摘　　要：采用等离子喷涂成形法制造某些特殊材料的薄壁件 ,以保护那些不允许直接进行等离子喷涂的脆弱零件及贵重零件。以Al2 O3 ·TiO2 粉末为例进行试验研究 ,制得厚度为 0 .5～ 1.0mm的薄壁件 ,分析了原模结构、原模表面处理、脱模方法等关键技术问题。The thin shell parts for special materials was manufactured by using plasma spray forming technique, which could protect fragile and expensive parts that might not be sprayed directly. A thin shell part with 0.5 mm thickness was made of Al 2O 3·TiO 2 ceramic powder. The key techniques as structure and surface treatment of prototype and demouding method were discussed.
