A systematic study was carried out to evaluate the correlation between high pressure die casting (HPDC) parameters and the mechanial properties of Magnesium alloys. The tested alloys included two conventional alloys: AZ91D and AM50A and a newly developed alloy, RI153M. The nature of the above correlations was semi-empiric, based on computer simulation of the die casting process using MAGMA® sim...

The present study employed a tungsten pH microelectrode to the formation of trivalent chromium conversion (TCC) coatings on Al, AA 2024-T3 aluminum alloy and AZ91D magnesium in SurTec ChromitAL solutions. had sensitivity –60 mV/pH peak final values for pre-treated 2024 were 4.9 3.5, 4.3 4.1, 4.7 respectively. initial value is great importance influencing coating deposition-driven force thicknes...

Magnesium alloys are perspective materials for use in transportation, aerospace and medical industries, mainly because of their good load-to-weight ratio, biocompatibility biodegradability. For the effective production magnesium components by laser powder bed fusion (LPBF) process, process parameters with verified mechanical properties need to be determined. In this paper, we prepared bulk samp...

Magnesium alloys, known as a “21st-century green engineering material”, are widely used in many fields, including during the production and consumption of magnesium alloys die-casting products such AZ91D, AM50, AM60B. In addition, large amount waste is generated, which not only pollutes environment but also wastes secondary resources. Hereby, we reported vacuum gasification—directional condensa...

Trivalent chromium conversion (TCC) coating formation on AZ91D magnesium alloy has been investigated using scanning electron microscopy, energy X-ray dispersive spectroscopy (EDS), photoelectron spectroscoy (XPS). The was formed in a commercial SurTec 650 bath. XPS showed that coatings contained mainly Cr, Zr, O, S and F species, which were assigned to hydrated Cr(III) (Cr(OH)3/CrOOH), ZrO2, Cr...
