  Przedstawiono uszkodzenia stopu niklu typu 825 w wyniku eksploatacji w chłodnicy powietrznej za reaktorem wodorowym w rafineryjnej instalacji przepracowanych olejów napędowych. Wyjaśnono korozyjno-erozyjny mechanizm niszczenia, zwracając uwagę na kruchość materiału w obecności wodoru i udarowego działania strumieni procesowych.

  The project involved designing, constructing and commissioning a cathodic protection system for a selected spiral classifier operating at the KGHM Polska Miedź S.A. Ore Concentration Plant (O/ZWR). The authors developed a concept and assumptions regarding the corrosion protection of a large industrial device using a cathodic protection system with an external power source. Pre-project studies included conducting a trial polarization...

  - Coatings - Year 2021

  A study was carried out to select the appropriate coatings for corrosion protection of the spiral classifier working at KGHM Polska Miedź S.A. Ore Concentration Plant. The abrasion resistance of selected protective coatings and wear-resistant linings was investigated using a DT-523 rotary abrasion tester with Taber CS-10 rubber abrasive discs. The average weight loss of the coatings after a cycle of 2000 revolutions was determined....
