Abstract Scope |
The utilization of a high-deposition rate cold spraying (HDR-CS) has revolutionized the approach to component repair and protection. However, these coatings suffer from micro-defects due to inadequate particle bonding, thus resulting in premature failure. Especially when subjected to mechanical and chemical environments, their synergism can greatly diminish the lifespans of HDR-CS coatings. To mitigate these defects, we propose the application of post-laser processing to both densify and strengthen their tribo-corrosion performance in chloride-based environments. By correlating the change of microstructural, mechanical, and wettability properties of the HDR-CS coatings to their tribo-corrosion performance, it was found that post-laser processing is a useful method to enhance its surface properties. The critical change in tribo-corrosion mechanisms is further discussed in this work. |
