Abstract
A test apparatus can test the erosion resistance of a specimen. The apparatus has an enclosure containing in its test chamber an abrasive medium. Also included is a spindle attached to the enclosure. The spindle has an inside end adapted to hold the specimen. A motor coupled to the spindle can spin the inside end at an adjustable angular speed within the medium. Preferably, a thermal jacket can moderate temperature within the spindle apparatus. The apparatus is used to spin the specimen through the abrasive medium at a chosen speed and then measure the extent of erosion.
