The Un Destructive Examination by Active Pulse Thermography of the Layers Deposited by Thermal Spraying

Abstract:

In this paper we propose to use active pulse thermography for detecting the defects from the layers deposed by thermal metal spraying, at the interface based on material-deposited material and from the and in the immediate vicinity. The method is based on stimulating a thermal spray metallic samples using two separate flasuri separated by a period of time. This method has been tested by several tests with defects obtained artificial. In this paper work the method it is presented with the theoretic base and the experimental results.
