| Abstract | ||
| In this study an electroplating method has been employed (with zinc, nickle). Studying of mechanical, surface, metallurgical properties for each coated systems and made a comparison among them and with shoot penned coated systems. Low carbon steel alloy has been selected as a substrate. Studying of specified properties including coating thickness and dry corrosion properties (oxidation at high temperature) and comparison the results of each treatment with other treatment results. Coated samples with nickel and zinc by electroplating methods are used in order to compare among the resulting coating layer properties. Shoot penning method also has been employed to the two coatings in order to determine the compression residual stresses role in the variation of studied properties. Results showed that nickel coating layer has higher oxidation resistance than zinc coating layer at high temperature, but has lower roughness, micro hardness, wear resistance and density. Microstructure inspection results showed ferrite- pearlite phases in the treated samples for all coated systems, This ensures that this treatment will not subject to any phases transformation, and formation of coating layer with a different thickness as illustrated by micro structure images. | ||
