Chromium Deposition on Cobalt-Based Alloys by Pack-Cementation and Behaviour of the Coated Alloys in High Temperature Oxidation
Two TaC-strengthened cobalt-based alloys, with compositions Co-10Cr-0.25C-4.4Ta and Co-10Cr-0.5C-8.7Ta (wt.%) underwent Cr-deposition by pack-cementation, followed by heat-treatment to allow Cr diffusing deeper in their sub-surface. Thereafter they were tested for 50 hours at 1200°C in a thermobalance. These alloys were successfully enriched in chromium, with a maximal content on surface of abo...
متن کاملA novel route for processing cobalt-chromium-molybdenum orthopaedic alloys.
Spark plasma sintering has been used for the first time to prepare the ASTM F75 cobalt-chromium-molybdenum (Co-Cr-Mo) orthopaedic alloy composition using nanopowders. In the preliminary work presented in this report, the effect of processing variables on the structural features of the alloy (phases present, grain size and microstructure) has been investigated. Specimens of greater than 99.5 per...
متن کاملCobalt-chromium alloys in fixed prosthodontics in Sweden
Aim: The aim of this study was to compile the usage of Co-Cr alloys in fixed prosthodontics (FP) among dental laboratories in Sweden. Methods: From March to October 2015, questionnaires were sent to 542 registered dental laboratories in Sweden. The questionnaires were divided in two parts, one for fixed dental-supported prosthodontics (FDP) and one for fixed implant-supported prosthodontics (FI...
متن کامل[Mechanical properties of metal-ceramic systems from nickel-chromium and cobalt-chromium alloys].
BACKGROUND/AIM Metal-ceramic bond strength and alloys' elastic modulus clearly determine the potential of alloy application, because the ceramic integrity during mastication depends on these two characteristics. The aim of this study was to evaluate metal-ceramic bond strenght and elastic modulus of cobalt-chromium alloys in making porcelain-fused-to-metal restorations, regarding the applicatio...
متن کاملEffect of surface passivation on corrosion of a cobalt-chromium dental alloy: surface morphology and chemical composition studies
Abstract Background and Aim: Biocompatibility in some respects depends on the corrosion behavior of dental alloys. The purpose of this study was to investigate the effect of surface passivation of a cobalt chromium alloy on corrosion behavior. Materials and methods: In this experimental study, 20 samples of Flexicast dental alloy were prepared according to ADA97 standard and after casting, t...
