Research Regarding the Ultrasonic Examination by Thermal Metalspraying Deposits on OL50 Parts

Thermal Metalspraying is one of the most important reconditioning methods used nowadays throughout the world. One of the most acute problems regarding thermal metalspraying is the achievement of a proper adherence between the deposed layer and the base material. Testing this adherence is made in most cases by destructive control performed on test probes. However, in the case of final products reconditioned through metalspraying, the use of of non-destructive techniques is required. This paper presents a research made to establish the opportunity of using the ultrasonic control regarding the adherence of the materials deposed on the base material through thermal melaspraying.
