We study the wear resistance of the disks of furrow-openers of seeding machines. The surface nanocrystalline structure of the disks made of 65G steel is formed by the mechanical-pulse treatment under the conditions of dry abrasive friction. It is shown that, in the tests with nonfixed and fixed abrasives, the procedure of surface nanostructuring makes the wear resistance of steel 5.4 and 8.8 times higher, respectively, than in the initial state. The thermal treatment of steel prior to its surface nanostructuring considerably increases its wear resistance in the tests with fixed abrasives.

65G钢的表面纳米结构对播种机开沟器圆盘耐磨性的影响

我们研究了播种机开沟器盘的耐磨性。由65G钢制成的磁盘的表面纳米晶体结构是在干磨擦摩擦条件下通过机械脉冲处理形成的。结果表明，在用非固定和固定磨料进行的测试中，表面纳米结构化程序使钢的耐磨性分别比初始状态高5.4倍和8.8倍。在使用固定磨料进行的测试中，对钢进行表面纳米结构化之前的热处理会大大提高其耐磨性。
