VERFAHREN ZUR OBERFLAECHENBEARBEITUNG SCHIEBENFOERMIGER VERNICKELTER ALUMINIUMSUBSTRATE.

摘要

Method of surface treating Ni-coated Al substrates to produce a polished and texture surface of roughness depth Rt of 0.04-0.1um, a average roughness depth R2 of 0.04-0.1um and an average roughness value Ra of 0.0065-0.0095, consists of lap-polishing both sides of the substrate with a polishing material to remove 2-4um of the surface layer and produce an average roughness value of 0.04-0.06um. Without removing the substrate from the polishing machine, a second process using a polishing material having 3-10 times the grain size is effected to produce an essentially paddle wheel structured texture.
