粉末冶金材料在工业上已经大量采用,在蒸汽机车上使用铁基粉末冶金减摩材料已有十几年的历史了,据不完全统计,全路已有50％以上的蒸汽机车使用粉末冶金填料。为了进一步提高产品质量,推广使用,铁道部科学研究院机辆所于1981年9月份与北京粉末冶金一厂签订了粉末冶金在机车车辆上应用的技术协议,双方共同进行调研与试验。 Powder metallurgy materials have been widely used in industry. The use of iron-based powder metallurgy anti-friction materials for steam locomotives has been more than ten years. According to incomplete statistics, more than 50% of the locomotives have used powder metallurgy stuffing . In order to further improve the quality of products, promote the use of the Ministry of Railways Institute of Science and Technology in September 1981 with the Beijing Powder Metallurgy Plant signed a powder metallurgy technology agreement on the rolling stock, the two sides carried out research and experimentation.
