摘要: Abstract In this experimental study periodic line-like patterns with different periodicities (5, 9 and 18 µm) were fabricated by laser-interference patterning on stainless steel samples (AISI-304) 100 Cr 6 balls. Linearly reciprocating dry sliding tests a ball-on-disk configuration performed patterned pairs patterned-substrate/unpatterned-ball Alignment effects studied means of newly developed positioning method, which ensures an optimal alignment. The number cycles was set to 200 20,000 the run-in stability behaviour surfaces, all exhibited lower kinetic coefficient friction than unpatterned reference. Depending respective alignment, wear mechanisms can be distinguished. Differences in real contact area, possibility store particles time needed remove native or laser-induced oxide layer well correlated temporal evolution friction.
