ZrO₂-Doped MAO Coating

10× Harder, Wear & Corrosion Resistant

Utilizing an MgF₂ passivation layer to prevent ablation, ZrO₂ nanoparticles re-melt and precipitate as uniformly dispersed nanocrystals, significantly enhancing the hardness and corrosion resistance of MAO coatings on magnesium alloys.
