The paper presents the effect of an increase in wear resistance after several operating cycles of
hard-alloy plates is investigated and the results of investigations. The plate is heated to one-third of the melting temperature and subjected to air fluctuations with frequencies of 160–800 Hz. A hypothesis on how aerodynamic impacts occur on hard alloy surfaces is presented. An experimental way to strengthen the surface layer of metal cutting plates is described. It is revealed that under industrial condition the mean time between failures for the plates processed by mentioned procedure is 1.8–2.2 times higher than for the standard delivery plates.
