改善粉末冶金产品的质量,提高其技术水平、可靠性和耐用性,这些现实问题同检查其性能的标准方法是分不开的。为了评价大量生产条件下所用的检验金属粉末和烧结制品质量的验收方法标准化的情况,我们整理了国内三十多个主要粉末冶金企业的资料。粉末冶金结构零件、减摩零件、电工制品、过滤元件和金属粉末质量检测方法标准化的资料列于表1和表2。这些资料于一九七七年三月,在苏联部长会议科学技术国家鉴定委员会“普通和特殊 Improving the quality of powder metallurgy products, improving their technical level, reliability and durability are all inseparable from the standard methods of checking their performance. In order to evaluate the standardization of acceptance methods for testing the quality of metal powders and sintered products used under a large number of production conditions, we have compiled information on more than 30 major powder metallurgy companies in China. Materials standardized for powder metallurgy structural parts, anti-friction parts, electrical products, filter elements and metal powders are listed in Table 1 and Table 2. These materials in March 1977, at the Soviet Council of Ministers of Science and Technology Appraisal Committee, "ordinary and special
