Aqueous slurry erosion in some cobalt base superalloys
Description
An orifice erosion test was usd to study the influence of metallurgical variables in a series of cobalt base superalloys on their resistance to erosion by aqueous slurries of SiO2. A slurry of 30 pct solids by weight of 4.5 μm silica was used to erode a variety of microstructures obtained by compositional and processing control. The time dependence of the pressure drop across an orifice (P) was found to follow the relation P = Kt/sup -n/, where t is time (min), and K and n are constants. The erosion exponent, n, varied from 0.052 to 0.148 and was found to be dependent upon carbon content and processing variables
