Laser processing for reliability and corrosion resistance enhancement of equipment working in hostile environments

The possibilities of material surface processing by different types of lasers (continuous-wave, high repetition rate CO 2 ) with the aim of corrosion resistance growth are discussed. The researches of structural peculiarities and mechanisms of corrosion behavior improvement of metal materials in hostile environments after laser welding, melting and alloying, and the examples of industrial applications are presented.
