Abstract
The main objective of this research is to acquire high tribological surface properties by improving the hardness and erosion resistance of alloy 2024, and to study the effect of heat and surface treatments on the hardness and erosion properties. Several heat and surface treatments were applied. These treatments are annealing, solution and aging treatment, plasma nitriding, and duplex surface treatment, which includes plasma sputtering followed by plasma nitridation. The microstructure, hardness and mechanical wear resistance of this alloy were checked before and after each treatment. An erosion tester was manufactured locally to measure the wear resistance of this alloy. X-ray diffraction, scanning electron microscopy, and Vickers hardness were used to characterize the results. The results showed that each treatment differently affects the microstructure, wear resistance and hardness of this alloy.
The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.
