Process for the fluid blasting of cylinder bearing surfaces which are subsequently to be thermally coated

摘要

In a process for fluid blasting cylinder bearing surfaces which are subsequently to be thermally coated, a cylinder crankcase is cast, those surfaces of the subsequent cylinder barrels which are to be thermally coated are roughened, the cylinder barrels are coated by a thermal spraying process, and the cylinder barrels are remachined to their final dimensions. The surfaces of at least two cylinder bores are roughened simultaneously by one jet for each cylinder bore.
