The effects of cerium implantation on the oxidation behavior of AZ31 magnesium alloys

Oxidation of magnesium alloys at elevated temperatures in air: A review

“…AZ31 was surface alloyed with Ce by Wang et al [142] through ion implantation. There was a lower oxidation weight gain of the implanted AZ31…”

Effect of gadolinium on microstructure and rolling capability of AZ31 alloy

“…Magnesium alloys gain a growing popularity in transportation industry due to their high potential for lightweight applications [1]. However, magnesium automotive applications are currently limited to casting (such as covers, housing and brackets), but its usage can be increased if wrought Mg alloy products are more readily available.…”

The characterization of surface films formed on molten magnesium and AZ91D alloy in air/1,1,1,2-tetrafluoroethane atmospheres

“…It is therefore necessary to take appropriate measures to prevent the melt from oxidizing and burning. Many methods have been investigated and applied to reduce or inhibit the oxidizing and burning of molten magnesium and its alloys in air, such as flux covering protection, gas protection without flux [3,4] and ignition-proof by alloying [5,6]. Among these methods, sulfur hexafluoride (SF 6 ) is currently considered as an effective protective gas and extensively used to prevent magnesium and its alloys from oxidizing and burning during melting and casting processes.…”

“…Among these methods, sulfur hexafluoride (SF 6 ) is currently considered as an effective protective gas and extensively used to prevent magnesium and its alloys from oxidizing and burning during melting and casting processes. Because SF 6 can form a thin, coherent and stable film on its surface which can effectively reduce or inhibit the melt further contacting with oxygen in the atmosphere [3,4]. But in the process of SF 6 gas being used, there is a lot of SF 6 gas leftover and decomposition products being released in environment, which will result in serious greenhouse effect and environment pollution [7,8].…”

“…But in the process of SF 6 gas being used, there is a lot of SF 6 gas leftover and decomposition products being released in environment, which will result in serious greenhouse effect and environment pollution [7,8]. With increasing environmental concerns in recent years, the use of SF 6 gas in industries is strict restricted or forbidden in many countries of the world. It is an urgent subject to develop or look for alternative gases which are low environmental impact and low toxicity to replace or reduce the use of SF 6 for the melt protection in the melting and casting of magnesium and its alloys.…”
