Abstract
Hot corrosion studies were performed on pristine and abrasive water jet peened (AWJP) Ti–6Al–4V surfaces. Oxide scales form on the peened and pristine surfaces when coated with NaCl and exposed to 600 °C for 100 h. Despite similar oxide compositions on both surfaces, the thickness and roughness of the oxide scale on the AWJ peened surface is lower. The hot corrosion rate of the pristine surface is 2.5 times higher than that on the AWJ peened surface. Enhanced hot corrosion resistance of the latter is attributed to compressive residual stresses on the surface that retards diffusion of chloride in the material.
