The Effect of Surfactant Properties on Lapping Behavior of Materials

Abstract

This paper describes the effect of the polarity of the surfactant on lapping behavior such as stock removal and the amount of minute powders adhered to or embedded in the lapping surface which arise out of the lapping plate and the workpiece. Brass, steel, glass and other materials are lapped by surfactants with different polarity and varied lapping plates. The following experimental results are confirmed : Most anion surfactants appear to be better mediums than cation or nonion surfactants for preventing any adhesion of the minute powders and increasing stock removal. When the silver surface is lapped by using fine aluminium oxide abrasive grains in n-dodecyltrimethyl-ammonium chloride solution (cation) on the glass lapping plate, it is highly resistant to wear, but the rigid glass lapping plate wears out.
