Abstract <p>The research of the pulsed magnetic field effect on the surface microhardness and residual microstresses of the samples made of titanium alloy VT-6 with ZrN, ZrNbN coatings are conducted. It is established that the mode with an energy of 10 kJ and a number of pulses equal to four are the most effective to change surface properties when magnetic-pulse effect with the use of high-frequency installation MPU-3 on researched samples is carried out. It is shown that the magnetic-pulse treatment of samples with ZrN coating leads to microhardness increase by 8–11% and up to 20% for samples with ZrNbN coating. When studying the pulsed magnetic field effect on residual stress, it is established that the treatment of studied samples with ZrN, ZrNbN coatings is followed by the compressive residual stresses. The treatment of studied samples under MPU 20–21 installation, where an increased exposure duration has been used, enables reducing the coefficient of microhardness values as well as to regulate residual microstresses on the surface and approximate them to zero.</p>
