摘要： A method for forming an abrasive article via an additive manufacturing technique including forming a layer of powder material comprising a precursor bond material and abrasive particles, compacting at least a portion of the layer to form a compacted layer, binding at least a portion of the compacted layer and repeating the steps of forming, compacting and binding to form a green body abrasive article.

摘要： An abrasive article can include a substrate, abrasive particles coupled by a bond material to the substrate, and a coating overlying at least partially the exterior surface of the bond material. The coating can be a poly(p-xylylene) polymer applied via vapor deposition and may provide enhanced strength to the bond material and extended life time to the abrasive article.

摘要： A bonded abrasive article can include a body including a bond material, abrasive particles contained within the bond material, and pores contained within the body. At least a portion of the pores of the body can include a coating. In one aspect, the coating can be a poly(p-xylylene) polymer applied via vapor deposition. The coated abrasive body can maintain a high permeability and pore volume after coating, and the coating can provide an increase in flexural strength and corrosion resistance to the abrasive article, thereby greatly enhancing its life time.
