Abstract
W pracy przedstawiono wyniki badań rozkładu naprężeń i temperatury podczas procesu natryskiwania powłoki metalicznej Ti na podłoże ceramiczne Al2O3 oraz metalowe w postaci żelaza Armco. Zbudowano model MES dynamicznego uderzenia cząstki Ti w podłoże i analizowano przemieszczenie cząstki w głąb podłoża. Podczas zagłębiania się cząstki analizowano zmiany czasowe naprężeń i temperatury w wybranych punktach z obszaru cząstki oraz podłoża. Porównano otrzymane wyniki analizy dla cząstek padających na podłoże z prędkością 500 oraz 800 m/s.
Abstract
The paper presents the results of stress and temperature distributions during thermal spraying of Ti particle onto Al2O3 and Armco substrate. The finite element model of dynamic impingement of Ti particle has been built and the displacement and penetration of the particle into the substrate material analyzed. The time dependent variation of stress and temperature were analyzed in points selected from the particle and substrate regions. The calculations have been performed for the two differ- ent particle speeds equaled 500 and 800 m/s. The results comparison analysis have been discussed.
