Description

This talk will look at cost effective and environmentally friendly surface treatments to improve the corrosion resistance of SS 316. Mechanically polished samples were treated by heating in deionized water, a hydrogen peroxide solution, electropolishing and heat treating in an oven. Cyclic voltammetry and optical microscopy were used to measure corrosion on the samples in a 0.9% NaCl solution. X-ray photoelectron spectroscopy was also used to analyze the composition of the different oxide layers. The greatest improvement in corrosion resistance was observed after treating the steel in a hydrogen peroxide solution. However, electropolishing also showed a large improvement while having other practical advantages.
