Plasma 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 کاملProcess 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 کاملOsseointegration improvement by plasma electrolytic oxidation of modified titanium alloys surfaces.
Titanium (Ti) is a material frequently used in orthopedic applications, due to its good mechanical properties and high corrosion resistance. However, formation of a non-adherent fibrous tissue between material and bone drastically could affect the osseointegration process and, therefore, the mechanical stability of the implant. Modifications of topography and configuration of the tissue/materia...
متن کاملComparative Sem and Edx Analysis of Surface Coatings Created on Niobium and Titanium Alloys after Plasma Electrolytic Oxidation (peo)
Original scientific paper In the paper, the SEM and EDS study results of the surface coatings formed on the niobium and titanium alloys (TNZ, NiTi, Ti6Al4V) after the Plasma Electrolytic Oxidation (PEO), also known as Micro Arc Oxidation (MAO), are described. For the experiment of the PEO treatment, a non-conventional electrolyte, based on the concentrated orthophosphoric acid, was used. Copper...
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...
