This work is devoted to the development of a heat treatment technology in the manufacture process of cold deformed VT16 and VT35 fasteners with the diameter of 16mm or more. This work also investigated the influence of various types of lubricants on the friction coefficient at the “metal-tool” interface during cold deformation operations.

A comparison was made of the properties of porous coatings obtained by ion-plasma spraying methods, 3D-coating obtained by direct laser metal deposition (DLMD), as well as a GRIPTION® and POROCOAT® coating. The influence of various methods of obtaining a porous coating on the porosity and structure of the coating, as well as the effect of thermal hydrogen treatment (THT) on the adhesion strength of the titanium coating was determined.
