FIELD: machine building.
SUBSTANCE: procedure consists in application of layer of functional material possessing effect of shape memory on seats of shaft. Further, the applied layer is mechanically treated to a required dimension, vacuum annealed, cooled to room temperature with successive lowering temperature by means of cooling the applied layer with liquid nitrogen, and rolled with rollers in radial direction at this temperature of cooling. Upon rolling parts are fitted to seats of the shaft, and the shaft is heated to temperature of end of martensite transformation. Also the layer of functional material is applied by means of plasma overlaying the following mixture of powders, wt %: nickel 56-59, aluminium 23-26, iron 16-20 of dimension 90-120 nm.
EFFECT: eliminating mixing material of coating and material of shaft.
