Abstract
This paper presents the results of a study analysing the influence of the microstructure of a chromosiliconized layer produced using C90U steel on the tribocorrosive properties exposed to mine water. The steel coating process was conducted at a temperature of 1000°C for 8 hours. The layer was prepared by the powderpack method with the use of powdered ferrochrome with SiC, kaolin powder, and ammonium chloride as the activator. Samples of C90U steel were placed in the powder mixture inside specially designed boxes of X6CrNiTi18-10 steel and were heated in a laboratory furnace. The boxes were closed and sealed hermetically with enamel to prevent charge oxidation. The microstructure, chemical and phase composition of the chromosiliconized layer were analysed. Thickness, porosity, and hardness were measured. The wear of the chromosiliconized layer resulting from exposure to a corrosive environment of model mine water was analysed. A tribocorrosion test was conducted with the use of a wear tester composed of three rollers and a cone. The chromosiliconized layer produced by the powder-pack method on C90U steel contributed to an increase in the hardness of friction systems exposed to a corrosive medium in comparison with uncoated steel.
