| description |
Anodizing also known as anodic oxidation coatings have attracted significant interest in
the study because of their potential to improve the corrosion resistance of alloys. Anodic
oxidation coatings are usually chosen for special applications heavy duty corrosion resistance
is required. Previously, chromate compounds were widely used for producing
conversion coatings to protect most metallic surfaces such as aluminum, steel and
magnesium alloys. In spite of its toxicity hexavalent chromate (IV) has remain an
essential ingredient in the metal finishing industry for corrosion control. But combining
the economic impact of corrosion damage, the environmental and health problems
caused by hexavalent chromate (IV), and the increasing the regulatory restrictions,
scientists have a huge incentive to develop a new generation of environmentally friendly
protective coating systems. The objective of this research is to determine the corrosion
resistance of AZ91D magnesium alloy utilizing sodium metavanadate (NaVO3).
Besides, to study on surface microstructure, thickness, surface roughness and chemical
composition related to the coating and its contribution to corrosion performance. Then,
investigate the corrosion behavior and corrosion protection mechanism of AZ91D
magnesium alloy. Sodium metavanadate (NaVO3) is used as anelectrolytesolution to
form coating in this research. |
