Wire spraying apparatus

摘要

An apparatus for producing coatings to protect against wear and corrosion by thermal spraying using a nozzle and wires which are processed at a distance from a wire spraying system has a nozzle system about the nozzle which atomises a molten metal drop for injecting hard-material particles and hard-phase particles into the spray jet without melting-on or remelting and the wire is provided so as to be drivable. In addition, the wire is to be assigned a wire driving unit at distances of 2 to 10 m from the wire spraying system, said unit driving the wire and operating according to the push-pull principle.
