At present, there are few studies on microbial corrosion of magnesium anode materials that provide protection for oil pipelines in tidal flat environment. In view an abnormal failure anodes a mud environment, the influence change water content beach AZ31B by sulfate-reducing prokaryote (SRP) was investigated electrochemical methods, weight loss and surface analysis techniques. SRP can grow well...

Surface modification on Mg alloys is highly promising for their application in the field of bone repair. In this study, a new metal-organic framework/MgF₂ (Mg-MOF-74/MgF₂) composite coating was prepared on the surface of AZ31B Mg alloy via pre-treatment of hydrofluoric acid and in situ hydrothermal synthesis methods. The surface topography of the composite coating is compact and homogeneous, an...

Friction stir processing (FSP) has been developed on the principles of friction stir welding (FSW) as an effective and efficien new method for grain refinement and microstructural modification, providing intense plastic deformation as well as higher strain rates than other conventional severe plastic deformation methods. FSP produces an equiaxed homogeneous microstructure consisting of fine gra...

Abstract The effect of grain orientation distribution on the dynamic strength highly textured magnesium alloy AZ31B has been studied in a series plate-impact experiments. Specimens with thicknesses between 0.45 mm and 2 were cut parallel perpendicular to material extrusion direction shock loaded impact stresses 1.4 GPa 3.4 GPa. is found be dependent loading direction, along exhibiting significa...

In the present work, a study was carried out to compare morphology and electrochemical properties of pure graphene-modified hybrid silica sol–gel coatings deposited on anodized AZ31B magnesium alloys. The precursor solution prepared using tetraethoxysilane (TEOS) 3-glycidoxypropyl-trimethoxysilane (GPTMS), with addition chemically modified graphene nanosheets (GN-chem). Homogeneous adherent wer...

In this investigation, an attempt is made to study the tensile and microstructural impact of different gas tungsten arc (GTA) welding processes pulsed current, constant magnetic oscillation welded AZ31B magnesium metal joints. These techniques were chosen because they have potential produce welds with high strength excellent integrity. Five joints produced using each approach, one employing a u...

With a view to improving the surface quality of magnesium (Mg) alloy at warm temperature, ultrasonic-assisted single-point incremental forming (SPIF) is proposed. The Mg during SPIF primarily affected by two parts: orange peel patterns non-contact and scratches adhesive wear contact surface. In this work, AZ31B sheet parts different temperatures ultrasonic amplitudes evaluated examining roughne...
