Computational Simulation and Prototype Testing of Nanocoating on Products in Aerospace Industry

Abstract

The material damages in aerospace industry caused by correction can be detected in many different products including welded and bolted areas in aircraft and jet engines. The corrosion occurs when different conducted materials contact to each other in electrolyte media and different conducted materials present potential difference that causes rusting. The rusting problems in products lead both safety issues and billions of dollar loss in different businesses including aerospace industry. This paper studies the rusting mechanism and anti-corrosive coatings by applying computational simulation and prototype experiment. Both computer-aided analysis and sample testing demonstrated similar results which confirm the feasibility of analytic methodology introduced in this research paper.

Computer Aided Analysis and Prototype Testing of Nanocoated Mechanical Components

“…The potential difference caused by corrosion drives galvanic current inside the metallic materials [1]. To decrease corrosion speed, some conventional methods were applied to control surface contact geometry, stabilizing bridge contacting conditions, providing appropriate material composition, and reducing potential when connecting different materials [2,3]. In addition, the material geometry ratio must be manipulated and to dissolute the current density to reduce the rusting speed [4,5].…”

To effectively handle corroding problems, the nanocoating technology has been studied and developed to improve material anti-corrosion performance because of its superior rustresistant property [6,7].…”
