Technology
Laser assisted plasma spraying is a combination of atmospheric plasma
spraying and laser cladding. This process combination enables significantly
higher deposition and feed rates. The cost effectiveness of laser cladding
is limited by the low deposition rate, which does not exceed 1 kg/h for
process typical feed rates of 400 … 1000 mm/min. With plasma spraying,
a 10 times higher deposition rate can be achieved, but application areas
are limited by poor adhesion and the characteristic layer porosity.
The newly developed hybrid technique of laser assisted plasma spraying
is a one-step process where the coating gets sprayed and simultaneously
molten to the substrate. The spray rates of up to 12 m/min are clearly
higher than the feed rates of laser cladding. The integration of a plasma
torch and a Nd:YAG laser treatment head into a modular deposition unit
offer versatile applications.
