“…The phosphate–permanganate conversion coatings have been shown to have corrosion resistance comparable to chromate treatments. The research on phosphate–permanganate treatment of Mg–Li alloys 163 using a solution containing sodium phosphate and potassium permanganate has shown that a non-powdery, homogeneous and uniform coating can be achieved. The pH and phosphate concentration of the conversion solution were the most effective on the quality of the final coating.…”

Magnesium-lithium base alloy is one of the lightest metallic engineering materials with a density of 1?35-1?65 g cm 23 , which is referred to as superlight materials. It has become an attractive material in the fields of aerospace, automobiles, portable electronics, etc. In this paper, the developing history and recent progress of superlight magnesium-lithium base alloys are reviewed. The progress on molten electrolysis preparation, processing technologies and surface processing technologies are introduced, and future research directions are suggested based on the current research progress.

“…28 However, the stringent environmental restrictions on the use of Cr(VI) bearing systems have necessitated development of chrome free coatings. Phosphate-permanganate based anodising/coating systems have emerged as attractive alternatives, 26,28,30,31 and have been successfully employed on large automotive components. 28 Anomag is an improved phosphate-permanganate method, with carefully chosen process steps, conditions, and formulations (such as interprocess cleaning solutions, pH, temperature and time).…”
