Nonwoven composite abrasive comprising diamond abrasive particles

摘要

An abrasive article includes a support, a first polymeric binder, a second polymeric binder, and abrasive particles. The support includes a plurality of nonwoven layers. A method of forming an abrasive article includes providing a support including, applying a first coating of the first polymeric binder to the support, applying superabrasive particles to the coated support, applying a layer of a second polymeric binder overlying the superabrasive particles. The method further includes compressing the support and applying heat to cure the first polymeric binder. A method of preparing a work piece includes applying a thermal spray coating to the work piece, and polishing the thermal spray coating with the abrasive article.
