Abstract:

Particulate erosion rate as a function of temperature has been measured over the range from 20 to 900C. Surface materials were tungsten, tungsten carbide, and copper, with zirconium carbide and tungsten carbide abrasive powders. A laser Doppler velocimeter was used to measure particle velocity, which was dependent on gas temperature. Erosion rate was normalized by dividing by the square of the particle velocity. Experimental erosion data were correlated by an empirical relationship with the material hardness of the abrasive powder and surface material.
