The method of revealing and estimation of hardened and lossed of strength processes in galvanic de- posits on the basis of iron at wear process by their friction by sliding is submitted. Thus the contribution hardened and lossed of strength processes in values of resistance of wear process can be estimated on law of change of values of relative deviations row standing units of statistical set of values of resistance of wear process. It is established, that at wear process of alloys of galvanic iron deposits the contribution hardened and lossed of strength processes in resistance to deterioration depends on structure of an alloy and loading of test. At wear process of compositions on the basis of iron, with particles aluminium oxide and with concen- tration close to optimum structure, the contribution hardened and loss of strength processes is characterized by cyclicity and depends on loading in interface.
