Aluminum Composite Coating from Dimethylsulfon Baths

Titanium-Aluminum Oxide Coating on Aluminized Steel

In this study, a plasma electrolytic oxidation (PEO) process was used to form titanium-aluminum oxide coating on aluminized steel. The present work was mainly to study the effects of treatment time of PEO process on properties of the titanium coating. A potentiodynamic polarization corrosion test was employed to investigate the corrosion resistance of the coating. The friction coefficient and w...

Mechanical Behavior of Aluminum (AlSi10Mg)-RHA Composite

Rice Husk Ash (RHA) of three different particle size ranges (50 – 75 μm), (75 – 100μm) and (100 – 150μm) in 3, 6, 9 and 12 % by weight was reinforced with the aluminium alloy using stir cast route. The microstructure and mechanical properties of the fabricated composites were analyzed. The results reveal that the tensile strength, compressive strength and hardness of the aluminum alloy composit...

Trivalent Chromium Conversion Coating for Corrosion Protection of Aluminum Surface

Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...

Acid aluminum phosphate for the binding and coating of materials

This is a review of acid aluminum phosphate for the binding and coating of materials. The acid aluminum phosphate in the form of a solution obtained by dissolving aluminum hydroxide in phosphoric acid, with a P/Al molar ratio of 23, is effective for the binding of fibrous or particulate materials. Porous ceramic articles are made using this binder by wet forming, followed by heat treatment. The...
