Gas-Shielded Tungsten Arc Welding (GTAW) was modified to a Flux-Cored-Double-Wire GTAW (FCDW-GTAW); in this technique, wires of different compositions are used simultaneously obtain microstructures. In the GTAW, automatic flux-cored double-wire with combination four deposited AISI1020 steel, allowing Pin-on-disk wear tests described by ASTM G99 evaluate coefficients hardfacing materials combini...

Purpose: Purpose of this paper is investigation of influence of the surface processing by laser method on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds were tested for three cases: without additional pr...

This study explores the use of powder plasma transferred arc welding (PPTAW) as a surface layers deposition technology to form hardfaced coatings improve upon wear resistance non-alloy structural steel. Hardfaced layers/coatings were prepared using PPTAW process with two different wear-resistant powders: PG 6503 (NiSiB+60% WC) and PE 8214 (NiCrSiB+45% WC). By varying parameters gas flow rate (P...

The wearing of cutting tools is a bottleneck many branches in the industry. However, used mining sector are extraordinarily prone to rapid deterioration since rocks exhibit aggressive abrasive properties. A typical example fast tool conical pick. It industry and other businesses requiring rock cutting, such as roadworks tunnelling. Both manufacturers users attempt find way enhance lifespan work...
