【Abstract】 The rapid manufacturing technique for some special shaped thin shells is preliminary studied. The thin shells can be used for protecting some fragile and expensive parts which cannot be sprayed directly. Our attention is focused on how to get thin shells by means of PSFP (Plasma-Spray Forming Parts). The PSFP experiments are carried out by using AT3 (Al 2O 3 ·TiO 2) ceramic powder as spraying material. Some key technologies of the processes are discussed.更多还原
