Abstract

Corrosion in stainless steel cooling water piping in a nuclear waste processing facility occurred during an extended system lay-up. The failure characteristics indicated microbiologically influenced corrosion (MIC). The corrosion occurred at welds as pinhole penetrations in the surfaces, which opened into large subsurface void formations. Corrosive attack started in the heat-affected zones of the assembly welds, usually adjacent to fusion lines. Stepwise grinding, polishing, and etching in the affected areas revealed that voids generally grew in the wrought material as uniform, general corrosion. Tunneling (wormholing) erosion was also present. Selective attack occurred within the two-phase weld filler zone. The result was a void wall that was rough and porous-appearing, a consequence of preferential attack on the austenite. The three-dimensional spongy surface was studied optically and with the scanning electron microscope.

The effects of microstructural changes caused by welding on microbiologically influenced corrosion: Material and process implications

Book Walsh, D; Willis, E; Van Diepen, T

The microbiologically influenced corrosion (MIC) susceptibility of a material is inextricably linked to its microstructure. The thermomechanical cycle associated with welding produces extensive microstructural change in the vicinity of the weld. This work tested the hypothesis that fabrication procedure would alter MIC susceptibility. This study examined the effect of systematic variation in the amounts of cerium, sulfur and silicon on the corrosion susceptibility of welded AISI 8630 material in aqueous, anaerobic solutions. Samples were exposed to both sterile and biologically solutions. Biologically active solutions were invariably more aggressive. The changes in corrosion susceptibility were correlated to the changes in themore »« less
Susceptibility of stainless steel weldments to microbiologically influenced corrosion

Conference Borenstein, S

Microbiologically influenced corrosion (MIC) is the term used for the phenomenon where corrosion is initiated or accelerated by microorganisms. Biofilms of bacteria form on metal surfaces when exposed to natural waters. The activity of these biofilms and how they attach themselves to metal surfaces directly influence corrosion mechanisms. This paper describes the mechanisms for MIC and the factors which influence the susceptibility of austenitic stainless steel weldments to MIC. The metallurgical, microbiological and electrochemical factors that influence MIC are discussed. Case histories of MIC-related failures and field test results of austenitic stainless steel weldments in various welded conditions are presented.
Role of surface finishing on pitting corrosion of a duplex stainless steel in seawater

Journal Article Salah-Rousset, N; Chaouachi, M; Chellouf, A - Journal of Materials Engineering and Performance

Localized corrosion of duplex UNS S32550 stainless steel in seawater was investigated in the laboratory and in field trials for several surface finish conditions: polished, ground, and sandblasted. Electrochemical data obtained by polarization curves showed that the smoother, polished surface had better characteristics (higher pitting and protection potentials) than the ground or sandblasted surfaces. However, despite its high degree of roughness, the sandblasted surface was the most resistant in field conditions, exhibiting the lowest number of sites attacked. Internal compressive stresses created by sandblasting seem also to have an unsensitizing effect on sensitized zones that exist in cast steel (duemore »« less

Microbiologically influenced corrosion of stainless steel weld and base metal -- 4 year field test results

Book Felder, C; Stein, A

This paper presents the results obtained from a 4-year test program to determine the effects of microbiologically influenced corrosion (MIC) on piping materials under service conditions representative of a fresh water cooling water system. The test was performed in a field installed test loop and was constructed to operate under four typical flow conditions: continuous flow at 4--6 fps (1.2--1.8 m/s), continuous flow at 0.5--1 fps (0.15--0.3 m/s), intermittent flow, and stagnant. Test materials consisted of pipe spools as well as coupons fabricated from Type 304, Type 316, Type 316L, and 6-percent molybdenum stainless steel, and titanium pipe. The pipemore »« less
