“…Comparing the mechanical and corrosion properties with those of other researchers who studied the friction extrusion of magnesium and its alloys [15–17,44] revealed that the use of bioactive glass particles and the application of the friction extrusion process on the AZ91 rod improved corrosion resistance by at least 74% compared to the initial AZ91 alloy. It is possible, moreover, to achieve mechanical properties similar to or even greater than those obtained in other research by using bioactive glass particles.…”

“…Although the effect of FE process variables on the microstructure and properties of magnesium and its alloys has been studied by various researchers [15][16][17], there have been relatively few studies in the field of metal matrix composite manufacturing, particularly magnesium [18][19][20][21]. Therefore, it is necessary to conduct further research to assess the potential of this process to make gradient composites.…”

The effect of the pre-friction extrusion microstructure of AZ91 billet on the microstructure, mechanical properties, and corrosion resistance of AZ91-bioactive glass surface composite rods was investigated. The results show that friction extrusion on AZ91 alloy billet with cast microstructure results in agglomerated bioactive glass particles in the composite rod microstructure. Compared to as-cast AZ91 alloy, friction extrusion on AZ91 alloy billet with cast microstructure results in 93% more corrosion resistance. Also, friction extrusion on AZ91 alloy billet with extruded microstructure leads to a gradient AZ91-bioactive glass composite rod with ultimate tensile strength, yield strength, and corrosion resistance of 9, 2, and 74% higher than AZ91 alloy rods, respectively.

“…The limitation of low corrosion resistance significantly restricts the application of Mg alloys. Moreover, many factors have an impact on the corrosion resistance of Mg alloys, including precipitate particles, grain boundaries, dislocation density, and residual stresses . Although previous studies consistently reported that the decrease in grain size is beneficial to the corrosion resistance of Mg alloys, residual stress and dislocation density are detrimental to the corrosion resistance .…”

Multipass friction stir processing (FSP) is an effective method to produce a homogeneous microstructure and enhance the mechanical properties of magnesium (Mg) alloys. However, few studies have concentrated on the variation of corrosion resistance of Mg alloys during multipass FSP. Electrochemical alternating current (AC) impedance, polarization behavior, hydrogen evolution, and corrosion morphology were used to investigate the effects of subsequent passes on the corrosion resistance of FSP AZ31 plates. A quasi‐in‐situ observation of the growth of corrosion products was carried out to further study the corrosion behaviors of FSP AZ31 alloy. It is found that subsequent passes could further reduce the grain size of FSP AZ31 alloy and result in an increase in the hardness compared with the first pass. Moreover, subsequent passes are beneficial to the improvement in the corrosion resistance of AZ31 alloy. Pitting corrosion occurs in FSP AZ31 plates, which has not changed after subsequent passes.

“…And the FSW specimen presents a middle value ( ∼ 0.234). Based on previous studies [40,41], samples exhibiting a high coefficient of friction would have a low wear resistance. The results confirm that the surface wear resistance of ZK60 alloy is enhanced by FSW.…”

Owing to the low corrosion and wear resistance of magnesium alloy, surface properties are the key factors affecting its application. But few studies have concentrated on the surface properties of friction stir welded Mg-Zn-Zr alloy. The aim of the present paper is to investigate the effects of friction stir welding (FSW) and subsequent ageing on the surface corrosion and wear resistance of ZK60 alloy. It is found that due to the significant grain refinement and redistribution of precipitates, the surface corrosion and wear resistance of ZK60 plates are enhanced by FSW. Morphology of inter-granular corrosion in base metal is changed into pitting corrosion after welding. Subsequent ageing can significantly reduce the corrosion resistance of the welded plates.
