At the Chelyabinsk State University (ChelSU) and the Perm Federal Research Center of the Ural Branch of the Russian Academy of Sciences (PFRC UB RAS), the durability of aircraft parts has been improved through laser treatment. This was reported by Ksenia Manukhina, a graduate of the Faculty of Physics at ChelSU.
The laser shock peening technology involves firing a laser with ultrashort pulses at a target on the metal. During the process, a dent forms on the surface of the material, thereby increasing the strength of the product.
During the impact, the crystal lattice of the material undergoes deformation, and it tries to return to its original position. Due to these opposing actions, residual stresses are retained in the metal, which prevent further deformation loading from causing serious damage to the metal plate.
