Cobalt alloys used in medical applications<br />
Mirabela Minciuna, Petrica Vizureanu<br />
Gheorghe Asachi Technical University of <strong>Iasi</strong><br />
The research is focused on metallic biomaterials which are currently<br />
considered the most widely used class of materials to achieve<br />
prostheses, implants and medical instruments. These types of materials<br />
have very good mechanical pr<strong>op</strong>erties, a good corrosion resistance and<br />
an acceptable biocompatibility. The main point of the paper is<br />
biomaterials metallic, especially Co-Cr group.<br />

Microstructure and phases of c<strong>op</strong>per based SMA<br />

Shape memory alloys (SMAs) based on c<strong>op</strong>per present beside shape<br />
memory effect and superelasticity a high damping capacity especially<br />
on M↔A range. This reversible thermo-mechanical behavior is very<br />
different from the conventional elastic/plastic materials. These unique<br />
pr<strong>op</strong>erties are based on martensitic transformation induced by stress or<br />
temperature variations. Even the martensitic transformation is a<br />
diffusionless transition it can be extremely fast especially on Ni-Ti<br />
shape memory alloys. This work deals with the application of several<br />
SEM, AFM and XRD methods to analyze the mechanisms of thermal<br />
induced martensite transformation in CuZnAl alloy polycrystals. The<br />
martensite dimensional characteristics were determined in 2D and 3D<br />
modes. The martensite structure was morphologically characterized<br />
after two heat treatment conditions. By chemical means the phases<br />
obtained after the transformation were followed to establish the<br />
recovery heat treatment influence on water cooled quenched sample.<br />
