Abstract
Abstract A flame spray material comprising particles having a nickel, copper or iron core coated with aluminum and molybdenum. Advantageously, based on the weight of nickel, copper, iron, aluminum and molybdenum the nickel, copper or iron is present in about 66 to 97.5 percent, the aluminum in about 2 to 18 percent and the molybdenum in about 0.5 to 16 percent. The material produces a selfbonded wear resistant coating which can readily be machined.
