[上接本刊2013年第4期第44页]2.新材料新工艺开发方向2.1高密度制品(1)新材料的开发方向是:需要开发粉末冶金新材料替代锻造材料,工程师需要力学性能与锻造制品接近的高密度粉末冶金制品。需要提高粉末的压制性能,市场需要粉末颗粒具有高的压缩性能,能够用于压制出密度较高的坯料。需要开发新型的压制润滑剂,为了粉末冶金零件坯料在压制后可以脱模,一般需要加入
[上 接 本 2013 2013 No. 4 第 44 页] 2. New materials and new technology development direction 2.1 High-density products (1) The development direction of new materials is: the need to develop new materials for powder metallurgy alternative forging materials, engineers need mechanical properties High-density powder metallurgy products close to forged products. There is a need to increase the pressability of the powder, requiring the powder particles to have high compression properties that can be used to compact blanks of higher density. Need to develop a new type of compression lubricant, in order to powder metallurgy parts blanks can be stripped after pressing, the general need to join
