METHOD FOR APPLYING ABRASIVE PARTICLES TO A SURFACE AND MEMBER THEREFOR ABSTRACT OF THE DISCLOSURE A method for applying preselected abrasive particles to an article surface includes providing an electrically non-conductive tape and particle member for use in an electrodeposition type system. The tape includes pores large enough to allow passage of electrodeposition current and electrolyte solution but smaller than the size of abrasive particles to be retained on the tape. The tape has a porous adhesive layer of relatively low tack level, the adhesive carrying the abrasive particles through a first or relatively weak bond. A metallic coating is eIectrodeposited through pores of the tape and adhesive onto the article surface and about the abrasive particles in contact with such surface. This bonds the abrasive particles to the article surface through a second bond between the metallic coating and the abrasive particles which is stronger than the first, relatively weak bond. Thereafter, the tape and particle member is separated at the first bond from the abrasive particles bonded to the article surface.
