日本:1日本开发了一种轻型超耐热材料,在2000℃的温度下也不会剥离.美国的宇宙飞船,是在钛合金主体上用接合剂敷贴厚数厘米瓷砖以便绝热,在进入大气层时,表面温度达2000℃,这时瓷砖往往就断裂或剥离,而日本开发的新材料是钛在激光加热下熔融并与氮结合生成耐热性高的钛.用高压气体喷射法使氮化钛的量逐渐增加,形成重叠的几层,且层间没有界面,使主体和绝热材间难以剥离.这样形成的厚度约0.6mm的超薄耐热材,约在1700℃高温下经50次反复试验,一次也没有发生断裂.
Japan: 1 Japan has developed a light-weight, super-heat-resistant material that does not peel at temperatures of 2000 ° C. The U.S. spacecraft uses centimeter-thick ceramic tiles with a bonding agent on the titanium alloy for heat insulation. Atmosphere, the surface temperature of 2000 ℃, then the tiles tend to fracture or peel off, and Japan developed a new material is titanium under laser heating and melting with nitrogen to form high-heat-resistant titanium with high-pressure gas jet method of nitrogen The amount of titanium gradually increased, the formation of overlapping layers, and no interface between the layers, so that the main body and the insulation is difficult to peel the so formed thickness of about 0.6mm ultra-thin heat-resistant material, at about 1700 ℃ high temperature by 50 Repeated test, once did not happen fracture.
