国内外钛合金精密铸造型壳材料的发展概况

Development of Shell Mold Materials for Ti Alloy Investment Casting in Domestic and Foreign Countries

介绍了国内外铸造钛合金用石墨型、难熔金属面层及氧化物陶瓷型面层型壳材料的发展与应用状况 ,比较了国内外在这一领域的技术差距 ,提出应开发。

The development and application status of rammed graphite mold, refractory metal powder,face coated mold shell and oxide face coated ceramic mold shell for cast Ti alloy in domestic and foreign countries were introduced. The technological gap between home and abroad was compared. The suggestion on developing new and non pollution molding materials for mold shell was proposed.
