New Approaches in the Hypersonic Flame Spray Coating for Cylinder Liners in Aluminum Crankcases

Optimized robot trajectory generation for thermal spraying operations and high quality coatings on free-form surfaces

“…When the substrate and coating temperatures are compensated, the composite cools down to room temperature. During this process, the mismatch in CTE between the coating and substrate leads to the formation of thermal stresses [12,13]. The thermal load on the composite can be varied with the torch relative speed during coating.…”

“…Residual stresses in the coating system are generated during the production process due to the macroscopic and microscopic nonhomogeneous elastic and elastic-plastic deformation after mechanical and/or thermal load [12,13]. During coating deposition, splats cool down and solidify transferring heat to the substrate and environment.…”
