Transformable multi-sample apparatus for dry erosion testing of materials up to 1000 C in the presence of corrosive gases

摘要

The invention relates to transformable multi-sample apparatus for dry erosion testing of solid materials intended for erosive and/or corrosive applications in the presence of corrosive gases in the temperature range from -100 °C to 1000 °C. In this invention, a centrifugal testing apparatus is developed to provide low consumption of corrosive gas or vapour, to reduce the number and complexity of apparatus elements affected by aggressive conditions to reduce cost of testing. The apparatus provides control of the erodent particles speed, angle and feeding rate, gas or vapour environment and independent adjustment of the samples, gas or vapour, and erodent particles temperatures. The erosion test is conducted in a sample chamber where the bulk or coated samples having tube or cuboid shape equipped with heaters or coolers are installed. The apparatus enables the cooling of the centrifugal erodent particles accelerator disk, i.e. rotor.
