Wire arc spray system using composite wire for porous coating, and related method

摘要

A wire arc spray system (100) use at least one first wire (102) and second wire (104) that include a composite wire (160) including a first material (162)1 at a core region thereof and a cladding including a second material (164)1 surrounding the core region. A controller (150) controls operation to propel heated material (120) created by the arcing of the first wire (102) and the second wire (104) at the arc point (114) to a surface (122) to be coated. A wire arc spray methodology for creating a porous metal coating (124) with all-metal wires (202, 204) is also provided.
