Abstract

Boriding is used to increase the operational durability for various kinds of tools and industrial equipment. Boride coatings have quite a few advantages. These include high hardness, wear resistance, heat resistance, corrosion resistance, etc. High hardness and wear resistance are the predominant of these properties.

In most cases, the destruction of parts and tools begins with surface layers having a depth of thousandths to hundredths of a millimeter. Therefore, the wear resistance of parts subjected to boriding is determined not so much by the depth of the boride coating as by its quality and structure.

This article discusses the study of the formation of structure and properties on tool steels У12, 5ХНМ, 7Х3. In this work, a metallographic analysis of boride coatings on steels was carried out. The microhardness was determined by the depth of the diffusion coating depending on the steel grade. Tests for heat resistance and a comparative analysis of the wear resistance of steels subjected to heat treatment and boriding were carried out. An assessment of the possibility of using boriding for these steels is given.
