A short note on the various thermal spray coating processes and effect of post-treatment on Ni-based coatings

In the fabrication of equipment and device components that require surface qualities such as corrosion, oxidation and wear resistance, metal surface coating is an efficient and secure method. The main purpose of the coating application could be decorative, functional, or both. Functional coating can be used forimproving surface properties for example wear resistance, oxidation, corrosion, and adhesion. In contrast, cosmetic coatings, such as paints by designers, have been applied to render the product/material more desirable. Nowadays, various coating methods are being implemented to obtain the required practical or cosmetic properties. Some of the most effective and desirable approaches for preserving/protecting fresh machine parts from tear, heat corrosion and oxidation is the thermal spray coating technique. A concise description of the various spraying methods, their basic concepts, disadvantages and implementations is included in this article. In addition to these characteristics, the properties of the coating processes and the various methods used to avoid corrosion are easily identified. Copyright (c) 2021 Elsevier Ltd.
