Cylinder barrels thermal coating method involves moving plasma spraying gun (1, 2) having plasma spraying head(s) (3, 4) into interior of cylinder bore of cylinder barrel (8) to be coated. A flow of air with flow velocity of 7-12 m/s, is then created via cylinder bore (7) of barrel, and coating material is sprayed onto cylinder barrel. The flow of air is maintained during entire coating operation. An Independent claim is also included for an apparatus for thermally coating the cylinder barrels of a cylinder block of a combustion engine. |
