| Abstract |
| A typical brightener-propargyl alcohol-was added to enhance the cutting performance during Ni-diamond composite electrodeposition. Electrochemical analysis was performed and mechanical properties such as hardness and wear resistance were examined. In addition, the surface morphology of composite coating layers was observed using an optical microscope, and using image analysis software, the dispersivity of the diamond particles was analyzed to calculate the number of single diamond particles. A galvanostatic test was employed to identify the electrodeposition mechanism as a function of the concentration of propargyl alcohol. When 0.1 mg/ℓ of propargyl alcohol was added, the dispersivity and adhesion performances of the Ni-diamond coating layer were optimized for cutting tools. (Received September 22, 2015) |
