The present study deals with the material characteristics of Aluminium using plasma coating. Ceramic coating on various parts of an IC engine provides excellent thermal barrier properties which are used in preventing the heat loss during the working cycle. Since melting point of Al is 650°C, using plasma coating, 0.35mm of ZrO2 is coated on Al and NiCrAlY is used as bonding material between Al and ZrO2. Using scanning electron microscope, microstructure of coated and uncoated is studied and found that porosity on the coated material was less and the surface was slightly abrasive. Hardness test is carried out on coated and uncoated material at various points on the surface and found that using ZrO2, hardness of the base material improved by 29.13%. Corrosion test was also carried out using Na2SO4 and V2O5 salts (by-products of combustion) and found that ZrO2 has better resistive capabilities towards corrosion than uncoated. At a thickness of 0.35mm for the coated material, it is found that thermal stability of base Al material has increased twice compared to the actual value.
