Abstract
A sintered spray powder includes from 5 to 50 wt.-% of a metallic matrix, from 50 to 95 wt.-% of a hard material, and from 0 to 10 wt.-% of a wear-modifying oxide, each based on the total weight of the sintered spray powder. The metallic matrix comprises from 0 to 20 wt.-% of molybdenum based on the total weight of the metallic matrix. The hard material comprises at least 70 wt.-% of molybdenum carbide based on the total weight of the hard material. An average particle diameter of the molybdenum carbide in the sintered spray powder is <10 μm, determined in accordance with ASTM E112.
