STRUCTURAL MATERIALS, METAL SCIENCE

Shalimov Yu. N., Tokareva I. A., Evseyev E. P., Babkin V. F., Shalimov D. L. � Structural defect formation at cathode metal reduction

The paper deals with the interaction of hydrogen with structural defects. Found that defects decisive effect on the amount of accumulated hydrogen. Shown that increasing the number of defects is possible using pulsed electrolysis and heat treatment. Proposed technological modes of formation of metallic structures to efficiently store hydrogen.
Key words: hydrogen, hydride compound, anodic treatment, the pulse duty cycle of current, processes of mass transfer, accumulation of hydrogen

TECHNOLOGIES AND EQUIPMENT FOR MACHINING, PHYSICOTECHNICAL PROCESSING, NON-CUTTING SHAPING

Emelyanov S. G., Yatsun E. I., Shvets S. V., Remnev A. I., Pavlov E. V. � Build-up effect at turning operation on the tool life and on surface quality

The build-up during cutting is a part left over after the chip forming completion formed on the surface of the cutting edge in plastic domain. The shape and dimensions of the build-up characterize congestive plastic zone at the tip of the blade. Dead zone changes schema of forces application to the elements of the system of cutting, which affects the tool life. The build-up formed at the cutting edge and at the tips of the microroughnesses of the work surface has identical origin. The article shows that this type of microroughnesses cannot be predicted by calculation.

Khaldeyev V. N. � Assurance of form accuracy in electroerosion manufacturing process of spherical surfaces

Variation in electric parameters of electric erosion machining of spherical surfaces using a self-profiling tool method leads to the electrode gap value change. In its turn, it results in poor machined surface shape precision. To eliminate the shape error, the allowance, whose minimum value has been found analytically, should be specified for further machining. The experiment has supported the proposed technique validity.

SPECIAL TECHNOLOGIES

Kalyuta A. A., Rudzey G. F., Vakhnicheva M. G. � Fatigue life investigation of bolting and polymeric compensating fillers

We studied the effects of different compensation options of technological errors in the compounds (by steel insert, layers of polymer compensating filler) on static strength and fatigue life of the bolting samples from steel 30KhGSA under standard conditions, as well as after complex aging. We took filler VZ-27MV of different thickness (1 and 2 mm) and filler ZP-3 approx. 1 mm thick. Taking into consideration strength and life criteria we showed a possibility of the polymer compensating filler application in the connection of highly critical structural elements. Thickness range of the filler VZ-27MV was identified.
