	Effect of Nitric Acid Passivation on 316L Surface [Updated: 08/20/2005] [Filesize: 473K] Passivation has a profound effect on the chromium/iron ratio in mechanically polished Type 316L tubing. This publication summarizes the effect of nitric acid passivation time on the surface chemistry of polished sanitary tube.
	Color Tinted Electropolished Stainless Surfaces [Updated: 08/19/2005] [Filesize: 603K] X-ray photoelectron spectroscopy (XPS) was used to analyze the surface of electropolished stainless steel that exhibited different shades of blue, gold, and black. The near-surface Cr/Fe ratio was determined and related to corrosion resistance. The depth of the passive layer was measured for each of the colors.
	Stainless Steel Surface Analysis - Review [Updated: 08/19/2005] [Filesize: 40K] This publication is a review article, summarizing the use of Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) to analyze the surface of stainless steel. The results obtained on typical "industrially clean" stainless steel are discussed. The surface chemstry of 316L stainless steel as a function of nitric acid passivation time was measured.
