用现代最尖端技术制造的飞机引擎、气体涡轮机等,经常要求更高的性能和可靠性(安全性),目前正在进行承担这种材料开发的竞争。即使超合金的材料,最高使用温度在1000℃左右也有趋于极限的问题。为了打破这个障碍(记录),使陶瓷粒子在合金中分散而制成的耐热复合材料,不能象熔炼普通合金那样,仅仅通过充分掺混陶瓷粉就能制得。因为陶瓷的比重要比一般金属小,不能混合均匀。1982年4月开始,有关部门应用粉末冶金技术,进行了
Aircraft engines, gas turbines and the like, which are made with state-of-the-art technology, often require higher performance and reliability (safety) and are currently engaged in the development of this material. Even if the superalloy material, the maximum operating temperature of about 1000 ℃ also tends to the limit of the problem. In order to break this barrier (record), the heat-resistant composite material made by dispersing the ceramic particles in the alloy can not be obtained merely by thoroughly mixing the ceramic powder, as is the case with ordinary alloys. Because the specific gravity of the ceramic than the average small, can not mix evenly. Since April 1982, the relevant departments have applied powder metallurgy technology
