The present authors recently found an interesting phenomenon in a glass lapping test with a silver lapping plate and n-dodecyltrimethylammonium chloride solution (as cation surfactant) that the silver was almost not worn by the lapping even under the condition of large stock removal of glass. Since it was observed only in some limited experiments by using fine aluminum oxide abrasive grains with a vibration lapping apparatus, here the authors examine experimentally the effect of the kinds of abrasive grains on the glass lapping behavior, and also check whether it depends on the types of testing apparatus or not. From the results of experiments performed by using several kinds of abrasive grains with two different types of testing apparatus, i. e. , vibration-type and sliding-type machines, it was confirmed that the silver surface possesses high wear-resistance irrespective of the lapping apparatus and used abrasive grains. The high wear-resistance of silver is attributed to adhesion of minute powder particles.
