Electrolytic coating of iron-chromium alloy of sulphate-chloride electrolyte in machine parts recovery process modelling

Introduction. The technological process of restoring a part should provide more than 80% the resource and no 50% cost new part. wear resistance applied coating determines restored operating under waterjet boundary friction. microhardness an iron-based electrolytic is one key indicators resistance. study results statistical processing factors most affecting increase in will make it possible to recommend optimize deposition conditions for obtaining wear-resistant coatings. Materials methods. studies on equipment that let obtain necessary data with required accuracy were carried out. mathematical using modern tools excluded errors, dependence was Results . During developed sulfate-chloride electrolyte iron–chromium coating, became determine effect – ‘factors’ (temperature, acidity electrolyte, cathode current density) ‘response’. It found combination ‘temperature’ ‘cathode density’ coded values 1.5. 2.0 -2 are significant. order maximum optimized. Discussion conclusions. As result conducted Fe-Cr alloy from high-quality coatings iron-chromium high microhardness, strictly comply requirements greater extent. density temperature compared iron baths installed regulated by equipment.
