چکیده
The effect of laser surface melting on the corrosion resistance AZ31 Mg alloy in 0.1 M NaCl solution was investigated using different processing conditions (energy densities 14 and 17 J cm?2). Laser treatment induced rough surfaces primarily composed oxidized species Mg. XPS analysis revealed that concentration Al increased significantly as a consequence LSM. Electrochemical impedance spectroscopy showed remarkably polarization passive-like region about 100 mV, determined by potentiodynamic polarization. Analysis results obtained provide solid evidence within immersion times used this study, LSM under open circuit anodic

Laser surface structuring of AZ31 Mg alloy for controlled wettability.
Structured surfaces exhibit functional properties that can enhance the performance of a bioimplant in terms of biocompatibility, adhesion, or corrosion behavior. In order to tailor the surface property, chemical and physical methods can be used in a sequence of many steps. On the other hand, laser surface processing can provide a single step solution to achieve the designated surface function w...

متن کاملPhenolic Modified Ceramic Coating on Biodegradable Mg Alloy: The Improved Corrosion Resistance and Osteoblast-Like Cell Activity
Magnesium alloys have great potential for developing orthopedic implants due to their biodegradability and mechanical properties, but the rapid corrosion rate of the currently-available alloys limits their clinical applications. To increase the corrosion resistance of the substrate, a protective ceramic coating is constructed by a micro-arc oxidation (MAO) process on ZK60 magnesium alloy. The p...
متن کاملImprove sensitization and corrosion resistance of an Al-Mg alloy by optimization of grain boundaries
The sensitization and subsequent intergranular corrosion of Al-5.3 wt.% Mg alloy has been shown to be an important factor in stress corrosion cracking of Al-Mg alloys. Understanding sensitization requires the review of grain boundary character on the precipitation process which can assist in developing and designing alloys with improved corrosion resistance. This study shows that the degree of ...
متن کاملDynamic Recrystallization Behavior and Corrosion Resistance of a Dual-Phase Mg-Li Alloy
The hot deformation and dynamic recrystallization behavior of the dual-phase Mg-9Li-3Al-2Sr-2Y alloy had been investigated using a compression test. The typical dual-phase structure was observed, and average of grain size of as-homogenized alloy is about 110 µm. It mainly contains β-Li, α-Mg, Al₄Sr and Al₂Y phases. The dynamic recrystallization (DRX) kinetic was established based on an Avrami t...
