“…The effect of the magnesium alloy AZ91 microstructure and roughness on the nucleation, deposition rate, coating microstructure, and mechanical properties of the EN coatings was recently investigated (Liu & Gao, 2006). Experimental results show that surface sandblasting pre-treatment (R a = 0.05 µm) enhances the nucleation and coalescence of nickel crystallites.…”

“…Liu showed that the www.intechopen.com presence of an anodic oxide on the AZ91 substrate provides high density of nucleation sites for nickel plating, resulting in the reduction of porosity of the metallic layer and providing better adhesion strength (Liu & Gao, 2006). Zeng proposed the plasma electrolytic oxidation in silicate bath followed by electroless Ni-P deposition.…”

“…It appears that while extensive studies have been carry out on wear of aluminium alloys, no such detailed work has been undertaken regarding the wear of different magnesium alloys. Various techniques developed to improve the tribological behaviour of magnesium alloys through surface hardening or strengthening [4,5]. The study of wear behaviour magnesium alloys reveals that wear rate greatly affected by applied loading and sliding conditions.…”

Study involves the comparison between wear properties of commercially pure Mg, Mg-4Zn, Mg-4Zn-3MnO 2 and Mg-4Zn-3MnCl 2 by addition of Zn and Mn (by changing their sources). The wear behaviour of all systems investigated under applied loads of 5, 10, 15, 20, 25 and 30 N at the room temperature. The wear tests carried out by pin-on-disk type wear testing machine at sliding speed of 0.25 m/s for a total sliding distance of around 452 meter. The result shows that the wear property of pure magnesium improved by addition of 4.0% zinc but by addition of manganese in improvement of wear properties is not noticeable. At lower load condition (5N & 10N) the highest wear resistance obtained in Mg-4Zn-3MnCl 2 system. At higher load (20N, 25N & 30N) wear resistance remain almost equal in all systems (Mg-4Zn, Mg-4Zn-3MnO 2 & Mg-4Zn-3MnCl 2 ).

“…7,8 Considerable effort has been made to improve the wear and anti-corrosion properties of magnesium alloys. Several surface modification techniques [9][10][11][12][13] including chemical conversion, anodic oxidation, microarc oxidation (MAO) treatment, electroplating, electroless plating and physical vapor deposition (PVD), have been used to protect the surface of magnesium alloys.…”

Electrodeposition of Diamond-like Carbon (DLC) Films on Mg by Plasma Electrolysis

Diamond-like carbon (DLC) films were deposited on Mg substrate in CH 3 OH and KNO 3 solution by the liquid-phase electrodeposition technique at ambient pressure and temperature. The applied voltage between the electrodes was low (130 V) due to the use of conductive inorganic liquids. The surface morphology was examined by Scanning Electron Microscopy (SEM). Corrosion performance of the films was investigated by potentiodynamic polararization tests and electrochemical impedance spectroscopy (EIS) in 3.5% NaCl solution. The structure of the films was characterized by X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. Raman spectroscopy analysis of the films revealed two broad bands at approximately 1369.5 and 1554.7 cm bonding, which is also in accordance with the results of XPS spectra. SEM showed that DLC film was uniform, homogeneous but rough. Potentiodynamic polarization curve and EIS indicated the corrosion resistance of the Mg substrate was markedly improved by DLC films. A mechanism for the formation of sp 3 and sp 2 hybridizations is proposed.
