| Abstract: |
| Objective To investigate the wear resistance at high temperature of H13 steel by RE-N-C-S-V-Nb multicomponent permeating treatment, in order to provide new technology to avoid premature wear of aluminum extrusion die. Methods The high temperature wear property of compound deposition samples and control samples was tested and then the samples were detected by means of optical microscopy (OM), scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS), and X-ray diffraction. Results It was found that quenched samples and tufftriding samples all had severe abrasive wear and adhesive wear phenomenon, microcracks appeared on the permeation layer, the high temperature friction coefficient curve had obvious fluctuations and peaks, the high temperature wear rate for the two kinds of samples was respectively at 21. 20×10-13,11. 30×10-13 m3 / (N·m), The microhardness at 584HV0. 1 and 1018HV0. 1 after incubation for 4 h at 560 ℃. The RE-N-C-S-V-Nb compound deposition sample had mostly micro oxidation wear and adhesive wear, no microcracks appeared on the permeation layer, the high temperature friction coefficient curve was gentle, the high temperature wear rate was only up to 2. 96×10 -13 m3 / (N·m), 1334HV0. 1 at microhardness. Conclusion H13 steel after RE-N-C-S-V-Nb multi-element penetrating has a strong high-temperature wear resistance. |
