The corrosion of implant biomaterials is a well-known critical issue when they are in contact with biological fluids. Therefore, the reactivity of Ti6Al4V implant biomaterials is monitored during immersion in a Hanks’ physiological solution without and with added metabolic compounds, such as lactic acid, hydrogen peroxide, and a mixture of the two. Electrochemical characterization is done by measuring the open circuit potential and electrochemical impedance spectroscopy performed at different intervals of time. Electrochemical results were completed by morphological and compositional analyses as well as X-ray diffraction before and after immersion in these solutions. The results indicate a strong effect from the inflammatory product and the synergistic effect of the metabolic lactic acid and hydrogen peroxide inflammatory compound on the reactivity and corrosion resistance of an implant titanium alloy.

During surgical operations in the eye, metallic materials may come in contact with tears. These metals/alloys may undergo corrosion when they contact the tears. The corrosion resistance of a Ni-Cr alloy in artificial tears in the presence of excess of glucose and sodium chloride has been evaluated by electrochemical studies such as polarization study and AC impedance spectroscopy. It is observed that when the sodium chloride level or glucose level in tears increases, the corrosion resistance of Ni-Cr alloy in artificial tears is not affected. It is interesting to note that the corrosion resistance of Ni-Cr alloy in artificial tears rather increases. Hence when there is an increase in glucose level of sodium chloride level in tears, the surgical instruments may be of Ni-Cr alloy.

“…These equations are practically empirical equations because they use correction coefficients depending on various situations (composition, temperature, etc.) All models used are regressive, some simple are based on linear or nonlinear regression equations [4,5], and some more appreciated using neural networks [6][7][8].…”

The controlled lamination of thick sheets involves the use of algorithms for choosing the rolling parameters: the initial heating temperature, the lamination scheme (the distribution of the total thickness reduction on each rolling cage, the number of passes through each cage and the distribution of the thickness reduction on each passage, intermediate cooling - cooling time and speed), and the temperature of the product obtained at the end of the rolling. The complexity of the phenomena, which occur during the hot plastic deformation process and which must be sufficiently well mastered in order to obtain reproducibly the technical specifications imposed on the products with different destinations, is the justification for this work. The data provided by Arcelor-Mittal Galati was used to obtain the mathematical model. Equations that correlate the main mechanical characteristics with the chemical composition of the steel and the parameters of the hot rolling pattern used are presented.
