Study on the Relationship of Hydrogen Content and Ultrasonic Propagation Properties

Abstract:

Hydrogen-induced corrosion is a common damage in petrochemical industry. It can rise crack and bubbling on the surface of metal materials when the hydrogen corrosion is in the stage of severity. In the present, it is hard to evaluate the material conditions nondestructively under hydrogen attack. In this paper, the possibility of the relationship between ultrasonic propagation properties and the content of hydrogen corrosion was investigated. We have found that the surface wave velocity is a parameter, which can be directly correlated with the hydrogen content. The sensitivity has been found to be acceptable.
