WebGebauer et al. investigated the adhesion strength of laser pre-treated CFRP. The laser pre-treated CFRP was coated with 80Ni20Cr by atmospheric plasma spraying. An average adhesion strength of at least 20.3 ± 2.7 MPa was achieved between the coating and the substrate in pull-off testing. WebAug 3, 2024 · Corrosionpedia Explains Coating Strength Coating strength is the measure of adhesion of paint or coating to a surface or substrate. A coated surface is viewed as a three-component system consisting of: Paint Substrate Paint/substrate interface Coating is useless unless it has good adhesion.
4 Types of Tests that Measure the Strength of a Coating
WebMay 24, 2024 · This study aims at investigating the effect of post-deposition solution treatment and ageing (STA) on improving the interfacial adhesion strength in cold spray … The ability of a coating to adhere to a base material is extremely important because without an adequate adhesive bond, the coating could prematurely flake off entirely, leaving the base material exposed to the environment. A frequently used test to determine the adhesive strength of a coating is the pull-off … See more Hardness is a mechanical property that helps a coating resist indentation. (A wider discussion of hardness can be found in the article 5 Ways to Measure the Hardness of a Material.) A harder … See more Abrasion of a coating occurs when all or a portion of the coating is scraped off by another material, which is clearly undesirable because … See more When coatings are applied to base materials that will undergo deformationthen it is imperative that the coating be able to … See more fis a m12
