摘要
钛及其合金因密度低、强度高、耐蚀性好、生物相容性好等特点被广泛应用于航空航天,汽车舰船,石油化工,生物医疗等领域。本文主要针对钛及其合金的粉末冶金制备技术研究现状进行了介绍,从制粉和成形致密化两个方面介绍了国内外的制备技术,并且指出粉末冶金钛合金未来发展的关键是微细低间隙钛粉的制备,大尺寸坯料的制备和高性能烧结坯的制备。
Titanium and its alloys are widely used in aerospace,automobile and ship,petrochemical industry,biological medicine and other fields because of their low density,high strength,good corrosion resistance and good biocompatibility. The article mainly aims at the preparation technology of powder metallurgy of titanium and titanium alloys,current situation are introduced. Powder manufacturing and densification at home and abroad are introduced. It is pointed out that the key for the future development of powder metallurgy titanium alloys is the preparation of low clearance element fine titanium powder,large size green and high performance sintered preform.
