摘要：

The effect of formic acid (HCOOH) in simulated boiler water containing chloride ions (Cl-) on the corrosion behavior of STBA24 lowalloyed steel and its weldment was investigated using electrochemical corrosion tests, immersion corrosion tests and surface analyses. The addition of 100 ppm HCOOH into water containing 100 ppm Cl- resulted in thicker films with poor corrosion resistance that were formed easily on both the base metal and the weldment of STBA24, even though pit initiation was inhibited within a short time. The results suggest that the presence of 100 ppm formic acid in the simulated boiler water containing 100 ppm chloride ions promotes corrosion of the materials tested.
