Abstract
An abrading tool (10) particularly well adapted for abrading rubberized components. The tool (10) comprises a hardened steel substrate (12) having a matrix bonding layer (14) thereover. A plurality of hard particles (18) are disposed at least partially within the matrix bonding layer (14). An outer coating (20) of a hard refractory material is deposited simultaneously about the hard particles (18) and matrix bonding layer (14) by utilizing either a physical or chemical vapor deposition technique. The outer coating (20) increases the abrading characteristics and longevity of the tool (10).
