Download or read book Friction, Wear, and Surface Damage of Metals as Affected by Solid Surface Films written by Edmond E. Bisson and published by . This book was released on 1955 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: As predicted by friction theory, experiments showed that friction and surface damage of metals can be reduced by solid surface films. The ability of materials to form surface films that prevent welding was a very important factor in wear studies of dry and boundary lubricated surfaces. Films of graphitic carbon on cast irons, NiO on nickel alloys, and FeO and Fe3O4 on ferrous materials were found to be beneficial. Abrasive films such as Fe2O3 on MoO3 were definitely detrimental. It appears that the importance of oxide films to friction and wear processes has not been fully appreciated.
