Corrosion-fatigue failure of tractor trailers metal materials in aggressive environments
Autor: L. Poberezhna, Y. Koval, L. Poberezhny, I. Murovanyi, A. Hrytsanchuk, P. Popovych, O. Shevchuk
Publikováno v: Koroze a Ochrana Materialu, Vol 64, Iss 2, Pp 45-51 (2020)
The processes of corrosion-fatigue failure of materials in contact with mineral fertilizers are insufficiently studied. As a result of joint influence of atmospheric corrosion and mechanical loads, about 70 to 80 % of machine parts get out of order,
