在含有NiSO4·6H2O240g/L、NiCl2·6H2O45g/L、H3BO330g/L、Na2SO420g/L、CTAB0.4mg/L和MoS25g/L的镀液中,通过调整复合电镀参数制备了MoS2梯度复合镀层。研究了不同参数下,所得复合镀层的结合强度。结果表明,复合梯度镀层的结合强度均大于均匀镀层。采用电流密度3A/dm2、搅拌速率350r/min、温度35°C的工艺初镀10min,然后逐渐调整电镀参数到电流密度11A/dm2、搅拌速率600r/min、温度55°C再镀10min,得到的梯度复合镀层的结合强度最大,为41N,是均匀镀层的2倍。
The MoS2 gradient composite coating was prepared by adjusting the composite plating parameters in a bath containing NiSO4 · 6H2O240g / L, NiCl2 · 6H2O45g / L, H3BO330g / L, Na2SO420g / L, CTAB0.4mg / L and MoS25g / The bonding strength of the resulting composite coating was studied under different parameters. The results show that the bonding strength of the composite gradient coating is greater than the uniform coating. The current density of 3A / dm2, the stirring rate of 350r / min, the temperature of 35 ° C initial plating process 10min, and then gradually adjust the plating parameters to current density 11A / dm2, stirring rate 600r / min, temperature 55 ° C and then plated 10min, The gradient of the composite coating the maximum bonding strength, 41N, is evenly coated 2 times.
