Summary:Weld deposits are one of the most used economical ways of the wear resistance increase. The study compares the characteristics of the overlay material welded-on and the abrasive wear resistance. The research has been carried out using hardfacing alloys reinforced with primary chromium carbides and complex carbides. The overlay material was deposited on the low-carbon steel S235JR using the gas metal arc welding (GMAW) method. Four different commercial overlay materials were studied in terms of the microstructure effect. The abrasion wear testing was carried out using the abrasive cloth of grit 120 according to CSN 01 5084. The microstructure characterisation and surface analysis were made using optical and scanning electron microscopy. The results illustrate a significant effect of primary carbides on the abrasive wear resistance of weld deposits.
