Corrosion and Residual Strength Analysis of High Pressure Die Casting AM Series Mg Alloys

Abstract

Higher pressure die casting (HPDC) AM series (Mg-Al-Mn) Mg alloys have wide application potential in the automobile industry. To promote its application, systematic investigation on the corrosion performance and corrosion residual strength of HPDC AM50+1Ce and AM60 was carried out. The corrosion of HPDC AM50+1Ce was more uniform, while the pitting corrosion of AM60 was more severe, and the mechanical properties of HPDC AM60 was more sensitive to corrosion. The residual strength of AM50+1Ce and AM60 after corrosion of 648 h was 199 MPa and 183 MPa, respectively. The findings can contribute to a better understanding of the corrosion and residual strength of HPDC AM series Mg alloys.

Impact of Cladding Technology on Residual Stresses within the Renovation of High Pressure Die Casting Molds

“…High melt flow rates of aluminum alloys (up to 120 m/s −1 ), high pressures (up to 120 MPa), and high maximum surface temperatures of mold parts (up to 550 • C) lead to erosion, abrasion, corrosion, and thermal fatigue of the mold. This issue is addressed in publications [1][2][3][4][5].…”
