It is show that the friction strengthening essentially increases the conveyors chain durability.
Thus, under friction without lubrication the wear-resistance of a pair of 40HN2MA and 40HN2MA
steel increases more than in 8 times after friction strengthening as compare with non-strengthening
one. Only one part of pair, more technological, was strengthened. Experimental industrial control
showed that the strengthened axes wear-resistance was less in more than 4 times and that of plates
more than 2 times as compared with parts of the industrial conveyors chain
