Mechanisms of plasma electrolytic oxidation of aluminum at the multi-hour timescales

Corrosion behavior of aluminum oxide coatings created by electrolytic plasma method under different potential regimes

“…In order to create a linear system, the application of alternating voltage of 10 mV was used to disturb the steady state of the system [6]. In this project, Princeton Applied Research Model 1025 made by EG&G Company was used.…”

“…Plasma electrolytic oxidation (PEO) using high voltage is a recently developed surface engineering method [6]. PEO is considered as a method between a common low voltage anodizing in aqueous solutions and a high-energy plasma coating in dry conditions in a controlled gas pressure chamber [7].…”

Analysis of technological approaches to electrochemical surface treatment of aluminum alloys

“…For PEO implementation, it is important to select the type and composition of the working electrolyte [48]. Given the heterogeneity of the studied aluminum alloys due to the presence of intermetallic compounds and hardening phases, an alkaline solution of diphosphate was chosen for PEO treatment.…”

Properties of ZnO/ZnAl2O4 composite PEO coatings on zinc alloy Z1

“…The oxide layers developed by PEO method are usually hard and well adherent to the substrates and can provide effective corrosion and wear resistance [ [8][9][10][11][12] ]. Thus, PEO treatments are well known for corrosion and wear protection of magnesium [ 5 , 7 , [15][16][17], aluminium [ [18][19][20][21][22][23] and titanium [ [24][25][26][27][28][29] ] based alloys.…”
