Copper and copper-tungsten composite coatings were produced by high velocity oxy-fuel spraying. After initial optimization of the spraying parameters, coatings of various compositions were made and their structure, composition, mechanical, thermal and electrical properties were characterized. The HVOF technique was able to produce rather dense coatings with minimal oxide content and relatively good mechanical and thermal properties compared, for example, to plasma sprayed coatings, however, the achieved tungsten content was quite low.

Nástřiky na bázi mědi a wolframu byly vytvořeny technologií HVOF a byla provedena charakterizace jejich struktury, mechanických, tepelných a elektrických vlastností. Metoda HVOF poskytuje velmi kompaktní nástřiky s řadou pozitivních vlastností, ale nízkým obsahem wolframu.
