The effect of diamond powder characteristics on lapping …

In Automotive appliions, sintered Silicon Carbide has been used in appliions such as seal pump faces. The surface of sintered SiC, when lapped or polished for sealing to another surface, must be free of blemishes and mechanical defects. Lapping and polishing processes therefore must be well defined and controlled assuring minimal variation and production scrap. In this study, we related
