金属陶瓷是一种既象钢铁一样坚硬,又同陶瓷一样耐高温、耐腐蚀的复合材料。最近,日本旭玻璃公司推出一种含铁化合物的金属陶瓷材料,铁化合物的作用可提高陶瓷强度。该公司开发的金属陶瓷是将二硼化锆与铁粉混合,与一种粘结剂拌合,然后在一橡皮压制机中经热压结合而成的。通常制造金属陶瓷材料较为简易,只要在氧化铝中加入一些金属铬;或者在碳化钛中加 Cermet is a kind of composite material that is as hard as steel and as high temperature and corrosion resistant as ceramics. Recently, Asahi Glass Co., Ltd. has introduced a metal-ceramic material containing iron compounds, which can enhance the strength of ceramics. The company’s development of cermets is the mixing of zirconium diboride with iron powder, with a binder, and then by a press in a rubber press. It is generally easier to manufacture cermet materials as long as some chromium metal is added to the alumina or titanium carbide plus
