Abstract:

Purpose. To clarify the dependence of the corrosion resistance and durability of coatings on their basic physical properties on the basis of a thermodynamic model. To carry out an experimental study of corrosion and strength characteristics of multi-coatings covering the parts of mining equipment.

Methodology. Elementary carriers of corrosion, thermal and brittle fracture are considered as a system of non-interacting particles immersed in a thermostat. The response function of the subsystem of elementary carriers of the destruction to the external field was derived through the methods of nonequilibrium statistical thermodynamics.

When coating, the cathodes prepared by induction melting were used. The quantitative analysis of the elemental composition of composite cathodes was held with the JEOL JSM-5910 electron microscope. To measure the microhardness the HVS-1000A micro durometer was used. Determination of corrosion rate in different technological environments was conducted in accordance with GOST 9.908-8512. To determine the corrosion resistance of the coatings we used the method of anodic polarizing initiation of defects (APID).

Findings. A relation between the rate of corrosion, the surface tension of metal coatings and their melting point was obtained. The formula describing the strain state of a rigid body, including the area of destruction, was derived. The corrosion resistance and strength characteristics of composite coatings on parts of mining equipment were experimentally determined.

Originality. The dependence of the corrosion resistance, durability of coatings on their surface tension and melting point was obtained.

Practical value. The resulting formula can be used for qualitative analysis and prediction of the rate of destruction and metal coatings under corrosion, deformation and thermal influences.
