In this investigation an attempt has been made to fabricate Al-SiC p and Al-Al2O3 composite materials by powder metallurgy technique at different volume percentage of reinforcement (5, 10, 15, 20, and 25%). The corrosion behavior of the composites were analyzed using AC Gill potentiostat with 3.5 wt% NaCl medium. Four factor, five level, central composite, rotatable design matrix is used to optimize the required number of experiments. The mathematical models were developed by the response surface method (RSM). The developed models have been checked for their adequacy and significance by the F-test and t-test, respectively. The results obtained from the mathematical models have been optimized and also tested using conformity test runs.

The composites are classified as metal matrix composites, polymer matrix composites, and ceramic matrix composites. Many different matrices have been tried over the years in the MMC formulations but aluminum has been most exploited for compositing due to its low density and ease of fabrication. These composites have received considerable attention as a potential advanced material for application in automobile, aerospace, defense, and general engineering sectors. In this investigation, an attempt has been made to fabricate Al-SiC p composite material by powder metallurgy technique at different volume percentage of reinforcements (5, 10, 15, 20, and 25%). The corrosion behavior of the composite was analyzed using AC Gill potentiostat with 3.5 wt% NaCl medium. Four factors, five levels, and a central composite rotatable design matrix is used to minimize the required number of experiments. The effect of metallurgical factors on the corrosion behavior of the composite was analyzed. The factors include volume percentage of reinforcement, particle size, pH, and reverse potential.
