Hard chrome (Cr+6) provides hardness, corrosion protection and a low coefficient of friction for aircraft landing gear. However, hard chrome plating baths have to meet strict regulations from both the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA). OSHA may limit Cr+6 to .05, which will require more equipment and expense for the plater. New high-tech materials may be a better way to handle aircraft parts.
