2. Modeling wear by extruding peripheral burrs

We described the mechanism of wear by extrusion of peripheral burrs in § 1.2 of the article [TRI501] . For a hard counterpart A, whose vertical roughness amplitude is an order of magnitude smaller than that of the softer part B, the roughness of part B undergoes, over a very small thickness, slow plastic deformation of the creep type (figure 1 ), which leads to the formation and development of fine burrs on the edges of the micro-contacts. The detachment of...
