Effect of elastic stress on anodic dissolution behavior of TA2
Source abstract
Abstract
The anodic dissolution behaviors of TA2 under elastic stress in acidic 3.5 % NaCl solution with or without 5 mM NaF were investigated using in-situ scanning electrochemical microscopy (SECM), along with polarization curve, SEM and AFM. The results indicated that the dissolution of the passive film in 3.5 % NaCl solution was accelerated under 100 MPa, and more resistant to dissolve under 200 MPa. In presence of 5 mM NaF, the stress intensified the dissolution of the matrix. Specifically, 100 MPa stress increased the corrosion difference between different grains, while 200 MPa stress made the corrosion of TA2 more uniform.
