摘要：

For achieving the stress evaluation of plasma sprayed cladding layer based on metal magnetic memory testing technology, static tensile tests of plasma spraying specimen are carried out. Meanwhile, the magnetic signal is measured through the tensile tests. The normal component of magnetic signal, Hp(y), and its gradient K, the tangential component of magnetic signal, Hp(x), and its average value, Hp(x)avg, changing with tensile stress are investigated. The results indicate that the Hp(y) rotated anticlockwise and its gradient K increase exponentially, and Hp(x)avg increases linearly with the increase of stress in the elastic stage. While in the plastic stage, the K and Hp(x)avg decrease with the further increase of stress. The mechanism of stress evaluation of plasma sprayed cladding layer is discussed from viewpoint of the microstructure and magneto-mechanical effect. © 2016 Journal of Mechanical Engineering.
