Results are presented on the mechanism of passivation of Co-Cr-Mo biological implant alloys in physiological serum using open circuit potentiometry, potentiodynamic curves, and electrochemical impedance spectroscopy. The potential dependence of impedance data and the analysis of the parameters obtained indicate a progressive diminution of the initial layer thickness and the simultaneous formation of a second higher resistive layer. In more severe conditions than the existent in human body, the metallographic examination of the alloy surface shows localized corrosion in interdendritric regions. Elemental analysis of the surface reveals the presence of higher chromium content in these regions. The presence of chlorine was not detected, which suggested that during preferential attack, soluble species are also formed.

This article aims to show that the challenges of psychology in working with mental health in the field of drugs is traversed by both the conceptions molded by biopolitical forces (FOUCAULT) as the decadence of modern democracy (AGAMBEN), and visible features in the current treatment given in Brazil to issue of smoking (SILVA), as well as urbanistic projects such as the case of Luz district in São Paulo (LEITE & CASTRO). In this sense, it leads us to question about what is prohibited, about who actually suffers the punishment, in short, about what do we really take care when we take into account the Unheimlich (FREUD) and other social interdicts (BATAILLE).
