摘要
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。
Ni-MoS2 gradient composite coatings were prepared from a bath containing NiSO4·6H2O 240 g/L,NiCl2·6H2O 45 g/L,H3BO3 30 g/L,Na2SO4 20 g/L,CTAB 0.4 mg/L,and MoS2 5 g/L by adjusting the composite plating parameters,and their adhesion strengths were studied.The results indicated that the adhesion strengths of all composite gradient coatings are higher than that of a uniform coating.The gradient composite coating with the highest adhesion strength of 40 N,which is double that of the uniform coating,can be obtained in the following way：the composite plating is conducted initially at temperature 35 °C,current density 3 A/dm^2,and stirring rate 350 r/min for 10 min,and then continued with gradually adjusted parameters,with the final values of temperature 55 °C,current density 11 A/dm^2,and stirring rate 600 r/min for 10 min.
