Computer vision for determination of degradation factor in biocompatible alloys

Abstract:

The degradation factor of a biocompatible alloy, AISI 316LVM, was determined by computer vision. For this, a simulated physiological solution (Hanks' solution) which simulates the electrolyte composition in the body, that is the environment in which the implant is used. The electrochemical behavior was evaluated by potentio-dynamic curves. The surface characterization was performed using a stereoscope and corrosion products were evaluated by X-ray diffraction. The system used a microscopic image of the surface of the material in its natural state (mirror finish) as a basis for comparison parameter to define what state are once samples have undergone testing. It was found that it is possible to estimate the factor of degradation or deterioration of a material through a topographic analysis.
