Abstract

A technology of forming a discrete diffusion oxide layer on the material surface is suggested. Research data for the metallographic and mechanical properties of alloyed construction steels subjected to discrete diffusion oxidation are presented. Mechanical investigations show that the microhardness of oxidized alloyed construction steel is five times higher than that of the as-prepared material and exceeds the microhardness of nitrided steel by a factor of 1.5. The rise in microhardness and rigidity is explained by the presence of iron oxide in the coating.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
