PHASE EVALUATION OF FEBNICR WELD DEPOSIT WITH ADDED TUNGSTEN CARBIDE PARTICLES

Popis výsledku v původním jazyce

Hard particles used in combination with iron-based matrix are applied in a wide range of areas. It is used for screw conveyors, de-baler knives or mining gear teeth. The weld deposits can be used both in the production of these machine parts and in their later repair to increase their service life. The paper deals with the analysis of microstructures produced in the weld deposits combining martensitic matrix and 1-2 mm tungsten carbide particles. The investigated weld deposit was performed by welding technology using filled electrode Megafil A864M in a mixed gas atmosphere (Ar + N). Tungsten carbide particles were added due the vibratory feeder. Steel S690QL was used as a parent material. The research focuses mainly on the microstructure analysis by electron microscopy (SEM) and the investigation of individual phases by diffraction analysis XRD. Using point chemical analysis, the movement of individual chemical elements between the base material, the weld deposit and the tungsten carbide particles was examined. Part of this paper is focused also on SEM investigation of worn surface of the weld deposit.
