Abstract
Detonation sprayed coatings are nowadays applied on many kinds of heavily loaded sliding pairs and in the case high-speed machines. The basic problem in such applications lies in their durability and their scuffing resistance. Detonation sprayed coatings have a different in comparison with other junction surfaces microstructure and their behaviour in boundary condition let us better estimate possibilities of their application. This paper deals with the findings from experiments with regard to the seizure phenomenon when the friction pairing embodies an element with detonation-sprayed coatings. The progression of seizure is examined and evaluated for a number of aluminum oxide-13 titanium dioxide WC-Co 88/12 coatings that were applied to steel by means of detonation spraying. Paper includes a German-language abstract.
