Scientists from the Institute of Continuous Media Mechanics of the Ural Branch of the Russian Academy of Sciences and Perm National Research Polytechnic University (PNIPU) have found a way to increase the fatigue life of metal for parts of gas turbine engines and oil and gas pipelines by six times. This was reported by the press service of the university.
Such products are subjected to high loads during operation, which causes microcracks to form on their surface, leading to the destruction of parts. Scientists have proposed a method of metal processing using a laser.
Laser shock hardening can restrain the development of microcracks, significantly extending the life of the part. Scientists from PNIPU and the Institute of Continuous Media Mechanics of the Ural Branch of the Russian Academy of Sciences have determined a processing mode in which the fatigue life of the product is increased sixfold.
During this processing, high-energy pulsed laser radiation changes the microstructure of the surface and forms a hardened layer up to 1 mm. The obtained research results can be useful in creating durable and reliable industrial critical products.
