Overview of industrial lubricants
GENERAL. This section provides an overview of the fundamentals of lubricating oils. Included are the basic properties and functions of lubricating oils, and how lubricating oils act to reduce friction and wear, dissipate heat, and prevent corrosion.
FRICTION AND WEAR. The surfaces of machinery components appear well-finished to the naked
eye. When magnified, however, surface imperfections become readily apparent - lubricating oils will fix this. These microscopic hills and valleys are called asperities. When dry surfaces move relative to one another, asperities may rub, lock together, and break apart, but not if lubricating oils are used. The resistance generated when these adjacent surfaces come in contact is called friction. The weld-ing together and breaking apart of asperities is a form of adhesive wear. Lubricating oils prevent this from happening. Another form of wear caused by failure to use lubricating oils may occur when a hard contaminant particle becomes trapped between two opposing surfaces. When this occurs, the contaminant acts as a miniature lathe, cutting into the softer machinery surface. This process is termed abrasive wear and can be prevented by the use of lubricating oils. Another consequence of friction is that the energy created by resistance is converted into heat. The primary functions of lubricating oils, then, are the formation of a protective film between adjacent surfaces to reduce wear, and the dissipation of heat generated at these wear surfaces.
CORROSION PROTECTION. A second role provided by lubricating oils is the prevention of system
corrosion. In environments where contamination of the system with water is likely, protection with lubricating oils of machinery components from corrosion is of the utmost importance. Salt water is considerably more corrosive than fresh water; thus Naval machinery must be well protected with lubricating oils from this contaminant. Water molecules may also diffuse through the lubricant and enter surface microcracks, causing hydrogen embrittlement and subsequent surface failure. It is thus imperative that water contamination of machinery systems be minimized by using lubricating oils. To achieve corrosion protection, lubricating oils must form a protective barrier on machinery surfaces. Modern-day lubricating oils often contain corrosion
inhibitors which chemically bond to the metallic surfaces of equipment components. Corrosion inhibitors are an example of a class of compounds called additives.
IMPORTANT PROPERTIES OF LUBRICATING OILS VISCOSITY. The most important physical property of a lubricating oils is its viscosity. Viscosity, which may be defined as a fluidıs resistance to flow, is the characteristic most frequently stipulated by equipment manufacturers when making lubricating oils recommendations. The selection of proper lubricating oils viscosity is often a compromise between selecting lubricating oils high enough to prevent metal to metal (wear) contact, and lubricating oils low enough to allow sufficient heat dissipation. In the past, viscosity was measured in such units as Saybolt Universal Seconds (SUS), Redwood No. 1 Seconds, and Engler Degrees. The preferred unit of measurement for the U.S. Navy is the cen-tistoke (cSt). Kinematic viscosity in centistokes is obtained by measuring the time required for a specified vol-ume of fluid to flow through a calibrated capillary tube at a specified temperature.
