Laser heat treatment of nickel-based alloys – a review

Kukliński Mateusz, Szymański Michał, Przestacki Damian

Archives of Mechanical Technology and Materials

2019

Vol. 39

46--53

In this paper researches which focus on laser heat treatment of nickel-based alloys are reviewed. Studies published from 1970s until today are taken into consideration. Publications which focus on influence of laser thermal processing on surface layer condition both on solid materials and predeposited coatings are described. Laser technologies in which additional materials are delivered during the process are not considered. In order to focus on studies investigating microstructural changes resulting mainly from material remelting, laser shock processing is also disregarded.

Geometrical structure of surface after turning of 316L stainless steel in laser assisted conditions

The effects of turning 316L steel in a laser assisted machining are presented in this paper. The properties of 316L stainless steel are also shown in this article. In order to show correlation between the technological parameters, microgeometry of cutting tools and geometrical structure of surface, turning of material in grade 316L supported by laser has been executed. In addition, optical examination of cutting inserts has been performed and geometrical measurements of machined surfaces have been taken. The results of researches on the effects of the technological parameters and cutting tool's microgeometry on the geometrical structure of the 316L steel surface after turning in LAM conditions are described.
