Aluminum alloys, particularly Al7075, are integral to numerous engineering applications due to their favorable mechanical properties. However, understanding their tribologicalbehavior under varied operating conditions remains crucial for optimizing performance and extending lifespan. This study investigates the influence of the alloying element Ky on the tribological properties of Al7075 alloy through a comprehensive experimental approach. Tests were conducted under diverse conditions, including varying sliding distance, speed, load, and temperature. Results indicate that Ky addition enhances wear resistance and reduces friction coefficients, attributed to grain refinement and intermetallic phase formation. Analysis of wear behavior and friction trends provides insights into underlying mechanisms and validates theoretical predictions. These findings have significant implications for engineering applications, guiding the design of more reliable and durable mechanical systems. Further research avenues include exploring synergistic effects of alloying elements and refining testing protocols for enhanced data interpretation. This study contributes to advancing knowledge in tribology and materials science, facilitating the development of optimized aluminum alloy components for various industrial sectors.
