Properties of the SIBOR oxidation protective coating on refractory metal alloys

Popis výsledku v původním jazyce

The SIBOR (Si-10B-2C) oxidation protective coating was applied onto molybdenum-, molybdenum-3 vol.% ZrO2 (zirconia)- and tungsten-samples by APS (= atmospheric plasma spraying) with a subsequent heat treatment. The coated samples were submitted to ramp oxidation tests with heating rates of 10 °C/h up to a temperature of 1450 °C with a subsequent dwell time of 24 h. This procedure simulates the heating up of a glass melting tank where SIBOR coated parts are most frequently used. Some of the as coated samples and samples which were oxidized without any defect were immersed in various molten glasses to determine the dissolution behaviour of the SIBOR substrate system. This simulates the situation when the glass melting tank is filled and operated with molten glass. SIBOR proved to be an excellent oxidation protective coating for the molybdenum-zirconia-material and for TZM like for pure molybdenum, but not for tungsten, most probably because of the different thermal properties of the refr
