Jan 01, 2013 · Companies such as Keronite (UK), Magoxid-coat (Germany) and Micro-plasmic (USA) have also developed commercial applications of MAO coatings for the improvement of corrosion resistance properties of Mg alloys. As a fascinating technology, MAO is attracting increasing attention from both academic institutions and many industries. The Corrosion Resistance Mechanism of Fe-Based Jun 08, 2020 · To improve the corrosion resistance of Q235 carbon steel in 3.5 wt.% NaCl solution, an Fe-based amorphous coating was deposited on the surface of Q235 carbon steel by detonation gun (D-gun) spraying method. It was found that the coating showed a typical amorphous phase with hardness of about 850 Hv. The morphology of the microdomains showed that the coating was dense, contained no US4329402A - Micro-throwing alloy undercoatings and Novel micro-throwing alloy undercoatings, multi-layer coatings containing a novel micro-throwing alloy undercoating and method of improving the corrosion resistance of ferrous metal articles are provided in accordance with the invention. The novel micro-throwing alloy undercoatings are applied as an initial layer over ferrous metal and comprise a layer of alloy having micro-throwing power
Numerous surface treatments have been elaborated to improve the corrosion properties and biocompatibility of magnesium based alloys, such as chemical conversion coating, electrochemical treatment, organic coating and micro-arc oxidation (MAO). 2224 Micro-arc oxidation is an environment friendly technique to prepare uniform coatings with excellent adhesion and corrosion resistance.
