The effect of surface modification NiTi shape memory alloy on its corrosion behavior in Hanks' solution was determined. near-equi-atomic super elastic (Ni 55.8 wt %) used for this study provided by Memry USA. surfaces heat-treated samples were modified mechanical polishing (MP), electropolishing (EP), and followed chemical passivation (CP). As-heat-treated with straw-colored oxide finishes (SCO) blue-colored (BO) also included the study. Surface analysis performed using auger electron...
Ultrathin AZ31B magnesium alloy chips were recycled by solid state recycling process at different extrusion ratios. The morphology and distribution of the oxide in characterised, interface structure between matrix was investigated means high resolution transmission electron microscopy. results indicate that film introduced from surface chip broken up extrusion. MgO shows a nanoscale spherical particle homogeneously distributes some tiny areas matrix. In ratio range, diameter differs little....
Microarc oxidation (MAO) coating was prepared on the surface of AZ91D magnesium alloy in Na2SiO4-NaOH-C3H8O3 based electrolyte. The morphology and composition with different electrolyte constituent were analyzed by SEM XRD. result showed that MAO composed loose layer dense layer. mainly comprised MgO, Mg2SiO4 MgAl2O4. When Na2SiO3 concentration 20g/L, pores very uniform smooth homogeneous pore. addition NaF to had maximum thickness 17~25μm.
The microarc oxidation (MAO) technique was used to prepare the ceramic coating on surface of as-cast AZ91D magnesium alloy. corrosion resistance alloy and MAO tested by immersion method. microstructure characterized an inverted metallographic microscope. morphology composition were SEM XRD. results showed that prepared coatings at 350V exhibited porous morphology. After immersed in 3.5% NaCl solution for 48h, better than substrate obviously.
