Abstract
The analyzed topic refers to the wear resistance and friction coefficient changes resulting from heat treatment (HT) of a hot-dip zinc coating deposited on steel. The aim of research was to evaluate the coating behavior during dry friction after HT as a result of microstructure changes and increase the coating hardness. The HT parameters should be determined by taking into consideration, on the one hand, coating wear resistance and, on the other hand, its anticorrosion properties. A hot-dip zinc coating was deposited in industrial conditions (according EN ISO 10684) on disc-shaped samples and the chosen bolts. The achieved results were assessed on the basis of tribological tests (T11 pin-on-disc tester, Schatz®Analyse device, Sindelfingen, Germany), microscopic observations (with the use of optical and scanning microscopy), EDS (point and linear) analysis, and microhardness measurements. It is proved that properly applied HT of a hot-dip zinc coating results in changes in the coating’s microstructure, hardness, friction coefficient, and wear resistance.

Materials 2021, 14, x FOR PEER REVIEW. According to a report by the International Lead and Zinc Study Group [1], the global zinc production in 2016–2019 amounted to more than 13 million tons yearly, and more than half of these resources were used to protect steel from corrosion in galvanic processes. This is an up-to-date, highly popular, and trusted technology [2,3]. The development of the industry and, as a consequence, the growing needs of new applications determine continuous technological progress
