The Influence of Carbon, Carbon,
and Boron on the Formation of Diffusion
Nanocomposite Hardened Layers
on the Surfaces of Steel Parts
Andrew E. Stetsko and Yaryna T. Stetsko
1 Introduction
The main task of chemical–thermal treatment of steel parts is to increase their
resource. Surface hardening gives a significant reinforcing effect on conventional
structural steels: increasing strength, hardness, and durability. The core of such parts
remains soft—resistant to dynamic influences. Also, the price of such parts made of
structural steel is low.
The method of chemical deposition and diffusion of boron and carbon forms is
done on the parts made of morphology steel having a reinforced layer of thickness
500 microns and microhardness of 14 GPa. The stability of these parts after chemical
deposition and diffusion boron and carbon increases by 2–3 times.
Objective: Method for strengthening steel surfaces of friction pairs by chemical sedimentation and diffusion of boron and carbon that provides strength to
manufacture or restore detailed machines.
2 Materials and Methods
Conducted of investigating the diffusion of carbon in the iron sheet during the decarburization of the gas in a solid atmosphere in a weak oxidizing atmosphere (Ar + H 2 +
H 2 O), the microstructures of the iron sheets after bleaching were discovered through
SEM [1]. This discovery found a carbon gradient after the discoloration of iron sheet
