"TRIBAN 19-20"

TRIBAN-EFFECT OF TEMPERATURE ON TRIBOLOGICAL BEHAVIOR WITH THE MORPHOLOGY OF ANODIC LAYERS.




DESCRIPTION

The project aims to establish knowledge bases on the behavior of the anodic layers against various temperatures, from the point of view of mechanical properties, specifically on the wear resistance of these layers, thereby increasing the knowledge of the behavior of the anodic layers against temperatures, especially at medium and high temperatures.

OBJECTIVES

• Development of structural and ordered anodic layers, with improved properties compared to conventional ones in terms of their tribological behavior in temperature gradients.
• Generation of conventional anodic layers, double anodized and by pulsating current, as comparative techniques.
• Relate the generation of the previous anodic layers with other factors such as current, time, temperature, electrolyte, sealing, etc.
• Relate the tribological properties with the morphology and composition of the anodic layers.
• Analyze the tribological behavior of the anodic layers taking into account the thickness of the anodic layer, applied load, wear rate and variation of the wear temperature.
• Observe how they affect the change in load and temperature (up to a maximum of 400 ºC), in the tribological behavior, taking into account the conditions of generation of the anodic layer.

RESULTS OBTAINED

Year 2020: In the development of the layers, several points to be highlighted have been observed. The homogeneity of the anode layer improves at a lower temperature for the same voltage, taking into account a voltage range. The presence of the additive and a polished surface improves the homogeneity of the anode layer. We have related homogeneity to porosity, smaller pore sizes clearly influencing the friction coefficient and wear rate. The coefficient of friction decreases with the homogeneity of the anodic layer, hence it decreases with the presence of additive, a lower anodizing temperature, polished surface and also with double anodizing. The wear rate is influenced by the anodizing temperature, the higher the higher the temperature. It is minor with a polished surface. It also improves with the presence of additive and double anodizing. Tribological tests at high temperatures show that the wear rate increases considerably, but that the presence of additive and double anodizing improves it significantly. On the other hand, it has been found that the presence of additive in a proportion of 2% is the one that has given the best results. Corrosive behavior improves with time (thicker), lower temperatures, with the presence of the additive, and with double anodizing. The wear marks show microcracks due to the presence of shear stresses during the friction test, being wear due to deformation of the anodic layer, flaking with microcracking.
