Titanium and its alloys are used in several industries, especially in medical and dental applications. In the present study, the surface properties of nanostructured commercially pure titanium (CP-Ti) and its erosion–corrosion (E–C) behavior in simulated body fluid were studied. Equal-channel angular pressing (ECAP) was performed at a high temperature (400 °C) to produce nanostructured grain samples of CP-Ti. Then, the effects of ECAP passes on the E–C resistance under various conditions were investigated via weight loss measurements. Optical microscopy and transmission electron microscopy observations were performed to investigate the microstructural changes of the material. The surface roughness of the CP-Ti samples was evaluated using an optical profiling system. Mathematical equations of the modified Finnie model were employed for the analytical analysis of the E–C behavior. Additionally, computational fluid dynamics was utilized to model the E–C behavior of CP-Ti. Overall, the results showed that the ECAP process improved the E–C resistance of CP-Ti. A difference of 12 pct was observed between the experimental and numerical results of E–C resistance, which is acceptable for practical applications
