| Summary: | 碩士 === 健行科技大學 === 機械工程系碩士班 === 106 === The diamond cutting line is one of the main consumable elements in the green energy industry of the advanced countries. Diamonds have the advantages of high inertness and high hardness. The surface structure is one of the important factors affecting the material properties. Watts nickel plating was used as electroplating techniques with applying different electroplating conditions such as different current density(0.015386 A/dm2,0.017584 A/dm2,0.019782 A/dm2), diamond powder concentration(3g/L,4g/L), diamond surface coating type (Ti,Ni), electroplating time(15 sec,20 sec), additives(Ethylenediaminetetraacetic acid,EDTA), etc.. Diamond particle size was 6~12µm, and brass-plated steel wire (5cm) was used and other controlled plating techniques to form an excellent nickel-diamond composite coating to improve the corrosion resistance and wear resistance of this material, in order to improve the service life of the diamond cutting wire.
In this study, a Potentiostatic and a wet abrasion tester were used to evaluate the corrosion resistance and wear resistance of diamond thin wires under different plating conditions. The optimum conditions were found that the current density was 0.019782 A/dm2, the adding diamond concentration was 4g/L, and the plating time was 20 sec. With the addition of EDTA, the titanium (Ti) diamond thin wire has the best corrosion resistance and wear resistance.
