摘要： The present disclosure relates to abrasive articles including an abrasive member having opposing major surfaces, a working surface and an exterior attachment surface, wherein the abrasive member comprises an inorganic material having a Mohs hardness greater than about 7.0; and a magnetic member, having opposing first and second major surfaces and a corresponding magnetic force, wherein the first major surface of the magnetic member faces the exterior attachment surface. The abrasive articles of the present disclosure may include a third member. The third member is attached to the magnetic member by a magnetic force. The abrasive member with attached magnetic member is designed to be easily removed from the third member. Methods of separating an abrasive member from an abrasive article and replacing the abrasive member of an abrasive article are also provided.

摘要： The disclosure relates to fixed abrasive articles having a plurality of three dimensional abrasive composites including abrasive particles dispersed in a matrix material including a polymeric binder and a plurality of nanoparticulate inorganic filler particles having a volume mean diameter no greater than 1000 nanometers (nm). In some embodiments, the volume mean diameter of the abrasive particles is less than 500 nm, and the volume mean diameter of the inorganic filler particles is no greater than 200 nm. In other embodiments using non-ceria abrasive particles, the ratio of the amount of matrix material to the amount of non-ceria abrasive particles on a volumetric basis is at least 2. In alternate embodiments using non-ceria abrasive particles, the ratio of the amount of non-ceria abrasive particles to the amount of inorganic filler particles on a volumetric basis is no greater than 3. Also provided are methods of making and using fixed abrasive articles according to the disclosure.

摘要： A polishing solution containing two different organic acids is described. The first organic acid is a multifunctional amino acid. The second organic acid is selected from a simple carboxylic acid, a hydroxy-carboxylic acid, and combinations thereof. The simple carboxylic acid may be a monofunctional or a multifunctional simple carboxylic acid. Polishing solutions containing two different organic acids providing enhanced removal rates are also described. Methods of polishing surfaces, including metal surfaces comprising copper, are also described.
