  • SYSTEMS AND METHODS FOR TREATING A SUBSTRATE
    Publication number: 20240158920
    Abstract: Disclosed herein is a system for treating a magnesium or a magnesium alloy substrate comprising: a first pretreatment composition comprising a fluorometallic acid and free fluoride in an amount of 10 ppm to 500 ppm based on total weight of the first pretreatment composition and having a pH of 1.0 to 4.0; and a second pretreatment composition comprising a lanthanide series metal, the second pretreatment composition being substantially free of peroxide. Also disclosed are methods of treating a magnesium or magnesium alloy substrate. Treated magnesium and magnesium alloy substrates also are disclosed.
