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.
