摘要
The paper attempts to determine the influence of high temperature oxidation as a method of preparing the surface of gray cast iron grade GJL-250 on the mechanical properties of the zinc coating obtained by the method of: hot-dip, galvanic and lamella. Samples for testing were taken from parts used for the construction of overhead power lines. Intensity of wear of the zinc coating was determined by tribological tests under dry friction conditions, which were made using the T-11 tester. The research allowed to determine the coefficient of friction of the zinc coating depending on the method of preparation of the surface on which they were applied. In addition, macroscopic and microscopic analysis was performed to determine the mechanisms of shell damage and measurements of the geometric structure of the surface were made. On the basis of the obtained test results, the differentiation of the degree of wear of the obtained coatings was determined depending on the method of surface preparation. The conducted research has shown that the use of high temperature oxidation as a way of preparing the surface of gray iron can be a tribological characteristic of the zinc coating.
