Abstract
The present invention relates to a device comprising a thermobalance equipped with a detector () for measuring acoustic signals emitted by a sample () hanging from the balance beam and a preamplifier () incorporated in the vicinity of the head of the balance. The invention allows gas phase kinetic study of the degradation of materials and of depositions on these materials under temperature (100 to 1400° C.). In particular, corrosion phenomena such as: oxidation, sulfurization, carbonizing, metal dusting, nitriding, hydridation, chlorination, molten salt attack, and combinations of these degradations. Besides, deposits on the materials can be due to coking phenomena (carbon deposits), deposition of molten salts, volatile compounds condensation. The invention allows evaluation of the efficiency of inhibitors against corrosion and deposition processes.
