摘要： Improved compositions and processes for zincating magnesium and magnesium alloy substrates. An aqueous zincating composition having a pH of from about 8 to about 11 and including zinc ions, a complexing agent, fluoride ions and a reducing agent. A non-electrolytic process for zincating a magnesium or magnesium alloy substrate, including immersing the substrate in the non-electrolytic aqueous zincating composition for a time sufficient to deposit a zincate on the substrate. A non-electrolytic process for zincating a magnesium or magnesium alloy substrate, including preparing a aqueous non-electrolytic composition comprising zinc ions, a complexing agent, fluoride ions and a pH in the range from about 8 to about 11; adding to the composition an amount of a reducing agent sufficient to improve deposition of zincate on the magnesium or magnesium alloy substrate; and immersing the substrate in a composition for a time sufficient to deposit the zincate on the substrate.
