Effect of Ultrasonic on Grain Density of Electroplated Diamond Tools

Abstract

Coating quality and electroplating efficiency can be improved by application of ultrasonic agitation. The nickel coatings and electroplated diamond tools were fabricated. The effects of ultrasonic agitation on tool fabrication processes were analyzed. Cathode polarization curves and coating hardness were measured. Diamond grains on tool substrate were observed with microscope. Alumina grinding experiments were carried out and grinding ratios were calculated. Experimental results show that cathode polarization …
