Abstract AITranslate

Ni-Co/ZrO2 composite coatings were prepared by ultrasound-assisted electroplating in the system of sulfamate bath. The effects of current density, concentration of ZrO2 particles and ultrasonic power on hardness of Ni-Co/ZrO2 composite coatings were investigated with single variable method. The process pa- rameters of Ni-Co/ZrO2 composite electrodeposition were optimized. The coatings were tested by nanoin- dentation,and the morphology and composition of the optimized composite coatings were characterized by field emission scanning electron microscopy. The research results show that the optimized technological conditions are as follows:cathode current density of 5 A/dm2 , ZrO2 particle concentration of 10 g/L, ultrasonic power of 240 W. Under these conditions, the nanohardness, elastic modulus and the ratio of nanohardness to elastic modulus are up to 6.13 Gpa,291 Gpa and 0. 021 ,respectively. Furthermore,the coating is flat and compact,and ZrO2 nanoparticles are well eomposited in metal matrix.
