The research consisted in obtaining Ni-P and Ni-P-Al2O3 coatings followed by heat treatment and characterization of heat treated and untreated layers. The layers were deposited on the steel strip, by electroless method to certain process parameters. To obtain the Ni-P-Al2O3 nanocomposite layers, 5 g/L Al2O3 particles of 20 nm were introduced into the nickel bath, and it has been worked with the same parameters as to obtain the Ni-P layer. The samples were heat treated at 300 0C, 400 0C and 5000C for one hour in a ...
