In addition to the roughening of substrate and component surfaces for thermal spraying by means of blasting, chip-producing processes are also being utilised for surface activation to an increasing extent. One well-known example of this is the use of cutting inserts for the incorporation of a dovetail profile into aluminium cylinder raceways for the positive-locking bonding of thermally sprayed wear protection coatings. In this specialist article, it is shown that the process combination consisting of knurling milling and deep rolling constitutes an efficient method of producing surface structures which permits the positivelocking substrate bonding of thermally sprayed coatings.
