Corrosion Resistance of the Superhydrophobic Mg(OH)2/Mg-Al Layered Double Hydroxide Coatings on Magnesium Alloys

Coatings of the Mg(OH)2/Mg-Al layered double hydroxide (LDH) composite were formed by a combined co-precipitation method and hydrothermal process on the AZ31 alloy substrate in alkaline condition. Subsequently, a superhydrophobic surface was successfully constructed to modify the composite coatings on the AZ31 alloy substrate using stearic acid. The characteristics of the composite coatings wer...

Current Research Status of Corrosion Resistant Coatings

The recent patents on corrosion resistant coatings were reviewed in this paper. The materials of corrosion resistant components, e.g., metals and alloys, ceramics, polymers as well as composite materials, developed for environmental, economic and other concerns were discussed. In addition, the novel methods for forming the coatings, including the powder floating by vibration and the precursor g...

Development of Corrosion Resistant Zn-Ni-TiO2 Composite Coatings

The Zn-Ni-TiO2 composite coatings were developed on mild steel by electrodeposition method. The bath constituents (ZnSO4.6H2O, NiSO4.6H2O, TiO2, thiamine hydrochloride) and operating conditions (temperature and pH) were optimized by Hull cell method, for peak performance of the coating against corrosion. The coatings were prepare...
