Abstract
The production amount of sintered P/M parts have been increased year by year, because of their good productivity for the parts with complicated shape, and their good flexibility for material design. However, after 1993, the increase ratio of P/M production in Japan have shown a drop by business recession. Under such serious condition, more studies and developments are needed in order to expand the use of P/M parts. In this report, we introduce a few topics that P/M parts will be given higher quality and cost performance, and suggest the necessity of activating R&D on P/M parts for automotive applications from user's point of view.
