The present study deals with improving the material characteristics of Al using plasma coating. Since the melting point temperature of the Al is 660°C, using plasma coating 0.25mm of ZrO2 is coated on Al and NiCrAlY is used as bonding material between Al and ZrO2. By scanning electron microscope we can observe difference of microstructure of coated and uncoated material. It is found that porosity on 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, it is found that using ZrO2 the hardness of base material is improved by 26.52%. Corrosion test was carried using Na2SO4 and V2O5 salts (byproducts of combustion), it is found that ZrO2 has better resistive capabilities towards corrosion. At thickness of 0.25mm for the coated material it is found that thermal stability of base Al material has increased twice compare to the actual value. It can withstand up to 1000°C without any degradation of coated material. Using zirconium dioxide as coated material on aluminium the mechanical properties of the base material is improved.
