A Study on the Chrome Platability of Cast Aluminum Wheels

A detailed analysis of maximum aluminum substrate porosity for chrome platability of low pressure permanent mold(LPPM) wheels has been performed in a controlled environment. This includes a porosity comparison of different wheel casting processes, results of a laser drilled aluminum wheel section (providing verification of the real world information), results of several design of experiments (DOE) trials to determine critical LPPM casting variables and successful chrome platiblity of LPPM wheels without copper buff.
