Abstract
Objective To resolve the color difference problem of oxidizing films that often happens during hot alkaline chemical oxidation production of 60Si2Mn alloy steel. Methods The components and thickness of 60Si2Mn oxidizing films produced at differ-ent temperatures were analyzed by glow discharge spectrum GDS, and the surface morphology of oxidizing films was observed by SEM. The effect of alloy elements on chemical oxidation, and the effect of chemical oxidation temperature on the thickness, compo-sition and color of oxidizing films were analyzed on the basis of electrochemistry. Finally, process improvement measures were pro-posed for chemical oxidation of 60Si2Mn. Results The result showed that different chemical oxidation temperature had large effect on the contents of alloy elements and the thickness of 60Si2Mn oxidizing films. The different chemical oxidation temperature led to different thickness of chemical oxidizing films, while the difference in the contents of alloy components Si and Mn oxide led to color difference in 60Si2Mn oxidizing films. Conclusion As compared to ordinary steel, when the chemical oxidation temperature was (142±1) ℃, the thickness of oxidizing films and the stable content of Fe3O4 could be ensured, which further ensured the color consistency of 60Si2Mn oxidizing films.关键词
