从粉末、粘结剂与脱脂三个方面分析了影响ＰＩＭ发展的关键因素。指出，粉末性能变化、粘结剂与脱脂技术的选择对产品的性能影响很大。严格控制粉末特性，选择适当的粘结剂体系和脱脂工艺参数是成功地控制ＰＩＭ的质量的基础。改善粉末性能和粘结剂体系，研究合理的脱脂参数是今后更应注意的问题。 From the powder, binder and degreasing analysis of the three key factors that affect the development of PIM. Pointed out that the change of powder properties, the choice of binder and degreasing technology has a great impact on the performance of the product. Strict control of powder properties, selection of appropriate binder systems, and degreasing process parameters are fundamental to successful control of PIM quality. Improve powder performance and binder system, the study of reasonable degreasing parameters should pay more attention to the problem in the future.
