Process Monitoring of Plasma Electrolytic Oxidation
Plasma electrolytic oxidation (PEO) is a potential technique to coat a dense ceramic oxide layer on the surface of light metals, e.g. Al, Mg or Ti. In our PEO process, Al-pieces are emerged in aqueous solutions containing dissolved silicate/alkali, e.g. KOH/NaOH and K 2 SiO 3 /Na 2 SiO 3. Using a DC-pulsed system with 20Hz, micro-arcs are induced at the surface of the pieces randomly and plasma...
متن کاملPlasma Electrolytic Oxidation Coatings on Lightweight Metals
Lightweight metals, e.g. aluminum (Al), magnesium (Mg), titanium (Ti) and their alloys are of great importance for applications in various machinery and transportation system, espe‐ cially in aerospace and automobile products due to their high strength-to-weight ratio and superior physical and chemical performances. However, their poor tribological properties, such as low wear resistance, high ...
متن کاملReview of the Soft Sparking Issues in Plasma Electrolytic Oxidation
A dense inner layer is highly valued among the surface coatings created through plasma electrolytic oxidation (PEO) treatment, because the PEO coating has been troubled by inherent porosity since its conception. To produce the favored structure, a proven technique is to prompt a soft sparking transition, which involves a sudden decrease in light and acoustic emissions, and a drop in anodic volt...
متن کاملAchieving surface chemical and morphologic alterations on tantalum by plasma electrolytic oxidation
BACKGROUND Search for materials that may either replace titanium dental implants or constitute an alternative as a new dental implant material has been widely studied. As well, the search for optimum biocompatible metal surfaces remains crucial. So, the aim of this work is to develop an oxidized surface layer on tantalum using plasma electrolytic oxidation (PEO) similar to those existing on ora...
متن کاملCharacterization of Oxide Film Formed on Ck45 Steel by Plasma Electrolytic Oxidation Method
Plasma electrolytic oxidation (PEO) is the new, environmentally and cost-effective method for coating the metals. This method vastly has been studied for coating Aluminum, Titanium and Magnesium and their alloys and recently for steel. In present study, Ck45 steel samples were coated by PEO method in order to improve corrosion resistance. During this process specimens were immerged in carbonate...
