Abstract

The influence of nitrogenization on steel 08Х18Н10 structure, hardness and wear resistance in subnormal discharge is investigated. Due to metallographic, roentgen and microroentgen-spectral analysis application it is established that increase of processing time in the upper part of nitride zone influence on nitride dissociation processes followed by reduction of hardness. The industrial tests showed that the nitrogenization enables to increase coal concentrate dewatering screen resistance in 1.5-2 times.
