Abstract
A composite flame spray powder comprising powder particles having as components, cast iron, molybdenum (as such and/or as ferromolybdenum), and boron (as such and/or as ferroboron), unalloyed together. The composite particles are preferably in a form having a cast iron core, of a size between -170 mesh standard screen size and +15 microns, with particles of molybdenum and boron of a size between about -20 and +0.1 microns, bound to the surface of the cast iron core with a binder, the molybdenum being present in amounts of about 20% by weight and the boron in amounts of about 1% by weight based on the total of the cast iron and molybdenum. When flame sprayed, the composite particles produce a coating having high wear and scuff resistance characteristics and low friction.
