METHODS FOR SUB-AUSTENITE TRANSFORMATION TEMPERTURE DEPOSITION OF INORGANIC PARTICLES AND ARTICLES PRODUCED BY THE SAME

Abstract:

Methods of applying an inorganic material to a metal substrate that includes a metallic material having an austenite transformation temperature. The method includes depositing inorganic particles onto a surface of the metal substrate. In some embodiments, methods may include depositing inorganic particles at a deposition temperature that does not cause the metallic material to exceed the austenite transformation temperature. The inorganic particles deposited onto the surface of the metal substrate may form an abrasion-resistant coating on the surface of the metal substrate. The difference between the coefficient of thermal expansion of the metallic material and the coefficient of thermal expansion of the abrasion-resistant coating may be 10.times.10.sup.-6/degrees C. or less.
