Effect of Preparation Conditions on the Performance of Electrodeposited Mo-Ni Coating

Abstract:

Mo-Ni coatings were prepared on Ni alloy by electrodeposition method. The effects of electrodeposition temperature, current density, stir speed and electrodeposition time on deposition rate and microhardness of Mo-Ni coating were researched, respectively. Deposition rate of Mo-Ni coating decreases with the increase of electrodeposition temperature in 35 °C ~ 60 °C. Deposition rate and microhardness of Mo-Ni coating increases with the increase of current density respectively in 15 A/dm² ~ 17.5 A/dm². Deposition rate and microhardness of Mo-Ni coating decreases with the increase of stir speed respectively in 200 r/min to 400 r/min. Deposition rate and microhardness of Mo-Ni coating decreases with the increase of electrodeposition time respectively in 30 min ~ 40 min. When electrodeposition parameters: temperature 35 °C, current density 17.5 A/dm², stir speed 200 r/mi, pH 5 and time 30 min, deposition rate and microhardness of Mo-Ni coatin are as high as 0.269 mg/ cm²·min and 502.4 HV respectively.
