The gases represent the anode side, start-up/shut-in and the cathode side, respectively. Differences between the two materials and their response at the different...

... on surfaces. CaCO3 surface scaling kinetics was investigated by evaluating the induction times and gravimetric measurements of mass gain in the capillary cell. Scale precipitation tests were carried out on as-received (plain) and functionalized stainless steel substrates at three saturation ratios and flow...

... Abstract To obtain heat affected zone (HAZ) hardness levels below maximums specified in the current (2015) edition of NACE (1) MR0175/ISO (2) 15156-3 for sour service use, welded super martensitic stainless steels (SMSS) need post weld heat treatment (PWHT). PWHT is mainly done by stress...

... reducing the service life of these alloys. The objective of this study was to determine whether the surface roughness of an alloy has a significant effect on its corrosion resistance in the presence of microorganisms.

... of the fuel cell. One approach to overcome these issues is the use of metallic substrates. However, potential candidates for this application must be both corrosion resistant and electrically conductive. In this study, the surface of stainless steels was modified to achieve enhanced corrosion resistance while...

... ABSTRACT In this work, the peridynamic corrosion model is used for 3D simulation of pitting corrosion in stainless steel. Models for passivation and salt layer formation are employed to predict detailed characteristics of pit growth kinetic in stainless steels, such as lacy cover formation...
