Influence of Nickel & Manganese Particles on Copper Metal Matrix Composite for Heat Exchanger Tubes

Composites are ideal for applications in corrosive environments such as marine applications. The main reason for composite materials used in marine structures as their high specific properties, with their corrosion resistance and lightweighting attributes. Metal matrix composite materials are widely used in various marine applications due to good durability in sea water superior performance. And also due to the ability to withstand saline water. Cu-Ni alloys were widely consumed process of removing salt from seawater. This technology has used in various fields such as marine, power stations, automobiles, aircraft, etc. Metal matrix composite is prepared by powder metallurgy technique. In terms of varying, the percentage of reinforcement such as nickel and manganese particles with copper alloys have good work hardening. The salt spray test was studied in this paper to find a corrosion behavior of MMC and to determine the corrosion rate by calculating the weight reduction of the material. It seems that manganese composite expressed tremendous corrosion when dipping in a 5% sodium chloride solution.
