| Abstract Scope |
In this work, wear-resistant coatings for parts operating in aggressive environments of metallurgical production were obtained. The process was carried out using composite saturation charges. The following powders were used as a transport agent: NH4Cl, NaF, NH4F, AlF3, NaCl, NH4I, Na3AlF6, CaF2. The results of the wear test under sliding friction conditions on the SMT-1 friction machine show that the best performance is obtained with vanadium, titanium, boron, and alitized coatings, the wear value of which (ΔI) is 30-10-4, 60-10-4, 90-10-4, and 110-10-4 g/m2, respectively. The data obtained for comparing wear resistance show that with a higher value of residual compressive stresses at vanadium (350-420 MPa), boron (320-380 MPa), titanium (240-320 MPa), and alitized (240-310 MPa) coatings, compared to other studied coatings, their wear resistance is higher. |
