Method and apparatus for thermal spraying cylindrical bores

摘要

Disclosed are a method and apparatus for coating the interior surface of a cylinder wherein a consumable electrode is fed to an arc formed between a rotating non-consumable electrode and directing an atomizing gas through the arc formed to carry the molten metal of the consumable electrode to the cylinder wall to coat the wall and wherein the consumable electrode is introduced into the cylinder from an end opposite the rotating non-consumable electrode.
