Study of Nanoparticle Coating Technology to Control Product Corrosion in Aerospace Industry

:The product corrosion causes safety issues in flight vehicles and capital losses in aerospace industry. Since some geometrical surfaces and shapes such as hidden slot and pocket structure can easily contain moisture droplets and air impurity, the corrosion caused by chemical composite in aerospace products can be accelerated leading sudden flight vehicle failure and even personal fatal injury. Nanoparticle coating technology is a relatively new and efficient methodology in anti-corrosion since it can distribute very small material particles in complex geometrical structures to produce extremely durable and very strong surface coating to significantly decrease product corrosion. This paper studies the anti-corrosion mechanism in order to reduce corrosion damage by applying computer-aided simulation and prototype testing to verify nanoparticle coating performance. Both computer-aided simulation and prototype testing show close results which validate the methodology introduced in this research and demonstrate superior corrosion-resistant performance of nanoparticle coating to current regular coating methodologies.
