Subject : 620.1 Material Science and Technology
Keywords : Stress corrosion cracking ;Cavitation;Dealloying;Bimetallic corrosion;Pitting
Abstract : This paper gives a brief description of typical marine environments and the most common form of corrosion of materials used in this environment. Some typical case histories of failures pertaining to pitting, bimetallic corrosion, dealloying, cavitation and stress corrosion cracking are illustrated as typical examples of corrosion failures. |

Keywords : Reynolds equation;Velocity-slip;Viscosity;Roller bearings;Cavitation;Load capacity ;Coefficient of friction
Abstract : A generalised form of Reynolds equation for two symmetrical surfaces is derived considering velocity-slip at the bearing surfaces. This equation is applied to study the effects of velocity-slip for the lubrication of roller bearings under lightly loaded conditions. Expressions for the point of cavitation, load capacities, and coefficient of friction obtained are also studied theoretically for various parameters. |
