Unique properties, development perspectives and expected applications of laser treated casting magnesium alloys

The purpose of the article is to present the unique properties of casting magnesium alloys subjected to surface treatment with the high power diode laser, to indicate the development outlooks of the technology and to present its application opportunities in the automotive industry. The laser alloying and cladding of hard titanium and tungsten carbides particles into the substrate surface improves the mechanical and functional properties of the investigated materials to a satisfactory extent. In view of the demand from the automotive sector for components and parts made of lightweight alloys, the development prospects of their effective manufacturing technology meeting the expected product properties, including surface laser treatment, were evaluated to be very high.
