“…The sample was the working electrode, and the stainless steel container was the counter electrode. The electrolyte was 8 g/L KF·2H 2 O, 4 g/L (NaPO 3 ) 6 and 0.8 g/L Ca(OH) 2 and was kept at 20-25 °C by a water cooling system. After the MAO treatment, each sample was rinsed thoroughly using flowing deionized water and dried using flowing air.…”

“…The corrosion rate for asextruded Mg-1.5Sr substrate after immersion of three days was relatively high. Then the decline of the corrosion rate was owing to the precipitation of corrosion products such as Mg(OH) 2 corrosion of Cl − to some extent [36,37]. In addition, during the subsequent immersion time, the successive decrease in the corrosion rate should be attributed to the formation and dissolution of the corrosion product layer [38,39].…”

“…Magnesium (Mg) alloys are a novel kind of biomedical material. They have potential application as biodegradable and bioresorbable bone graft substitutes due to their degradability and biocompatibility and because their mechanical properties are similar to those of bone [1][2][3][4][5][6][7][8]. Strontium (Sr) is a necessary trace element in the human body.…”

As-extruded Mg-Sr alloy, a kind of promising biodegradable biomedical material, was coated using micro-arc oxidation and also using a phosphate conversion coating. The corrosion behaviors were investigated using Hanks' solution. The corrosion of the as-extruded Mg-Sr alloy became more serious with increasing immersion time; that is, the corrosion pits became more numerous, larger and deeper. The micro-arc oxidation coating and the phosphate conversion coating were effective in improving the corrosion resistance of the as-extruded Mg-Sr alloy. The micro-arc oxidation coating was much more effective. Moreover, the as-extruded Mg-Sr alloy and the coated as-extruded Mg-Sr alloy exhibited lower corrosion rates than the as-cast Mg-Sr alloy and the corresponding coated as-cast Mg-Sr alloy, indicating that the corrosion properties of the coated samples are dependent on their substrates. The finer microstructure of the substrate of the as-extruded condition corroded much slower. The corrosion resistance of the coated Mg-Sr alloy depended on the coating itself and on the microstructure of the substrate.

“…In a 3.5% NaCl solution the anodic current density of the aluminum alloy sample with the GPTMS/rGO coating was reduced by several orders of magnitude compared with those of the bare aluminum alloy or the sample with graphene film. Other authors [71] fabricated a polymethyltrimethoxysilane (PMTMS)/hydroxyapatite (HA) hybrid coating on a magnesium alloy by hydrothermal treatment and the immersion method. The results demonstrated that the corrosion resistance of the silane hybrid coating was significantly enhanced compared with the naked magnesium alloy.…”

Due to the fact that it is highly toxic and carcinogenic, chromate-based surface treatment is restricted or gradually reduced in many countries. Among the alternatives to replace conventional chromate coatings, organosilanes show some important advantages such as competitive price and environmental compatibility. These substances inhibit the corrosion processes of metal surfaces but cannot offer long term-protection. For this reason, silane films have been modified by different procedures. In this paper, methods of improving the anticorrosive protective performance of silane films have been presented.

“…Cu-Nb microcomposite wires have drawn wide attention due to their good combination of high mechanical strength and electrical conductivity, thus making them be a good candidate for winding of high-field pulsed magnets [1][2][3][4][5]. Magnetoresistance (MR) is the change in resistivity of the materials induced by the interaction of magnetic field with conductive electrons in materials.…”

The effects of annealing on microstructure, magnetoresistance, and hardness of an in situ Cu-Nb microcomposite wire have been investigated. Neither changes in microstructure nor hardness were found until 500°C. Particularly, microstructural change within the Nb films was observed in the annealed samples. The room-temperature magnetoresistivity was almost negligible, while magnetoresistivity at -196°C increased with magnetic field. At temperature above 500°C, recovery and recrystallization occurred, and both the resistance and hardness decreased.
