A Review of Coating Methods for Surface Protection

Abstract

For various coating applications, a broad range of coating techniques and materials are available, all of which have the same general goal of shielding a component or structure from mechanical or chemical harm. Reduced manufacturing costs are one advantage of this protective feature since it eliminates the need to fabricate new parts. Hard and rigid metallic alloys, ceramics, bio-glasses, polymers, and tailored plastic materials are among the coating materials that are available, offering designers a wide range of options for long-lasting protection. Many techniques have been developed and studied up to this point, including thermal spraying, sol-gel, micro-arc oxidation, physical/chemical vapor deposition, and electrode position. Despite the benefits that each of these procedures offers, there are always issues that restrict their use. However, by using the advantages of each process in a multi-method coating, there are several ways to address the shortcomings of coating procedures. These coating techniques are contrasted and categorized in this article. Future developments might lead to improved protective properties through the use of increasingly sophisticated coating methods and materials.
