Abstract
Plasma spraying is of great interest for a wide range of industrial applications, and especially for the fast deposition of ceramic coatings. In this context, three different types of feedstocks are typically used: solid powders, suspensions or solutions. To optimize the prepared products microstructure, a focus is mainly put on spraying parameters, whereas the feedstocks' chemistry and its tuning potential is often neglected. This article is focused on the preparation of ceramic coatings using a novel approach: combustion-assisted solution plasma spraying. This method involves spraying feedstocks designed as solutions for combustion synthesis, combining metal nitrates and a fuel resulting in exothermic reactions to produce the desired materials. Coatings of three different materials were prepared to prove the feasibility of the method for various materials: Al2O3, ZnO and MgO. The influence of the fuel selection and concentration on the coatings' microstructures was studied in detail for Al2O3 deposition.
期刊介绍:
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
