- 摘要:
- 针对镍钴镀层抗拉强度不能满足工业需求的问题,为改进氨基磺酸盐镀液的电镀工艺,采用电化学工作站、电子万能试验机、显微硬度计、 X 射线衍射仪( XRD )、扫描电镜( SEM )等测试方法,设计正交试验,研究温度、主盐浓度和电流密度等因素对电镀反应极化曲线、电化学动力学参数、电镀层抗拉强度、硬度、晶体结构及表面形貌等性质的影响;通过对抗拉强度进行正交和单因素分析,优化得到了最佳实验方案。结果表明:镍盐浓度对电极交换电流密度 j0有显著正影响,相应 j0值范围是 0.002 mA/dm 2 ~1.640 mA/dm 2 ;钴盐浓度对析氢副反应有负影响,可降低析氢效率至 0.3% ;工艺因素对于抗拉强度和硬度的影响程度分别是:温度>钴盐浓度>电流密度>镍盐浓度和温度>电流密度>钴盐浓度>镍盐浓度;优化结果:当氨基磺酸镍 400 g/L 、氨基磺酸钴 30 g/L ,温度为 50 ℃ ,电流密度为 3 A/dm 2 ,其抗拉强度达到 853 MPa ,维氏硬度为 234 HV ;温度对氨基磺酸盐电镀体系的性能和镀层质量有显著影响,温度升高时引起镍钴镀层的晶粒由( 200 )择优取向转为( 111 )和( 220 )生长。
- Abstract:
- : Aiming at the problem that the tensile strength of nickel-cobalt coating cannot meet the industrial demand , in order to improve the electroplating process of sulfamate plating solution , the orthogonal test was designed by using electrochemical workstation , electronic universal testing machine , microhardness tester , XRD , SEM and other test methods. The effects of temperature , main salt concentration and current density on the polarization curve of electroplating reaction , electrochemical kinetic parameters , tensile strength , hardness , crystal structure and surface morphology of electroplating layer were studied. The optimal experimental scheme was obtained by orthogonal and single factor analysis of tensile strength. The results show that the nickel salt concentration has a significant positive effect on the electrode exchange current density j0, and corresponding j0 range is 0.002 mA/dm 2 ?1.640 mA/dm 2 ; the concentration of cobalt salt has a negative effect on the side reaction of hydrogen evolution , which can reduce the hydrogen evolution efficiency to 0.3%.The influence degree of processfactors on tensile strength and hardness is as follows : temperature > cobalt salt concentration > current density > nickel salt concentration and temperature > current density > cobalt salt concentration > nickel salt concentration.The optimization results are as follows : nickel sulfamate 400 g/L , cobalt sulfamate 30 g/L , temperature 50 °C , current density 3 A/dm 2 , tensile strength 853 MPa , Vickers hardness 234 HV ; the temperature has a significant effect on the performance of the sulfamate electroplating system and the quality of the coating. When the temperature increases , the grain of the nickel-cobalt coating changes from ( 200 ) preferred orientation to ( 111 ) and ( 220 ) growth.
