But when the grinding tool was subjected to ultrasonic vibration, the pits on the machined surface were significantly reduced (Fig. 14d). When A l = 11 μm was applied, h max was reduced to 8.18 μm. Obviously, the mechanism of UAG to improve the quality of machined surface is that h max is reduced by the ultrasonic vibration of grinding tool.
The ultrasonic vibration device was mounted on the grinding machine platform and then the tangential ultrasonic vibration along the grinding direction was applied on one end of workpiece (Fig. 2b).

Passivation is a widely-used metal finishing process to prevent corrosion. In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer, or passivation film, that is less likely to chemically react with air and cause corrosion.
