Corrosion and wear-corrosion behavior of NiTi modified by plasma source ion implantation.
The understanding of corrosion behavior in NiTi is critical for the devices using this shape-memory alloy. In order to improve the surface properties of NiTi such as corrosion resistance, plasma source ion implantation (PSII) technique was employed with oxygen as incident ions at three levels of implantation dose (5x10(16), 1x10(17) and 3x10(17) ions/cm(-2)). Pitting corrosion and wear-corrosio...
متن کاملIn vitro corrosion of pure magnesium and AZ91 alloy—the influence of thin electrolyte layer thickness
In vivo degradation predication faces a huge challenge via in vitro corrosion test due to the difficulty for mimicking the complicated microenvironment with various influencing factors. A thin electrolyte layer (TEL) cell for in vitro corrosion of pure magnesium and AZ91 alloy was presented to stimulate the in vivo corrosion in the micro-environment built by the interface of the implant and its...
متن کاملCorrosion Resistance Enhancement of AZ91 Magnesium Alloy Using Ni-P Interlayer and Electrophoretic Deposited 3YSZ Coating
The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...
متن کاملBlood Compatibility of Titanium-Based Coatings Prepared by Metal Plasma Immersion Ion Implantation and Deposition
In this work the suitability of some Tibased coatings as coating for blood-contacting implants is analyzed. Layers of pure Ti, Ti nitride, Ti oxynitrides (TiN1-xOx with x = 0.25, 0.50, and 0.75) and Ti oxides were deposited from a plasma produced by cathodic arc evaporation under addition of N2 and/or O2. The oxynitrides are crystalline with the fcc structure of TiN up to x = 0.25. For x = 0.5 ...
متن کاملEffect of Ti on the Mechanical Properties and Corrosion of Cast AZ91 Magnesium Alloy
Ti addition to AZ91 alloy was been investigated with conventional casting. The microstructure and mechanical property were examined. The Corrosion resistance of all the different Ti addition content alloy was studied in 3.5% NaCl solution through weight loss measurement in constant immersion conditions and potentiodynamic polarization experiments. The results show that addition of Ti with an am...
