Effects of Load and Sliding Speed on Tribological Behavior of Plasma Sprayed Bronze-Alumina Coatings
Bronze alloys are widely used in different tribological applications including sliding components. Bronze-Alumina composites have been attracting the interest of researchers in recent years. Among the most recent surface modifications techniques, plasma spraying has been successfully applied to these coatings. In this investigation, an attempt has been made to analyze the sliding wear response of Bronze-Alumina coats over a range of applied pressures and sliding speeds. It was observed that an increase in applied load causes more weight losses in wear test while increasing the sliding speed led to no further losses at this variables range. Wear processes and mechanisms of these behaviors are discussed in the light of the microstructural observations combined with wear surfaces and debris particles examinations.
