Preparation of Water-Resistant Electrode Coating with Palmitic Acid by Microwave Reaction

Abstract:

Article Preview

Absorbing moisture of electrode coating easily leads to high diffusible hydrogen of welding seam, resulting in hydrogen embrittlement, porosity, cold crack and other defects.Microwave absorption material Fe3O4 is used to promote the reaction of palmitic acid, and reduce the diffusible hydrogen of weld bead. Electrode is immersed to the light petroleum solution containing palmitic and Fe3O4 particles, then the electrode is put into the microwave oven and become water-resistant . The results of FT-IR and SEM indicate that Fe3O4 absorb the microwave and lead to the reaction of palmitic acid and electrode surface. The electrode become water-resistant after microwave reaction, The best ratio of palmitic acid in the petroleum ether is 15%, and the weld diffusible hydrogen decreases to 74%.
