Popis: The effect of esters of phosphonic acids on frictional wear under diverse loads and sliding speeds has been investigated. The efficiency of such phosphonates as anti-wear additives depends on their structure and varies with the frictional modes. Principal groups of phosphonates have been grouped as esters which are ineffective under both high and low loads (esters with no chlorine atoms); esters which are effective under both high and low loads (CCl 3 -group containing esters), and esters which are effective under either high or low loads. The interaction of phosphonates with metal (steel) has been studied. Dissimilarity in the efficiency of esters as lubricating oil additives is explained by their different adsorption and chemical actions.
