Purpose: The aim of this work was to improve the properties of the surface layer of the MCMgAl12Zn1 cast magnesium alloy. This improvement can be achieved by modification of surface layer microstructure by melting and simultaneous feeding the silicon carbide particles into the weld pool. Design/methodology/approach: Laser alloying of the MCMgAl12Zn1 magnesium alloy with the silicon carbide was carried...
Purpose: The aim of this work was to improve the surface layer cast magnesium cast alloys by laser surface treatment, determine the laser treatment parameters and examine structure and properties. Design/methodology/approach: The laser treatment of magnesium alloys with alloying SiC and TiC powders with the particles size below 75 μ m and over 6.4 μm was carried out using a high power diode laser...

Purpose: The aim of this work was to investigate structure and mechanical properties of the MCMgAl12Zn1 casting magnesium alloys after laser treatment. The laser treatment was carried out using a high power diode laser (HPDL). Design/methodology/approach: The laser processing of TiC, WC, SiC particles in MCMgAl12Zn1 and the resulted microstructures and properties are discussed in this paper. The resulting...
