为提高镀铁层的硬度和耐磨性,采用了正交实验的方法研究了镀液中碳化硼的浓度、粒度和氯化亚铁的浓度对镀层硬度及耐磨性的影响。结果表明:影响镀铁层耐磨性的因素主次顺序为:B4C浓度>B4C颗粒度>FeCl2·4H2O浓度;镀铁工艺的优水平为B4C颗粒度1200目、B4C浓度30g/L、FeCl2·4H2O浓度350g/L;影响镀层显微硬度的因素主次顺序为B4C浓度>B4C颗粒度>FeCl2·4H2O浓度。
In order to improve the hardness and wear resistance of the iron coating, the effects of boron carbide concentration, particle size and ferrous chloride concentration on the hardness and wear resistance of the coating were studied by orthogonal experiment. The results show that the main order of the factors that affect the wear resistance of the coating is: B4C concentration> B4C particle size> FeCl2 · 4H2O concentration. The optimum level of iron plating process is 1200 mesh B4C, 30g / L B4C, 4H2O concentration of 350g / L; primary and secondary factors affecting the microhardness of the coating were B4C concentration> B4C particle size> FeCl2 · 4H2O concentration.
