摘要
分析影响齿轮和销轴盐浴氮碳共渗后畸变的因素。通过盐浴氮碳共渗试验,发现盐浴中氰酸根(CNO-)含量的变化造成渗层组织的不同,引起零件尺寸的变化。把CNO-的含量控制在限定范围内,可以有效控制畸变。
Factors that influenced the distortion of gears and pins during salt bath nitrocarburizing were analysed.Through salt bath nitrocarburizing,it is found that variety of CNO-content in salt bath causes different microstructure in nitrocarburized layer,thus result in obvious change of parts dimension.By controlling the content of CNO-within provided limits,the distortion of gears and pins can be controlled effectively.
