摘要: Purpose: . The aim of this work was to improve the surface layer cast magnesium alloys by laser treatment and determine parameters. Design/methodology/approach: with alloying SiC powder particle size below 75μm carried out using a high power diode (HPDL). resulting microstructure in modified examinated scanning electron microscopy. Phase composition determined X-ray diffraction method XPert device. measurements microhardness also studied. Findings: alloyed region has fine hard carbide particles. Microhardness significantly improved as compared alloy without treatment. Research limitations/implications: investigations were conducted for MCMgAl12Zn1, MCMgAl9Zn1, MCMgAl6Zn1, MCMgAl3Zn1 75μm. One used range from 1.2 2.0 kW. Practical implications: results obtained investigation promising other conventional processes. High Power Diode Laser can be an economical substitute Nd:YAG CO2 feeding Originality/value: value is definition influence parameters on quality, layer.
