【Abstract】 This paper mainly deals with the Boron-Zirconizing process of 5CrMnMo steel by pasting method. The experimental results show that the diffusion layer of the specimen possesses higher hardness(1600-1800HVO.1), good red-hard-ness, high wear-resistance and lower brittleness. After treated with this process, the service life of the core push rod of 5CrMnMo steelfor chain making unitmay be prolonged to four times than that with onventionalprocess. Indust-rial practice proved that this process has many advantages, such as convenientfor operation, fair applicability, good reliability, low cost and high economcal efficiency etc.更多还原
