| Popis: | We study the corrosion resistance of coatings obtained by submerged-arc built-up welding. The fused metal is obtained from Fe-based flux-core wires of the Kh10R4G2S grade. On the basis of the results of phase analysis, it was discovered that the fused metal is formed by a FeCr matrix and a solid solution of Fe2B and (FeCr)B borides. This observation was confirmed by the data of spectral analysis. It is demonstrated that the application of horizontal vibration with an amplitude of 300 μm in the course of surfacing leads to the dispersion of the Fe2B and (FeCr)B boride phases down to 2–5 μm2, which increases the resistance of fused metal to abrasive wear. The mass losses in the cases of wear with fixed and nonfixed abrasives are made 2–2.5 times lower. It is also shown that the procedure of surfacing performed in the presence of vibration negatively affects the corrosion resistance of the welded metal obtained from Kh10R4G2S flux-core wires due to the increase in the fracture of cathodic inclusions. |
