在1969～1978年10年中,日本金属成形工业中粉末冶金增长最快。粉末冶金制品包括铁基与铜基粉末冶金结构零件和轴承,摩擦材料,软、硬磁铁氧体及软、硬金属磁性材料。作者根据访日期间见闻,就日本烧结机械零件制造技术的发展,评述了铁粉生产中的VIDOP法,压机与烧结设备,粉末成形技术,烧结锻造和高强度烧结钢。 In the 10 years from 1969 to 1978, Japan’s metal forming industry, the fastest growing powder metallurgy. Powder metallurgy products include iron-based and copper-based powder metallurgy structural parts and bearings, friction materials, soft and hard magnetic ferrite and soft and hard metal magnetic materials. Based on the information during the visit to Japan, the author reviews the VIDOP method, press and sintering equipment, powder forming technology, sintering and forging, and high-strength sintered steel in the production of sintered powder in Japan.
