Forschung an der GSaME - Status und Ergebnisse 2012

In this work, concepts were developed for the planning of the robot trajectory for thermalspraying processes, which by controlling the parameters defined by the process kinematicsand the related phenomena, like the heat transfer to the substrate, lead to a better control ofthe coating properties. Two approaches of off-line programming were considered to give solutionto the problem exposed above. A model to minimize the temperature gradients withinthe substrate was developed considering the coating of planar substrates. The heat transferto the substrate during spraying was modelled and used for the optimisation of the spray pathin order to produce low temperature gradients in the composite, which led to reduced residualstresses in the coating. Furthermore, trajectory generation for coating of complex shapedcomponents was regarded as well. For that case, an increase in the degrees of free-dom ofthe handling system was carried out by implementing an external rotational axis, whichpositions the substrate during the deposition process and allows maintaining constantkinematic parameters in order to obtain homogeneous coatings. Numerical simulation of theheat transfer process during deposition was coupled to the robot programming tools and themodels were validated with experimental work.5.
