Abstract
Streszczenie
W artykule porównano wyniki badań dotyczących właściwości eksploatacyjnych powłok ceramicznych natryskiwanych płomieniowo, materiałami ceramicznymi tlenkowymi w postaci proszku na osnowie tlenku aluminium Al2O3 oraz tlenku cyrkonu ZrO2, na podłoże z konstrukcyjnej stali niestopowej S235JR. Oceny dokonano w oparciu o badania metalograficzne, przyczepno- ści powłoki do podłoża, odporności na ścieranie, odporności na zużycie erozyjne oraz udar cieplny.
Abstract
This article compares the results of studies on the operational properties of the flame sprayed ceramic coatings, ceramics oxide powder on the base of aluminum oxide and zirconium oxide Al2O3 ZrO2, on the ground of non-alloy structural steel S235JR. The assessments were based on metallographic examination, the adhesion, abrasion resistance, resistance to erosive wear and thermal shock.
