Abstract: This article has described and analyzed the relationship between metal surface and coating materials base on the corrosion mechanism of metals, and it also gave the current status of pretreatment. It further described the prospective development of phosphate-free and chromium-free zirconium-based pretreatment technologies treatment and silane treatment, as well as the low-temperature plasma treatment technology.

Key words: metal surface, pretreatment, metal protection, phosphating, zirconium-based treatment, silane treatment, plasma treatment
