The tribological performances of the SiO₂/MoS₂ hybrids as lubricant additives were explored by a reciprocating ball-on-flat tribometer for AZ31 magnesium alloy/AISI 52100 bearing steel pairs. The results demonstrated that the introduction of SiO₂/MoS₂ hybrids into the base oil exhibited a significant reduction in the friction coefficient and wear volume as well as an increase in load bearing ca...

Cerium conversion coatings are a potential alternative to chromium conversion coatings for improving the corrosion resistance of magnesium alloys. This study detailed the microstructure and corrosion resistance of cerium conversion coatings on AZ31 magnesium plates treated in 0.05 kmolm 3 cerium nitrate solution, with and without 0.25 kmolm 3 hydrogen peroxide. The results indicate that the cor...

Mg-based metallic materials have been making continuing progress as vascular stents. However, the research of Mg-based materials as non-vascular stents is still at its primary stage. AZ31 stents hereby were implanted into the common bile duct of rabbits for 6 months. The results revealed an existence of 93.82 ± 1.36% and 30.89 ± 2.46% of the original volume after 1 and 3 month, respectively. Wh...

Abstract In this work, corrosion of the AZ31 magnesium alloy was examined in 0.05 M NaCl solutions containing 0.01–0.150 mol/dm 3 potassium permanganate as a inhibitor. A set electrochemical impedance spectroscopy, linear sweep voltammetry, and hydrogen evolution measurements revealed high inhibitor effectiveness at relatively (0.150 ) KMnO 4 concentrations. Based on data energy-dispersive X-ra...
