Получены новые знания о влиянии циркония в составе ионно-плазменного покрытия (Ti, Zr)N, наносимого на сплав ВК10КС. Ионно-плазменное покрытие (Ti, Zr)N наносили на установке «Квант-6», используя раздельные катоды из титана и циркония из расчета 50 % Ti + 50 % Zr с применением азота в качестве реакционного газа. В этом случае два катода из титанового сплава расположены в камере установки друг против друга, а катод из циркониевого сплава – между ними. Установлено, что введение циркония в состав покрытия (Ti, Zr)N приводит к увеличению (на 23 %) нанотвердости до 38 500 МПа, модуля Юнга – на 67 %, который свидетельствует об увеличении энергии связей между атомами и прочности материала покрытия, а также к повышению износостойкости и снижению коэффициента трения покрытия до 0,07, удовлетворительной адгезионной прочности покрытия, т.е. в целом улучшает эксплуатационные характеристики всего твердого сплава.

The paper presents the new knowledge about influence of zirconiumas an ingredient of ionic-plasma (Ti, Zr)N coating which was spread on VK10 KS alloy. Ionic-plasma (Ti, Zr)N coating was spread with the use of “Kvant-6” equipment and separate cathodes made from 50 % Ti + 50 % Zr. N2 was used as a reaction gas. In this case two cathodes made from TiN were situated in the chamber of the equipment one against another but the cathode made from ZrN was between them. It was found out that introduction of zirconium into composition of the coating leads to increase of nanohardness as much as 23 % up to 38 500 MPa and Young’s modulus – as much as 67 %, which characterizes the increase of energy of atomic bonds and materials strength. Also it leads to increase of antifriction ability and decrease of friction constant of coating up to μ = 0.07, satisfactory adhesive strength of coating, i.e. generally improves the service features of the whole alloy.
