Study on Hardness and Microstructure of Ni-Co Electroplated Coatings AITranslate
Abstract AITranslate
The effects of current density, bath temperature and pH value on hardness of Ni-Co alloy coatings were investigated with single variable method in sulfate system. The optimal technological conditions were determined as follows： the bath temperature is 45 ℃ ,pH value is 3, and the current density is 6 A/dm2. Under these conditions, the Ni-Co alloy coatings with high hardness and good bonding properties on the CuCrZr matrix were prepared. The influences of annealing temperature on hardness and texture of Ni-Co alloy coatings were analyzed. The results show that with the increase of the annealing temperature, the hardness of the coatings increases firstly and then decreases,and the highest HV0.05value reached 506.2 at 300 ℃. After annealing,the coatings exhibits a strong （111） texture.
