拖拉机由于工作环境灰尘大,要求易损件有良好的抗磨料磨损的特性,并希望在运转中零件能尽量保持良好的润滑条件,以期达到较长的使用寿命。为了加速实现我国的农业机械化,更要求在生产中不断采用新工艺和经济的制造方法,因此,粉末冶金零件在拖拉机上的应用是十分有价值的。为了大力推广这一新技术,本文对粉末冶金零件的特性、工艺和我国这方面的研究、生产及应用作一扼要叙述。
Due to the heavy dust in the working environment, the tractor needs the wearing parts to have the good anti-abrasion and wear characteristics, and hopes the parts can try their best to maintain the good lubrication condition in operation so as to achieve a longer service life. In order to accelerate the realization of agricultural mechanization in our country, it is also required to continuously adopt new techniques and economical manufacturing methods in production. Therefore, the application of powder metallurgy parts on tractors is very valuable. In order to vigorously promote this new technology, this article makes a brief account of the characteristics of the powder metallurgy parts, technology and research, production and application in this area in our country.
