【 摘 要 】

The paper proposes a simulation model made using the method of finite element analysis for the case of thermic transfer by infrared thermographic control with impulses for specific sample parts with induced defects. Results showed a correlation between the finite element analysis and the images obtained by infrared thermography with a maximal error of 5-6%. This correlation proves the viability of the model and could represent the basis for the developing of a working instrument for non-destructive testing of parts that are conditioned or reconditioned by thermal spraying technology.
