ABSTRACT:
A method of forming a high-temperature abrasion-resistant hard facing or coating on a ferrous metal substrate by employing an aluminothermic reduction reaction. The resultant article has a hard facing layer containing from 2 to 8 percent boron. Hard faced composite articles made by the invented method, such as sintering machine crash decks, coke pusher ram shoes and grizzly bars are also disclosed.
