Twin wire arc spray coating method for component e.g. cylinder bore of internal combustion engine, involves detecting and supplying process variables influencing coating process to process controller that controls variables

摘要

The method involves making multiple wires from a coating material. The electrical power is supplied to an arc, by the wires. Multiple process variables influencing a coating process are detected, and supplied to a process controller. The process variables are controlled by the process controller, based on a process model. The wires are heated and softened before performing an arc atomization by current flow. An independent claim is included for a twin wire arc spray coating apparatus.
