Effects of non‐isothermal aging process on mechanical properties and corrosion resistance of Al–Mg–Si aluminum alloy

Abstract

Effects of non‐isothermal aging treatment on mechanical properties and corrosion resistance of Al–Mg–Si aluminum alloy were investigated by hardness test, tensile test, intergranular corrosion test, and TEM observation. The results suggested that the NIA process (heating from 30 °C to 190 °C at 20 °C/h) is capable of enduing higher mechanical performances and comparable corrosion resistance to Al–Mg–Si alloys, as compared with that of the T73 condition. The different evolution of precipitates in intra‐grain and grain boundary is supposed to explain the various mechanical performances and corrosion resistance.

One-Step Potentiostatic Deposition of Micro-Particles on Al Alloy as Superhydrophobic Surface for Enhanced Corrosion Resistance by Reducing Interfacial Interactions

“…In recent years, various methods of protective coating [8,9], corrosion inhibitor [10,11], aging process [12,13], mechanical alloying [14], laser treatment [15,16], micro-arc oxidation [17], phosphating process [18], and friction stir welding [19,20] have been reported to enhance the corrosion resistance of Al alloys. However, some coating protection processes with heavy metal ions are bad for environment.…”
