGM is,but more difficult the fabrication of FGM is. The most appropria gradient layer number is 10.
