A Review on Corrosion Behavior of Nickel Matrix Composites

Nickel in elemental form or alloyed with other metals or materials has made significant contribution to our present day society. Nickel and nickel alloys are the class of advanced material that are are identified as candidate materials for marine applications and vitally important to aerospace, automotive industries because of their ability to withstand a wide variety of severe operating conditions involving high temperatures, corrosive environments, high stresses, strength, toughness, metallurgical stability, and combinations of these factors. The demand for such functional material to provide high performance has resulted in continuous attempts being made particularly in areas of alloy design and the use of novel processing techniques to develop composites or hybrid materials as serious competitors to the traditional engineering alloys. Also a simple and cost effective method for manufacturing of the composites is very essential for expanding their application. Metal matrix composites (MMCs) offer designers many benefits as they are particularly suited for applications requiring good strength at high temperature, good structural rigidity, excellent corrosion resistance, and light weight. This paper presents a review on the corrosion behaviour of Nickel matrix composites containing single and multiple reinforcement.
