Optimized multiaxis robot kinematic for HVOF spray coatings on complex shaped substrates

High accuracy robot systems are required for an efficient and reproducible application of thermal spray processes. Due to the influence of the torch trajectory on the heat and mass transfer processes during the deposition of APS and HVOF coatings, specific software tools for the simulation, generation and implementation of these trajectories must be developed. The internal HVOF series coating process of cylinder bores in lightweight engine manufacturing, the series production of optimized oxide ceramic coatings on textile surfaces and the trajectory generation and simulation for the coating of a complex 3D surface will be presented as case studies of these technologies.
