Abstract: In this paper an attempt has been made to review machining characteristics, tribological and corrosion behaviour of aluminum alloy 7075 hybrid composite utilizing different types of reinforcements. Many investigations revealed that application of various new techniques like friction stir processing, electric discharge machining and abrasive water jet machining are found to be the successful for enhancing the machining characteristics of hybrid composite. It was found in many researches that the introduction of hard ceramic phase with soft reinforcement phase into the matrix improves the tribological characteristics along with other mechanical properties. The corrosion rate was found to be higher for the composite with poor interface between matrix and reinforcement. Also, many researchers reported about the enhancement of corrosion resistance due to heat treatment, employing friction stir processing technique and optimized addition of reinforcement.
Keywords: Hybrid metal matrix composite, AA7075, machining characteristics, wear, corrosion.
