Abstract:The J 55 steel surfaces have been modified by laser illuminance at twelve different sets of technical parameters. The hardness values at different depths of quench hardened layers on various specimens are measured and their microstructures are investigated. Moreover, the optimum technical parameters in connection with the mechanism of modification are analyzed.
Keywords:steel  laser  surface modification
