The microstructure and microhardness of the surface layer of annular projections on disks of steel-copper powder pseudoalloy are investigated after laser heat treatment by a 1-kW fiber laser. The maximum micro-hardness of 1000 HV is attained within the martensite formed in pearlite colonies of the initial steel-copper pseudoalloy. The properties of the surface layer depend not only on the laser parameters but also on the surface geometry of the samples. [ABSTRACT FROM AUTHOR] |
