Structural Analysis of CoCrMoSi6 Alloy Used in Medical Applications

Abstract:

Increase the life exploitation of implants has been the motor factor in the elaboration of the new biocompatible alloys based on cobalt. The paper aims the complete structural characterizations for CoCrMoSi6 alloy, based on modern investigation methods, like compositional analysis by EDX method, optical and electronic microscopy analysis, X-ray diffractrometric analysis, fracture analysis. The experiments aimed to establish all the structural aspects for CoCrMoSi6 alloy and his recommendation for using to manufacture the components for medical applications. The results obtained from the SEM microstructural analysis, for the original version allied with silicon in percentage of 6%, certify a dendritic structure specific to the cobalt base alloys. This paper established the structural aspects for a new variant of CoCrMoSi6 alloy and recommends their use successfully in the production of components for medical applications.
