The substantiation of the tool parameters and the technology of the simple de-formed formation of friction surfaces

The requirements for the technology of treating friction surfaces in nominally stationary and inactive assemblies of titanium blades of low-pressure compressors of gas turbine engines (GTE), increasing their wear resistance are given. The effectiveness of the change in the combined technology of the hardening deformational deformation (UDF) of friction surfaces is shown, when the deforming tool is rolled in the form of a rolling roller with wedge indenters along a closed contour at the periphery, followed by the application of solid lubricating coatings. The hexagonal shape of the cells is calculated and experimentally proved and evaluated by different parameters of the deforming tool; The size of the elementary cell site; Depth and angle of inclination of side faces of profile grooves; Diameter and length of the rolling roller; Knurling force.
