Popis: | The effect of electrospark alloying (ESA) steel 40Kh with AlN ― ZrB2 ― ZrSi2 electrode material on the surface composition, structure, high temperature resistance to corrosion in air, anodic oxidation in a 3.0% NaCl solution, and also on the tribological properties was investigated. It was found that ESA substantially increases the corrosion resistance of the steel, and decreases the wear rate by an order of magnitude. The mechanism of corrosion of the ESA coating on steel 40Kh was determined. The corrosion process was retarded mainly by the presence of an Fe2O3 ― Al2O3 solid solution alloyed with chromium in the coating. |
