Product change for nozzle improvement

New nickel-plated A250, A350 and A450 nozzles

The surface of the A250, A350 and A450 nozzles used in conjunction with the plasmabrush® PB3 will be nickel-plated in the future. This will prevent the formation of a loosely attached copper oxide layer. Our investigations showed no change in the process parameters current, voltage, power, plasma and nozzle temperature, activation area and service life due to the nickel plating.

Comparison of new and old nozzles
Fig. 1. Comparison of the new nickel-plated copper nozzles (see above) and the old copper nozzles (see below). Left: nozzle A250, middle: nozzle A350, right: nozzle A450.

The example of nozzle A250 shows that the surface of the nickel-plated nozzles is intact even after a duration of more than 390 hours (see below). This prevents contamination of the samples by oxide residues.
