STUDY OF ELECTROCHEMICAL BEHAVIOR AND SMOOTHING OF ADVANCED ALLOY TI6AL4V WITH ULTRASONIC WAVES

Abstract

This research deals with the electrochemical behavior of the advanced material Ti6Al4V in 5% NaCl electrolyte solution as well as the smoothing of the semi-finished front surface by the ultrasonic cyclic stress-inducing effect on the microgeometry peaks. Laboratory experiments were carried out on the estimation of electrochemical parameters in relation to the studied material. The smoothing of the front surface was made by varying the distance between it and the end of the ultrasonic chain and also the energy consumption on the ultrasonic chain. Computerized models were developed using the finite element method of the material removal mechanism using ultrasounds, aiming to explain the specific phenomena of ultrasonic cavity in electrolytic environment.
