Abstract

A molybdenum-based composite powder for thermal spray applications. The composite powder includes a molybdenum-chromium, molybdenum-tungsten, or molybdenum-tungsten-chromium alloy dispersion strengthened with molybdenum carbide (Mo.sub.2 C). The molybdenum-based composite powder may be combined with a nickel-based or cobalt-based alloy to form a two-phase powder blend. The coatings from such powders are made up of molybdenum-based alloy lamellae and, in the two-phase embodiments, nickel-based or cobalt-based alloy lamellae. The coatings exhibit improved corrosion resistance and strength while retaining good sprayability.
