Research Progress of Magnesium Potassium Phosphate Cement-Based Anti-Corrosive Coating on Steel Substrate
Year: 2025
Type: article
Abstract: Magnesium potassium phosphate cement (MKPC)， as a new type of inorganic cementitious material， shows the characteristics of fast setting speed， high early strength， dense structure， and good wear resistance.Employing magnesium potassium phosphate as a binder，modified by additives，mineral admixtures and composite modification methods，metal protective coatings with excellent anti-corrosion properties can be obtained， which are mainly used for corrosion protection of steel surfaces.This paper reviewed the hydration and anti-corrosion mechanisms of MKPC-based coatings， examining the influence of material composition and mix design on their protective performance.In particular，the modification approaches for MKPC-based anti-corrosive coatings were discussed， with their application techniques and performance evaluation methods being comprehensively documented.Furthermore， prospective applications of MKPC-based coatings in corrosion protection were critically evaluated.
