Tribo-electrochemical characterization of metallic biomaterials for total joint replacement.
Knee and hip joint replacement implants involve a sliding contact between the femoral component and the tibial or acetabular component immersed in body fluids, thus making the metallic parts susceptible to tribocorrosion. Micro-motions occur at points of fixation leading to debris and ion release by fretting corrosion. β-Titanium alloys are potential biomaterials for joint prostheses due to the...
متن کاملElectrochemical Preparation and Characterization of Mn5O8 Nanostructures
Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...
متن کاملelectrochemical evaluation of hydroxyapatite/zrn coated magnesium biodegradable alloy in ringer solution as a simulated body fluid
magnesium alloys as biodegradable materials can be used in body as an implant materials but since they have poor corrosion resistance, it is required to decrease their corrosion rate by biocompatible coatings. in this study, hydroxyapatite (ha) coatings in the presence of an intermediate layer of zrn as a biocompatible material, deposited on az91 magnesium alloy by ion beam sputtering method at...
متن کاملElectrochemical and Tribological Behaviour of Oxide Dispersion Strengthened Duplex Stainless Steel in Mine Water Environment
Abstract This work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (DSS). DSS sintered composites of different volume percent (% vol) of partially stabilized zirconia (PSZ) was developed using powder metallurgy (PM) technique. Electrochemical behaviour was studied at room temperature, using open circuit potential and potentiody...
متن کاملElectrochemical Corrosion Behavior of Ta2N Nanoceramic Coating in Simulated Body Fluid
In order to improve the corrosion and wear resistance of biomedical Ti-6Al-4V implants, a Ta₂N nanoceramic coating was synthesized on a Ti-6Al-4V substrate by the double glow discharge plasma process. The Ta₂N coating, composed of fine nanocrystals, with an average grain size of 12.8 nm, improved the surface hardness of Ti-6Al-4V and showed good contact damage tolerance and good adhesion streng...
