锌镍合金电镀在金属制品行业应用探讨

Inquiring into the Application of ZnNi Alloy Electroplating toSteel Wire Products Industry

为进一步提高钢丝在各种恶劣环境下的耐腐蚀性能，延长其使用寿命，研究了钢丝电镀锌镍合金工艺和性能。结果表明：镀层中镍含量在１２％～１５％之间时，其镀层钢丝的耐蚀性最好，为锌镀层的３～６倍，镀层经钝化处理后，耐蚀性更好；经反复弯曲、缠绕试验镀层无起皮剥落现象，表明镀层与基体结合牢固，镀层表面结晶细致，银白光亮，可成为镀锌钢丝的又一替代品。建议在钢丝连续电镀生产线上做进一步的中试研究工作，在制品行业推广应用。

In order to further improve corrosionresisting property of steel wire in every adverse circumstances and prolong its use life,the technology and plating property of ZnNi alloy electroplating for steel wire have been studiedResults show that when Ni content in plating is 12%～15%,the corrosionresisting property of plated steel wire is the best,which is 3～6 times as that of Zn platingThe property will be much better if the plating is passivatedThe plating has no peeling phenomenon in winding and binding test,which indicates that the plating combined with basal body firmlyThe surface crystallization of plating is careful and brightThis kind of steel wire can become a new substitute of galvanized steel wireIt is advised that further middletest research of this kind of electroplating technology in continuous electroplating production line of steel wire can be done continuously so as to spread and apply to steel wire products industry
