The work is devoted to the study of processes occurring in the boundary lubricant layer. in which nanodisperse magnetic particles play a decisive or significant role. The friction between metal surfaces with lubricated oils of different concentrations of the magnetic nanodisperse phase was studied. The dispersion medium of magnetic oils consisted of liquids with various physico-chemic... https://www.chiggate.com/3m-speedglas-9002nc-welding-helmet-fashion/
