Abstract

One of the surface hardening methods of iron-carbon alloys, namely chemical-heat treatment using a vapor-gas saturation medium was studied in the paper.

The conducted researches suggest that ascending diffusion of carbon takes place during the surface layer formation in the vapor-gas medium due to the disintegration of the lamellar structure of pearlite cementite and crushing of plates of graphite inclusions of cast iron with its accumulation on the layer surface. These processes are inevitable for iron-carbon alloys in isothermal conditions with the presence of vapor-gas redox medium.

It is proved that the main graphite shape change stimulators in cast irons are calcium, magnesium and oxygen, present in the saturation medium, and the free carbon content in the modified surface layer will give it new properties.

Considering the obtained results, operational characteristics of the obtained layer, namely wear resistance and antifriction properties were also investigated.

The samples, processed in the atmosphere of the superheated steam of aqueous solution of salts, containing such chemical elements as sulfur, oxygen, molybdenum, nitrogen or nitrogen, phosphorus, oxygen were tested in the laboratory.

It was revealed that using the superheated steam of aqueous solution of salts, containing such elements as sulfur, molybdenum, oxygen, phosphorus as saturation medium allows to reduce the friction coefficient value of the iron oxide layer at increasing its score-resistance and, as a result, increase operational properties of parts and units of machines and mechanisms, operating in friction conditions.
