Archwire alloys ,Resist corrosion ,Stainless ,Co-Cr ,Titanium alloys ,

Archwire alloys are available in various forms and shapes for multiple tooth movements like intrusion and retraction of teeth during orthodontic treatment. The major process of degradation of metals is corrosion. Along with the release of elements from metals or alloys, corrosion of orthodontic wires can lead to roughening of the surface and weakening of the appliances and can severely affect the ultimate strength of the material, leading to mechanical failure or even fracture of the orthodontic materials. To resist corrosion, Stainless, Co-Cr, and titanium alloys depend on the formation of a passive surface oxide film. However, even though these protective oxide films are present on the metal surface, metal ions can still be released. The aim of this study is to assess the surface corrosion properties of the samples of polymer-drug coated orthodontic archwires
