摘要１ＩＮＴＲＯＤＵＣＴＩＯＮＤｕｒｉｎｇｔｈｅｐａｓｔｆｅｗｙｅａｒｓ，ｐｏｗｄｅｒｉｎｊｅｃｔｉｏｎｍｏｌｄｉｎｇ（ＰＩＭ）ｈａｄｅｍｅｒｇｅｄａｓａｎａｄｖａｎｃｅｄｍａｎｕｆａｃｔｕｒｉｎｇｔｅｃｈｎｏｌｏｇｙ［１］．Ｔｈｅｃｏｍｂｉｎａｔｉｏｎ... The processing of the thermal debinding in vacuum using water atomized 316L stainless steel powder and waxbased multicomponent binder were systemically studied. The thermal debinding velocity in vacuum was analyzed under the conditions of different binders and different rising temperature rates, especially the low temperature thermal debinding kinetics in vacuum. The processing of thermal debinding in the flowing H2 was also compared with the processing in vacuum. The binder removal rate in vacuum was faster than that in the flowing H2, but the control of defect is more difficult. The reason was that the gas pressure in the green parts was higher than that in environment.
