陶瓷粒子增强铝合金在刚性和强度方面虽然没有陶瓷纤维增强铝合金大,但比一般铝合金大。例如20％的碳化硅陶瓷粒子增强铝合金的弹性系数比一般铝合金大50％,强度大20％,耐热性也比一般铝合金好,因此它的使用温度比一般铝合金高300℃。而且热膨胀小,耐磨损性也好。陶瓷粒子增强铝合金比陶瓷纤维增强铝合金价格低并且便于加工,因此使用改进的加工一般铝合金用的刀
Ceramic particle reinforced aluminum alloy in the rigidity and strength although not ceramic fiber reinforced aluminum large, but larger than the average aluminum alloy. For example, 20% silicon carbide ceramic particle reinforced aluminum alloy modulus of elasticity than the average 50% larger, 20% higher strength, heat resistance than the average aluminum alloy, so its use temperature higher than the average aluminum alloy 300 ℃. And small thermal expansion, abrasion resistance is also good. Ceramic Particle Reinforced Aluminum Alloy Ceramic fiber-reinforced aluminum alloy is inexpensive and easy to machine, so use an improved aluminum alloy knife
