Significant Improvement in Mechanical Properties of Biomedical Co-Cr-Mo Alloys with Combination of N Addition and Cr-Enrichment
An improvement in the mechanical properties of a biomedical Ni-free Co-Cr-Mo alloy under as-cast condition has been examined by means of tensile tests and microstructure observations. The solubility of N in Co-Cr-Mo alloys increases with increasing Cr content from 29 to 34mass%. This results in a significant improvement in mechanical properties such as yield stress, tensile strength, and fractu...
متن کاملAN INVESTIGATION TO BAINITE FORMATION MORPHOLOGIES IN NI-CR BEARING LOW CARBON STEELS THROUGH THERMOMECHANICAL PROCESSING
The presence of bainite in the microstructure of steels to obtain a proper combination of strength and toughness has always been desired. The previous works however have shown that the presence of preferred bainite morphologies in the microstructure of any steel would not be readily accessible. In addition, the appearance of different bainite morphologies in the microstructure of any steel is d...
متن کاملEffects of thermal treatments on protein adsorption of Co-Cr-Mo ASTM-F75 alloys.
Post-manufacturing thermal treatments are commonly employed in the production of hip replacements to reduce shrinkage voids which can occur in cast components. Several studies have investigated the consequences of these treatments upon the alloy microstructure and tribological properties but none have determined if there are any biological ramifications. In this study the adsorption of proteins...
متن کاملCORROSION RESISTANCE OF Co-Cr-Mo ALLOY USED IN DENTISTRY ODPORNOŚĆ KOROZYJNA STOPU Co-Cr-Mo WYKORZYSTYWANEGO W STOMATOLOGII
The presented paper studies the effect of the casting technology on the corrosion resistance of Co-Cr-Mo alloy. The investigations were conducted on a commercial alloy with the brand name ARGELOY N.P SPECIAL (Co-Cr-Mo) produced by Argen as well as the same alloy melted and cast by the lost wax casting method performed by a dental technician. The corrosion behavior of the dental alloys in an art...
متن کاملRapid Manufacturing of Co-Cr-Mo Implants by Three-Dimentional Printing Process for Orthopedic Applications
The fabrication of complex-shaped parts out of (wt %) Co-28Cr-6Mo alloy by three-dimensional printing (3DP) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. To produce sound specimens, 3DP processing parameters were tuned. The sintering behavior of the powders was characterized by the dilatometric analysis. Batch sintering in argon atmosphere at 1280 °...
