Investigation of the abrasive wear resistance of carburised and boron-enriched protective layers exposed to different stresses

The possibility of using boron-enriched protective layers instead of conventional carburised layers is investigated. Experimental investigations have been carried out on worm presses for oil extraction. It was found that the operation of worm presses with boron-enriched layers, although having higher hardness values, display lower wear and tear resistance compared with those of carburised components. The conclusion is that the wear of protective layers exposed to abrasive action under conditions of changing pressure and abrasive action depends on the hardness of the surface layer, on the quality of the underlayer, and the level and type of contact pressure on the mechanical component.
