The thickness of the diffusion layers was studied, along with the phases and the microstructure and
composition, across the depth in diffusion zone. The obtained results proved the effect of nitriding
system in the growth of the diffusion layers on
surface of double composite martensitic - austenitic alloy
steel.
Analysis of mechanical and tribological characteristics of treated double composite steel under dry
friction was also studied. It was found that diffusion treatment had a significant influence on work
capacity of tested alloy. Stability of alloy after nitriding was (2.5-4) times higher in magnitude
compared to untreated alloy.
