Lochyński P., Chlebus E., Łyczkowska E.,

316L stainless steel was electropolished in 3 electrolytes consisting of H2SO4, H3PO4 and org. additives (Et3N, OHCH2CH2OH, (COOH)2, PhNHAc, glycerol) at 55°C and anodic current d. 20 A/dm2. In the Et3N-contg. bath, the roughness Ra was 0.063-0.065 [mikro]m and in the OHCH2CH2OH, (COOH)2 and PhNHAc-contg. bath, 0.091-0.096 [mikro]m. The bath consisting H3PO4 and glycerol (50% by vol.) was efficient only at above 90°C (Ra 0.070 [mikro]m).

Project assumptions

The overall goal of the project is to develop an innovative multifactor mathematical model enabling monitoring of bath contamination used in the electropolishing process of austenitic stainless steels. This model will allow optimization and reduction of process costs and will have an impact on reducing environmental pollution during electrolytic polishing of austenitic stainless steels.

The final outcome of the project will consist in the development of a method of monitoring the gradual contamination of the electropolishing bath.
