<p>In a method for depositing wear-resistant dispersion coatings consisting of matrix metal and hard-material particles on metallic components by means of plasma spraying as illustrated in Fig 1, the hard-material particles (11) are sprayed separately from the plasma stream of matrix metal (10) into the plastically still deformable matrix metal (6). The matrix metal and the hard-material particles may be deposited synchronously or step by step in succession. Coatings (1) of this description are deposited in evacuated chambers or under inert gas on the blade tips of gas turbine engines. on the sealing fins of labyrinth seals or as rub coatings (1) on circumferential surfaces (4) of, e.g. rotors (2). <IMAGE></p> |
