Abstract

The present paper describes a method to measure quantitatively the bonding between flattened particles in plasma-sprayed Al₂O₃ coating by utilizing the distribution of copper electroplated into the as-sprayed coating. As a result, it is clearly revealed that the mean bonding area is about 32% of the total apparent lamellar interface area. It can be considered that the limited bonding between flattened particles is controlled by the temperature of liquid droplets on impacting and limited time available for liquid droplets to wet formed coating surface.
