Abstract
A novel methodology is proposed for corrosion-wear measurement in the Heat affected zone (HAZ) of 11%-Cr ferritic stainless steel. Weld beads with different stress-concentration were manufactured by using MIG/MAG process. After, the welded sample is extracted from the plate, the beads were bended and external stress was applied. Finally, they were inserted in ferric-chloride solution. Corrosive wear were assessed by means of optical microscopy in the HAZ by using polymeric resin mask and comparing profiles before and after inserting the sample into the solution. The results demonstrate the feasibility of the proposed methodology for assessing corrosive wear in the HAZ.
