FIELD: machine building.
SUBSTANCE: proposed unit comprises frame to support vacuum chamber communicated with vacuum pump, part fixture, gas flame torch for high-rate gas-dynamic sputtering arranged at 45 degrees to part surface, feeder of powder with shape memory effect to gas-flame torch, pyrometer to measure part temperature, module for ion-beam cleaning, appliance for surface straining to produce nanostructured layer, step-down transformer for additional heating of part surface, device to cool part surface to temperature of martensitic transformation at surface straining, and control device. Proposed unit comprises extra two magnetrons and metal ion implantation source secured on in vacuum chamber to be directed towards processed part. Surface straining appliance is composed of the press with moving top crossbar and fixed bottom crossbar arranged inside vacuum chamber. Note here that part fixture and surface cooler are mounted at said bottom crossbar. Gas-flame torch is rigidly secured inside vacuum chamber.
EFFECT: higher strength and wear resistance, expanded processing performances.
