Purpose: The purpose of this paper is to assess the strategic perspectives of laser treatment of casting magnesium alloys such as MCMgAl12Zn1 MCMgAl9Zn1, MCMgAl6Zn1, MCMgAl3Zn1 using carbide TiC, WC, VC, SiC and Al2O3 oxide powders. The type of powder was taken as a criterion for the technology groups distinguishing in that way five groups of technologies for further research studies. Design/methodology/approach:...
Purpose: The goal of this paper is to present the structure and properties of the cast magnesium alloy after laser treatment. Design/methodology/approach: The laser treatment of magnesium alloys with TiC, WC powders was carried out using a high power diode laser (HDPL). The resulting microstructure in the modified surface layer was examined using optical microscopy, scanning electron microscopy and...
Purpose: In this paper there is presented the structure of the modeling cast magnesium alloy EN-MCMgAl6Zn1 as cast state, after heat treatment and laser treatment. Design/methodology/approach: The presented results concern X-ray qualitative and quantitative microanalysis as well as qualitative and quantitative X-ray diffraction method, light and scanning microscope. A casting cycle of alloys has been...
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...
