Machining and Characterization of Functional Surfaces of Thermal-Coated Cylinder Bores

Machining of thermal-sprayed layers is a new challenge for machining cylinder bores with different honing variants. New strategies for machine and tool layouts as well as in particular the availability of appropriate diamond stones considering the material-specific properties of the cutting process are essential. Based on the coating material characteristics which are relevant for machining, a new honing process is presented.Following the material properties of thermal-sprayed layers, the machining task, the process layout and the obtained quality values are described. Also the different variants of machining strategies are indicated, which are applicable for the different thermal-sprayed layers. The paper describes the machining results regarding the functional properties.
