Progress in research on dehydrogenation of titanium hydride and manufacturing processes of spherical titanium powders

钛粉是钛和钛合金粉末冶金的重要原料,而氢化钛粉脱氢是用于制造低成本钛粉的氢化脱氢工艺关键环节之一。球形钛和钛合金粉是用金属增材制造工艺制造高性能、形状复杂的钛和钛合金零部件的重要原料。本文对氢化钛粉脱氢的原理、脱氢方法、球形钛粉制造方法进行了介绍和比较。目前常用的氢化钛脱氢方法分为粉末冶金和松散粉末两种方法。目前常用的球形钛和钛合金粉制造方法主要包括雾化法,等离子球化法和激光球化法。

Titanium powder is an important raw material for titanium and titanium alloy powder metallurgy,and dehydrogenation of titanium hydride powder is one of the key steps of the hydrogenation-dehydrogenation process for manufacturing low-cost titanium powder.Spherical titanium and titanium alloy powders are important raw materials for manufacturing high-performance complex shaped titanium and titanium alloy parts using additive manufacturing processes.The two commonly used methods for dehydrogenation of titanium hydride powder are powder metallurgy method and loose powder method.The common manufacturing processes of spherical titanium and titanium alloy powders mainly include atomization,plasma spheroidization and laser spheroidization processes.
