为研究刷镀电压对镍镀层摩擦磨损性能的影响,分别在不同刷镀电压下,采用快速镍刷镀方法在45#钢表面制备工作层.在球-盘摩擦磨损试验机上,以Cr12钢球为摩擦配副进行油润滑条件下的摩擦磨损试验,通过磨损失重、油液的光谱和铁谱分析、摩擦系数、磨损表面形貌研究了不同镍镀层的摩擦磨损性能.结果表明:不同刷镀电压下制备的镍镀层的摩擦磨损性能存在较大差异.刷镀电压过低(8V)或过高(22V)时,镍镀层耐磨性能均下降;当刷镀电压为14V时,镍镀层的摩擦磨损性能最佳;镍镀层磨损机制以磨粒磨损和黏着磨损为主.
In order to study the influence of brushing voltage on the friction and wear properties of nickel coating, the working layer was prepared on the surface of 45 # steel by using a rapid nickel plating method under different brushing voltages respectively.On the ball-disc friction and wear tester, The tribological properties of different nickel coatings were studied by means of friction loss test, wear loss, oil spectrum and iron spectrum, friction coefficient and wear surface morphology. The results show that different brush plating The friction and wear properties of nickel coatings prepared under different voltage are quite different.When the voltage is too low (8V) or too high (22V), the wear resistance of nickel coatings decreases. When the brush voltage is 14V, Friction and wear performance of the best; wear mechanism of nickel coating abrasive wear and adhesive wear-based.
