INSTALLATION FOR PRODUCING MULTILAYER NANOSTRUCTURED COMPOSITE COATING WITH SHAPE MEMORY EFFECT ON STEEL CYLINDRICAL PART SURFACE Russian patent published in 2017 - IPC C23C4/08 C23C4/129 C23C24/08 B82Y30/00 

FIELD: metallurgy.

SUBSTANCE: installation for producing multilayer nanostructured composite coatings with shape memory effect on the cylindrical part steel surface contains a frame with the part clamping mechanism placed thereon with a cartridge and a tailstock, a part rotating mechanism, a vacuum chamber, which is connected to a vacuum pump and a gas-flame torch for high-speed flame spraying, placed on a longitudinal movement mechanism, a technological module for ion cleaning of the processed part with the power source, the first pyrometer to measure the part temperature placed in front of the high-speed flame spraying, a control device connected to the powder material feeding mechanism with the shape memory effect, a longitudinal movement mechanism of the gas-flame torch and the first pyrometer, a device for surface-plastic part deformation for forming nanostructured layer, installed on the longitudinal movement mechanism of the gas-flame torch, the second pyrometer installed in the area of the surface-plastic deformation, a step-down transformer providing additional heating of the part surface, a part surface cooling device installed on the longitudinal movement mechanism of the gas-flame torch, a powder material feeding mechanism with the shape memory effect, made in the form of three powder dosers with attritors for mechanical activation of powders connected to the vacuum chamber. The dispensers are configured to supply a mechanically activated powder to the channels of the gas-flame torch being three-channel and fixed on the longitudinal movement mechanism at an angle of 70-85° to the part surface.

EFFECT: increasing operational properties and reliability of multifunctional coatings on the parts providing enhanced adhesion strength, durability, and strength.
