Super Coatings for Superabrasives

While superabrasives in grinding wheels generally perform better than conventional abrasives, the grains also possess characteristics that can lead to unwanted chemical reactions during the wheel manufacturing process or premature pullout during use. This article discusses the ways a coating applied to the grains can reduce or prevent these undesirable side effects. .
