由于对金属材料具有相反性能的要求,为此研制成功了梯度功能材料,与金属一陶瓷结合材料相比,这种材料的性能不是跳跃而是连续过渡的,这种性能的梯度化是由局部合金浓度或组织参数的变化引起的。由这种梯度材料制成的构件,可以有很硬的表面层,同时又具有韧性良好的心部。 Due to the opposite performance requirements of metal materials, gradient functional materials have been successfully developed for this purpose. Compared with metal-ceramic bonding materials, the performance of such materials is not a jump but a continuous transition. The gradient of this performance is caused by local Alloy concentration or tissue parameters caused by changes. Components made from such graded materials can have very hard surface layers, as well as a tough core.
