Abstract: In-situ synthesis is a process of developing high-performance material with the minimal reinforcement ratio. In this work dry sliding friction and wear behaviour of AA6061 - TiB₂/ZrB₂ in-situ metal matrix composites are investigated by using pin on disc wear testing machine against high chromium steel counter face at room temperature. The influences of normal load, sliding speed and reinforcement ratio on wear properties are studied. Wear transition maps are generated to establish the scheme of the wear rate and wears transition for a particular sliding condition. Worn-out surface analysis also carried out to study the debris layer formation on the sliding surfaces. Experimental investigation shows that normal load, sliding velocity and reinforcement ratio offer significant influence on wear performance.
