Title

STUDY OF SURFACE NANO-CRYSTALLIZATION ON PROPERTIES OF AZ31B ALLOY COATED BY PLASMA ELECTROLYTIC OXIDATION

Pages

  77-90

Abstract

 In current study effect of SEVERE SHOT PEENING pretreatment on PLASMA ELECTROLYTIC OXIDATION coating of MgAZ31B is investigated. It was revealed that shot peening increases surface energy and discharge sites enhances finally energy of discharges reduces. In short term, absorption of nanoparticles is improved by more than 20% while it reduces to 50% of non-pretreated sample. Changes in surface roughness and porosity volume lead to reduction of wetting angle from 48 to 29 degrees for non-pre-treated and pre-treated sample, respectively. Although shot peening reduces porosity level, application of titania nanoparticles reduces thickness of coating and therefore their simultaneous application reduces corrosion resistance. Most passive corrosion potential, -1.45V, is ascribed to pretreated sample that were coated in nanoparticle-free electrolyte.
