摘要

The advantages of inhibited polyethylene Zerust films for inter-operational protection of steel wires with different initial surface treatments are demonstrated based on tests carried out in a climatic chamber in a model salt fog environment (30 days) and macroclimatic bench tests in a temperate climate zone (135 days). The exposure time of protected samples in an active environment influences the appearance of the first traces of corrosion, and their further increase is studied. The areas of corrosion damage are determined. It was established that, according to a 10-point scale, the effectiveness of protecting non-heat-treated and zinc-coated wires with Zerust films is 8–10 points. Protection with uninhibited polyethylene films is 3 points. It is shown that the protection of heat-treated wires with the studied films is low (1–3 points) and it is short-term, which makes them unacceptable for independent use. Comparative characteristics of uninhibited and inhibited polyethylene films’ protective ability are obtained, and recommendations for their use in inter-operational protection of steel wires with different initial surface treatments are developed.
