TREATMENT OF PARTS WITH METALLIZED FINISH AREAS WITH A DIFFERENTIATED APPEARANCE

摘要

The invention relates to a process for the treatment of parts for creating a surface with areas with shiny and matte appearances, in which on the surface previously coated with a first layer of copper and a second layer of metal a selective etching of the second layer is performed, wherein the selective etching of the second layer is performed according to the area or areas to be glazed with respect to the rest of the part. The process allows a finish with areas of a different shine (from mirror shine to matte), the differences in thickness of which cannot be observed by the human eye without optical aids.
