FLUX-CORED WIRES PROVIDING DEPOSITED METAL WITH HIGH RESISTANCE TO ADHESION WEAR.

- Abstract
PWI developed flux-cored wires providing deposited metal with sulphide or graphite inclusions, which have the role of solid lubricant and prevent adhesion wear. Comparative studies of heat- and wear resistance at metal-to-metal friction at room and elevated temperatures showed that PP-Np-20Kh5M3FS(S) flux-cored wire can be recommended for welding parts operating under the conditions of increased mechanical loads and moderate cyclic thermal loads. PP-Np-50Kh9S3G(S) flux-cored wire providing deposited metal with high adhesion wear resistance at room temperature can be successfully used for surfacing parts of heavy-duty friction pairs. Having relatively low cost, but requiring application of complex surfacing technology, PP-Np-150S2Yu flux-cored wire can find limited application in surfacing friction pair parts operating at high mechanical loads in the case, if it is cost-effective.
