Oxidation of Thermal Sprayed Metallic Materials during Flying in Air and the Coating Structures

Abstract:

Copper, iron and a nickel-chromium alloy were thermal sprayed onto a mild steel substrate in air and the structures of the sprayed particles that were collected during flying and those of the coatings are examined. The coatings consist of metal layers and metal oxide layers, and the minor phase layers become disintegrated and granulated on annealing. This morphology change is caused by the balance of the boundary energies.
