CHARACTERISATION OF METALLIC LAYERS DEPOSITED THROUGH THERMAL SPRAYING

The characterization of the metallic layers deposited through thermal spraying can be done with different destructive and nondestructive techniques. In this article the authors describe ultrasound immersion. The purpose of the paper is to characterize the quality of thermal spray deposited layer adhesion to the base material. The parameters of the technological process of deposition through thermal metal spraying which have been taken into consideration to establish the quality of adhesion are deposited material granulation, deposition pressure, nozzle diameter of the torch used for deposition, spraying distance, and deposition angle. A series of tests to determine the influence of changes of certain parameters of technological process deposition thermal metal spraying on the quality of adhesion were performed.
