In vitro Wear Rate and Co Ion Release of Compositionally and Structurally Graded CoCrMo-Ti6Al4V Structures.
Novel, unitized structures with porous Ti6Al4V alloy on one side and compositionally graded, hard CoCrMo alloy surface on the other side have been fabricated using laser engineered net shaping (LENS™) process. Gradient structures with 50%, 70% and 86% CoCrMo alloy on the top surface showed high hardness in the range of 615 and 957 HV. The gradient structures were evaluated for their in vitro we...
متن کاملCorrosion Behavior of Solution- Annealed CoCrMo Medical Implant Alloys
Corrosion behavior of solution annealed high-carbon and low-carbon CoCrMo wrought alloy, commonly used in medical joint implants, was investigated. The surface passivation properties remained similar with and without the various solution anneal conditions, while the rate of corrosion was lower for solution annealed high-carbon CoCrMo. Corrosion was found to target phase boundaries and certain g...
متن کاملThe Galvanic Interaction Between a CoCrMo Alloy, Pure Titanium and Two Different Dental Amalgams with Special Attention on the Area Size
The purpose of this study was to determine the galvanic interaction between pure titanium, a CoCrMo alloy, as well as their galvanic interaction with a high copper and a conventional amalgam at different area ratios. Pure titanium, a CoCrMo alloy and two dental amalgams with different copper compositions were tested in this study in 0.9% NaCl environment of pH 7. Polarization curves were record...
متن کاملFracture Mechanism of CoCrMo Porous Nano-composite Prepared by Powder Metallurgy Route
The main aim of this research was to find the mechanism for the failure of the CoCrMo porous nano-composite by characterizing microstructural changes and fractured surface after compression test. For this purpose, porous nano-composites were prepared with the addition of bioactive glass nano-powder to Co-base alloy with 22.5% porosity by the combination of space-holder and powder metallurgy tec...
متن کاملAlbumin adsorption on CoCrMo alloy surfaces
Proteins can adsorb on the surface of artificial joints immediately after being implanted. Although research studying protein adsorption on medical material surfaces has been carried out, the mechanism of the proteins' adsorption which affects the corrosion behaviour of such materials still lacks in situ observation at the micro level. The adsorption of bovine serum albumin (BSA) on CoCrMo allo...
