...Ruiyu Li; Bing Bai; Lei Deng; Defu Che To study the corrosion characteristic of 20G steel in saline circumstances with sodium sulfate (Na 2 SO 4 ), a series of corrosion experiments are implemented on a novel setup. The corroded steel samples are analyzed by X-ray photoelectron spectroscopy and X...

... to find out the oxygen and carbon contents and the phases present in the alloys. Transformation temperatures determined by differential scanning calorimetry indicate that the addition of vanadium reduces the transformation temperatures. Corrosion studies were carried out in Hanks’ solution, while...

... nodules and the matrix in aggressive environments, these nodules can, at the same time, reduce its corrosion resistance. In this study, composite carbide coatings were grown on the surface of GGG-80 using the thermoreactive diffusion (TRD) process. The process was carried out at 900, 1000, and 1100 °C...

...Yuanyang Miao; Shengli Lv; T. S. Srivatsan; Xiaosheng Gao This study attempts to provide a theoretical estimate coupled with an analysis of the measured data to predict pitting damage of an aluminum alloy 2219 under the conjoint influence of mechanical load and corrosive environment. In accordance...

...Ali Günen In this study, the effect of different boriding parameters on some mechanical properties and corrosion resistance of AISI H11 steel, which is extensively used in hot and cold processing applications, was investigated. The grown boride layers were compact and crack-free for all boriding...

... on hardness, tensile strength, and corrosion rate was investigated. The Tafel extrapolation method was carried out to determine the corrosion rates of AA6061 and AA7075 base metals and AA6061–AA7075 joints. Increasing heat input was found to be detrimental for both mechanical properties and corrosion...

...F. Rumiche; J. E. Indacochea; M. L. Wang An electromagnetic sensor was assessed as a possible instrument for nondestructive detection and monitoring of corrosion in structural carbon steels. In this study, the magnetic response of three structural carbon steel rods (AISI 1018, AISI 1045, and AISI...

...Dong Yang; Preet M. Singh; Richard W. Neu Industrial boilers experience bulbous cracks in carbon steel water-wall tubes and other water-touched surfaces. Because these cracks are blunt and different from sharp fatigue cracks, they are generally referred to as stress-assisted corrosion (SAC) cracks...

... processes—aqueous corrosion is one such process. The complex microstructures in cermet coatings have been shown to translate to complex modes of corrosion attack. In this paper an electrochemical test methodology to probe the local/microaspects of corrosion initiation and propagation will be described...

.... The samples were degraded in the neutral 3.5% NaCl solution for a month ≑ 720 h at 23 ° C (room temperature corrosion, RC) and 100 ° C (high temperature corrosion, HC). It is noted from surface observation of the corrosively degraded samples that the RC-samples ( SiCp / Al and AA6061) were degraded by pitting...

...Michael V. Seica, Research Fellow; Jeffrey A. Packer, Professor The problem of deteriorating water pipes, resulting in leaks and breaks, affects municipalities worldwide. Corrosion appears to be a leading factor affecting pipe strength and service life. While techniques to evaluate the corrosion...

...Khosrow Zarrabi; Ian Rose Superheater and reheater tubes in a fossil-fuelled boiler are subjected to erosion and corrosion that cause the tubes to lose their thickness in a localized manner. To avoid unscheduled tube failures due to creep damage and hence prevent large financial loss because...

..., is currently being developed. The corrosion and temperature-strength properties of currently available metallic materials limit the maximum efficiency of this cycle. Recently, ceramic matrix composites have shown promise in overcoming the design limitations on future power plants. In particular, the high...
