This article presents one of the most advanced technologies for the application of powder coatings, the detonation spray method. The devices for measuring the temperature and the velocities of the powder particles are presented and the results obtained are shown. The article deals with results from wear tests as well as from fatigue strength tests. The tests are carried out on the coatings of the Ni-Cr-B-Si type applied to C45 steel. In addition, X-ray examinations, linear distribution of the chemical elements, microhardness measurements and metallographic examinations are carried out. The coating properties of the detonation-sprayed layers are compared with the same coatings, which were applied by means of plasma or flame spraying. Paper includes a German-language abstract.
