چکیده مقاله
Additive manufacturing technology is a modern manufacturing method of manufacturingmechanical parts that has many advantages for the production of small and large parts Inthis article, ultrasound surface waves were used to evaluate the quality of direct energydeposition DED processed Stellite 21 coatings on Inconel 718 under different preheatand deposition laser powers The surface wave speed and diffuse backscatter amplitudeof the ultrasound waves were correlated with both cracking and warpage of the coating Three different frequencies were used to excite surface waves because each frequencyhas a different penetration depth Considering destructive metallurgical characterizationas a reference, surface wave measurements were found to be effective for examiningcoating integrity
