Test specimen for detecting abrasive wear on surface in particle-laden gas or liquid flow, has shape of profile having elongated arcuate cross section, where inner surface is formed concave and opposite outer surface is convexly curved

摘要

The test specimen has a shape of a profile (1) having an elongated arcuate cross section, where an inner surface is formed concave and an opposite outer surface is convexly curved. The two curved surfaces are arranged parallel to each other, where a radius of the inner surface is smaller than the radius of the outer surface by a thickness. A rotational axis (8) is provided, which passes through the center of the profile cross-section, where a circular disk (9) is formed on both ends of the profile for storage, and particularly for rotational adjustment.
