Formation of Ca/P ceramic coatings by Plasma Electrolytic Oxidation (PEO) on Ti6Al4V ELI alloy

Autor: S Blanco, D I Naranjo, Y Rodriguez-Jaimes, S J García-Vergara

Publikováno v: Journal of Physics: Conference Series. 935:012031

The formation of PEO ceramic coatings on Ti6Al4V ELI alloy was investigated using a phosphate/calcium containing electrolyte at 300 and 400V at 310K for different times. The Plasma Electrolytic Oxidation (PEO) coated specimens were then heat treated

Scanning electron microscopy of heat treated TiO2 nanotubes arrays obtained by anodic oxidation

Autor: S J García-Vergara, S Blanco, D I Naranjo

Publikováno v: Journal of Physics: Conference Series. 935:012025

Scanning electron microscopy was used to investigate the anatase-rutile transformation of self-organized TiO2 nanotubes obtained on titanium foil by anodizing and subsequent heat treatment. The anodizing was carried out at 20V in an 1% v/v HF acid an

Enriched alloy layer on an Al-Cu alloy studied by cyclic voltammetry

Autor: C. E. Blanco Pinzon, S. J. García Vergara, Peter Skeldon

Publikováno v: Journal of Physics: Conference Series. 786:012031

The behaviour of enriched Al-0.7at.%Cu alloy is investigated using cyclic voltammetry. Enriched alloy layers at the interface between the alloy/oxide film were developed by alkaline etching at 5mAcm-2 in 0.1M sodium hydroxide solution at 298K, with t

Formation of fouling deposits on a carbon steel surface from Colombian heavy crude oil under preheating conditions

Autor: S. J. García Vergara, M Orozco Parra, C. E. Blanco Pinzon, D A Muñoz Pinto, D Laverde, S M Cuervo Camargo

Publikováno v: Journal of Physics: Conference Series. 687:012016

Fouling in heat exchangers is produced by the deposition of undesired materials on metal surfaces. As fouling progresses, pressure drop and heat transfer resistance is observed and therefore the overall thermal efficiency of the equipment diminishes.

Publikováno v: Journal of Physics: Conference Series. 687:012037

The growth of PEO ceramic coatings on AA 2024-T3 aluminium alloy in an aqueous Na2SiO3 (10.5g/l), KOH (2.8g/l) solution at 310 and 400V for 500 and 710s, was investigated. The morphology, roughness and thickness of the coatings were determined by SEM
