| Abstract Scope |
In a previous study, the laser-deposited Cu-based and Ti-based High Entropy Alloys showed promising mechanical properties for aerospace applications after using preheating temperature at 400℃ as the laser parameter's optimization tool. Using the optimized laser parameters, this study examines the thermal behaviour and the corrosion responses of high entropy alloys in 3.5 wt.% H2SO4 solution at room temperature using a thermogravimetric analyzer and Potentiodynamic polarization, respectively. The influence of the laser processing parameter and the compositional variations of the high entropy alloys were investigated. The results showed that the high entropy alloys were thermally stable with an increase in laser power and energy density, the Cu-based laser-deposited high entropy alloy showed better corrosion resistance than the Ti-based laser-deposited high Entropy alloy and the conventional arc-melted Cu-based amalgams from literature. |
