一、铁基粉末冶金工业当前发展的趋势铁基粉末冶金在机电制造业中的应用具有两个特点:一是它可以制成具有特殊性能的材料,如含油轴承,利用它的多孔性能可以起到自润滑作用;二是它可以大大提高经济效益。因粉末冶金简化了生产工序,属少无切削加工,提高材料利用率,减少工时,节省机床,缩短生产周期,降低成本。特别是一些复杂、异形,加工难度大的制件经济效益尤为突出。
First, the current trend of iron-based powder metallurgy industry development Iron-based powder metallurgy in the electromechanical manufacturing applications has two characteristics: First, it can be made with special properties of materials, such as oil-bearing, the use of its porous properties can play To the role of self-lubricating; Second, it can greatly improve economic efficiency. Because PM simplifies the production process, is less no cutting, improve material utilization, reduce working hours, save machine, shorten the production cycle and reduce costs. In particular, some complex, special-shaped, difficult processing of parts of economic efficiency is particularly prominent.
