EXPERIMENTAL STUDIES ON HIGH-TEMPERATURE CORROSION INTERACTION OF TIN-LITHIUM ALLOY WITH STAINLESS STEEL AND REFRACTORY METALS

This article describes experimental investigations to determine the corrosion compatibility of candidate matrix materials a capillary-porous structure (CPS) with liquid tin-lithium alloy at high temperatures. The studies were conducted Sn 75 -Li 25 and samples 12Ch18Ni10Ti grade austenite stainless steel, VEL-3 vanadium, TT tantalum. Experiments on interaction CPS temperatures carried out an TiGrA setup based TGA/DSC 3+ thermogravimetric analyzer. paper provides description methodology conditions for conducting high-temperature tests. In course this work, experiments study in phase vanadium tantalum temperature range from 600 ℃ 1000 ℃. Based obtained results, thermal effects processes occurring as result determined. As analysis results it has been revealed that studied complex physical chemical take place, such as: selective dissolution components by (solvent); penetration component (tin) into steel depth; mass transfer dissolved metals solid metal liquid.
