Abstract

The wear resistance of diffusion coatings in conditions of specific pressures of 3, 7 and 10 MPa was studied. The boride coatings were prepared by means of diffusion methods using C45 steel as the substrate material. Research on the microstructure and redistribution of chemical elements on wear surface of a borided layer was carried out. It was found that the boride coatings should be used under a specific pressure of 7 MPa. It was found that the wear of friction couple coating of steel C45 under specific pressure of 3 MPa proceeds according to the oxidation wear mechanism, while under specific pressures of 7 and 10 MPa the abrasive wear prevails. The wear-induced segregation of atoms in coatings was studied using secondary mass-spectroscopy method (SIMS). Increased C, O, and B concentrations were noticed at the wear surface on depth from 50 to 2000 Å. The secondary wear-induced structure formation on the wear surface resulted in high wear resistance of diffusion borided coatings.

摘要

研究了扩散涂层在3、7和10MPa特定压力条件下的耐磨性。以C45钢为基底材料，通过扩散法制备硼化物涂层。对硼化层磨损表面的微观结构和化学元素再分布进行了研究。结果发现，硼化物涂层应在7MPa的特定压力下使用。结果发现，C45钢摩擦副涂层在3MPa特定压力下的磨损按氧化磨损机制进行，而在7和10MPa特定压力下，磨粒磨损占主导。采用二次质谱法（SIMS）研究了涂层中磨损诱导的原子偏析。在磨损表面深度为50至2000Å处，发现C、O和B浓度增加。磨损表面上二次磨损诱导的结构形成导致扩散硼化涂层具有高耐磨性。
