Influence of the addition of SiO2 nanoparticles to a hybrid coating applied on an AZ31 alloy for early corrosion protection
(2016-10-15)
This work aims to investigate the corrosion resistance of AZ31 magnesium alloy protected by hybrid films based on tetraethylorthosilane (TEOS) and (3-glycidoxypropyl)trimethoxysilane (GPTMS) with the addition of different ...
Low temperature rolling of AZ91 alloy for hydrogen storage
(Pergamon-Elsevier Science Ltd, 2017-12)
The hydrogen storage properties of a commercial AZ91 magnesium alloy were investigated after processing by cold rolling in two different conditions: (a) extensive cold rolling at room temperature (CR); (b) rolling with the ...
Corrosion protection of AZ91D magnesium alloy by a cerium-molybdenum coating. The effect of citric acid as an additive
(National Engg. Reaserch Center for Magnesium Alloys, 2018-12)
In order to improve the corrosion resistance of AZ91D magnesium alloy, a coating was formed by a potentiostatic technique from a solutions containing Ce(NO3)3, Na2MoO4 and citric acid (H3Cit). The degree of corrosion ...
Formation of a cerium conversion coating on magnesium alloy using ascorbic acid as additive: Characterisation and anticorrosive properties of the formed films
(KeAi, 2016-12)
Cerium-based conversion coatings were formed on AZ91D magnesium alloy by immersion of the substrate in solutions containing Ce(NO3)3, H2O2 and ascorbic acid (HAsc). The characterisation of the films was performed by ...
Cerium Coatings as an Alternative for Corrosion Protection of AZ91D Mg Alloy for Biomedical Applications
(Nova Science Publishers, 2021)
This chapter is a compilation of investigations related to the formation of cerium coatings onto AZ91D Mg alloy in order to improve its corrosion resistance in simulated body fluid. The films were electrogenerated from ...
Improvement in the corrosion protection and bactericidal properties of AZ91D magnesium alloy coated with a microstructured polypyrrole film
(Elsevier, 2018-11)
In this work hollow rectangular microtubes of polypyrrole (PPy) films were potentiostatically electrodeposited on magnesium alloy AZ91D in salicylate solution. The substrate was previously anodized under potentiostatic ...
Improved Corrosion Resistance of AZ91D Mg Alloy by Cerium-Based Films. Formation of a Duplex Coating with Polypyrrole
(Springer, 2021-03-03)
In order to improve the corrosion resistance of die-cast AZ91D magnesium alloy in simulated physiological solution, two cerium-based coatings were synthesized. The coatings were electrodeposited from solutions containing ...
