Abstract: The components used in the mining and construction industry, agriculture, etc., during its lifetime are exposed to the various types of wear, which include abrasion, erosion, impacts, and others. Currently, there are several variants of protective surface layers which are wear resistance. [..] Read more

Abstract: Determination of corrosion rate by means of electrochemical methods such as polarization resistance is limited to open-circuit conditions. In the case of cathodic protection, a protected object is polarized to protection potential by means of negative total current, the value of which is thus useless for quantifying corrosion rate.
