Publication number: 20100255336Abstract: A method and class of bond coat is provided herein that physically and chemically bonds solid layer lubricants and other functional coatings to a substrate by burnishing, for example, selected soft materials, including oxides such as antimony trioxide which is seen as a major improvement over conventional bonding or coating methods. The process is non-vacuum at ambient temperatures, no binders, adhesives, curing or baking. Lubricant performance can be enhanced by orders of magnitude compared to when the bond coat and burnishing process are not applied. The method is inexpensive, environmentally friendly, applicable to any substrate material, and scalable.Type: ApplicationFiled: March 31, 2009Publication date: October 7, 2010Inventor: Jeffrey S. Zabinski
