Wet Chemical

The well known wet chemical treatments of the silicon surface and its native oxidation in air cause a high density of interface states, which predominantly originate from dangling bonds strained bonds or from bonds, between adsorbates and silicon surface atoms. Therefore, a number of wet-chemical treatments have been developed for ultraclean processing in order to produce chemically and electronically passivated surfaces [1]. The saturation of dangling bonds by hydrogen removes the surface states and replaces them by adsorbate-induced states, which influence the surface band-bending [2]. The first thermal hydrogen desorption peak from a hydrogen passivated Si surface in vacuum or inert gas ambient can be detected at around 380°C [3,4]. Simultaneously the combination of the hydrogen atoms of neighboring dihydrides generates a pair of dangling bonds. At around 480-500°C dangling bonds are generated on the silicon surface by desorption of the remaining hydrogen [5]. At that moment the silicon surface becomes extremely reactive.

Effect Of Surface

Lead-bismuth eutectic (LBE) is of interest as a coolant in the design of fast reactors and also as both a coolant and a spallation target in proposed transmutation schemes for radioactive waste. However, liquid metal corrosion to the structural materials can proceed via various processes: species dissolution, formation of the inter-metallic compounds at the steels/liquid metal interface... It is known that the formation of an oxide scale on a steel surface can protect it dissolution attack by liquid LBE. The variables that play an important role on the feasibility of the formation of an oxide layer and on its protective characteristics for steels in contact with LBE are oxygen content, temperature, materials composition and evolution with time, but also surface state of steels prior to testing or weld joints, being these parameters not very widely studied. For the study of the influence of the surface finishing, specimens with different surface states were prepared (as-received, grinded, grinded and polished and electrolitically polished). These treatments gave to the materials a different degree of cold working, the higher for the mechanised samples and the lowest for the electrolitically polished. Tests were carried out at 500 and 550°C from 100 to 2000 hours with two different H2/H2O ratios: 3 and 0.03. The general conclusion is that the effect of surface finishing on the corrosion/protection processes is not significant for the conditions tested.
