The object of this paper is to study the effects of lubricant film flow, pressurized and sheared between two parallel rough surfaces in sliding motion. The influence of microscopic surface roughness on lubricant film flow macroscopic behavior is described through five nondimensional parameters called flow factors. These macroscopic transport parameters are related to the local geometry of apert...
The products based on fossil oils are increasing with the concerns of environmental sectors and academics as well. In this era, there challenges to finding alternative resources replacing oil for different engineering applications. One is lubricant. Fossil lubricants have many industrial applications involve millions dollars each year in development due their huge needs. Accordingly satisfy nee...
Lubricant selection and cleaner chemistry is oftentimes one of the most overlooked parts of industrial metal processing. Their selection can affect not only the ability to adequately clean parts; it can also potentially affect the success of a waste minimization effort to recycle the cleaner. Certain lubricants are more compatible with certain cleaning processes than others. This paper will dis...
The present concept of being globally “green” puts additional demands on lubricants. They are to be biodegradable and ecofriendly. Therefore, in a search for alternate lubricants meeting the above demands, we have synthesized biodegradable new generation esters using alcohols such as 2,2-dimethyl-1,3-propane diol and 2,2-diethyl-1,3-propane diol and fatty acids like caproic and 2-ethyl caproic ...
It can be said that lubricants are used to reduce the friction between rubbing surfaces. This is done by separating the moving surfaces with a film of the lubricant, thereby replacing the friction of the metal to metal surfaces by the internal friction within the lubricant itself. Lubricants also act as a cooling agent to carry away heat generated by friction or conducted to the bearing surface...
