material properties of cobalt chromium

Cobalt-chrome - WikipediaCo-Cr alloys show high resistance to corrosion due to the spontaneous formation of a protective passive film composed of mostly Cr2O3, and minor amounts of cobalt and other metal oxides on the surface. As its wide application in biomedical industry indicates, Co-Cr alloys are well known for their biocompatibility. Biocompatibility also depends on the film and how this oxidized surface interacts with physiological environment. Good mechanical properties that ...【Get Price】

Early Fixation of Cobalt-Chromium Based Alloy Surgical Implants to ...9 May 2012 ... Therefore, implants ability to provide early, stable, and osseous fixation is required to ensure success in clinical cases. Incomplete anchorage between the implants surface and bone might lead to aseptic loosening and subsequent failure in the prostheses [1]. cobalt chromium (CoCr) based alloys have been widely used for prosthetic arthroplasty. Their mechanical properties seem to be suitable material for the purpose of total hip and knee joint arthroplasty [2,3].【Get Price】

electrochemical and mechanical properties of cobalt-chromium ...In dentistry cobalt-chromium alloys are frequently used for partial denture frameworks. For fabrication of some complex frameworks, separate metal segments have to be joined. The longevity of these restorations is limited due to the mechanical or corrosive failure of the joints. The purpose of this study was to determine which joining method offers the best properties to cobalt-chromium alloy frameworks. Intact specimens, brazed and two types of laser-welded joints were compared for ...【Get Price】

Abstract: The microstructures and mechanical properties of cobalt-chromium (Co-Cr) alloys produced by three CAD/CAM-based processing techniques were investigated in comparison with those produced by the traditional casting technique. Four groups of disc- (microstructures) or dumbbell- (mechanical properties) specimens made of Co-Cr alloys were prepared using casting (CS), milling (ML), selective laser melting (SLM), and milling/post-sintering (ML/PS).【Get Price】
