Analysis of the Advantages of Laser Processing of Aerospace Materials Using Diffractive Optics

We considered possibilities of an application diffractive free-form optics in laser processing metallic materials aerospace production. Based on the solution inverse problem heat conduction, algorithm was developed that calculates spatial distribution power density irradiation order to create required thermal effect materials. It found use for beam shaping made it possible obtain specified properties processed Laser hardening parts chrome–nickel–molybdenum steel performed. This allowed us increase wear resistance due creation surface layer a structure has increased hardness. In addition, method annealing sheet from aluminum–magnesium alloy and low-alloy titanium alloys developed. Application this opened opportunities expanding forming options these improving precision manufacturing aircraft engine parts. also shown welding by pulsed with redistribution energy makes strength welded joint heat-resistant nickel-based superalloy. Increasing adhesion gas turbine became treatment using optics.
