Abstract
The method of treating the surfaces of malleable light metal cylinder bores or other objects by blasting the surfaces with extremely high water jets for preparing such surfaces for subsequent coating with wear-resistant materials such as a thermal spray coating. The water not only cleans the surface but roughens it to produce a pitted surface with undercuts so that coating material fills the pits and undercuts to provide a smooth layer of coating material with a strong mechanical/adhesive bond.
