Evaluates laser-induced damage resistance in 7075 aluminum alloy, suggesting significant improvements with coating.
To improve the laser-induced damage resistance of 7075 aluminum alloy, a typical aerospace material, a laser-resistant coating material for the surface of 7075 aluminum alloy was prepared in this paper. The performance of 7075 aluminum alloy coated with this coating was analyzed and tested by combining numerical simulation and experimental verification. The test results show that under the same laser irradiation conditions and geometric dimensions, the breakdown time of 7075 aluminum alloy coated with the laser-resistant coating is prolonged by 541.6%, and its laser-induced damage resistance is significantly improved.
