| Abstract: | The constantly growing needs of the operational parameters of machines and engines, especially for aeronautical use, have brought about greater demands on lubricating oils. Various synthetic materials have been used since the Second World War,1 in increasing quantity, as substitutes for mineral based oil: esters from organic alcohols and mono- or dicarboxyl acids are among the most widespread. Quite a different type of synthetic oil is organosilicon compounds, known as ‘silicones’. This paper reports experimental data for a group of silicon compounds examined in comparison with other materials normally used as bases for synthetic lubricants. |
