As a result, we obtained the scientific and practical results of the performed themes: the technology of the combined effects on the working surface of the product CSPD and further thermal diffusion nitriding, which ensures high functional properties of the artificial joint articulation; It proved the correctness of methods of tribological tests of friction pairs of hip implants in a "plane / ring"; first developed an effective technology the finish machining of the heads of the hip endoprosthesis with technically pure titanium; developed technological scheme CSPD spherical blanks by rolling flat surfaces; It found that the hardening of the surface layer of spherical blanks positive effect on the workability of the diamond-abrasive treatment by the method of free-lapping; the use of finite element method in the software package DEFORM-3D has allowed to develop a mathematical model of rolling process that allows you to determine the effect of technological factors on strain hardening
