Fabrication of micro-textured and plateau-processed functional surface by angled fine particle peening followed by precision grinding

Abstract To fabricate novel micro-textured surfaces with valleys, dimples and plateaus as well as patterned composition as a strategy to improve surface characteristics, we combine fine particle peening (FPP) and precision surface grinding. Combined with a shallow angled FPP to form self-patterned ridge texture on aluminium surface, precision surface grinding with the specific conductive-bonded wheel removes the ridge peaks and simultaneously deposits Cu on the valleys by reducing Cu ions which are condensed in the grinding fluid. The series of those methods are the promising way to create well-processed surfaces which can be applied to tribological and biological devices.
