摘要
螺旋卸车机绞龙叶片由于长期工作在煤炭中，其表面很容易受到磨损和腐蚀，严重阻碍了其使用寿命。在盐浴共渗条件下对获得的叶片进行低温处理，以获得更好的绞龙叶片表面。通过改变低温处理时间获得不同的低温处理试样，利用洛氏硬度仪测试了试样表面硬度，分析实验结果，找出硬度变化规律，优化盐浴共渗和低温处理工艺方法，为实际工程应用提供理论和技术支持。
The auger blades of the spiral unloading machine was worked in coal for long time. Its surface is easily to wear and corrosion, and life was severely hampered. In order to get a better auger blade surface, the blades were given a low tem- perature process after the salt bath nitriding. The samples of different low temperature were gotten by changing the cryogenic processing time in this article. The hardness of the sample sur{ace was tested by the rockwell hardness tester. The cryogenic treatment process was optimized. It will provide theoretical and technical support for the practical application.
