Abstract:
A truck's gearbox friction rings restoring process by hot 3D stamping was developed and adopted for implementation. Using this recovery method in combination with subsequent synchronizer rings mechanical processing allows restoring up to 95% resource of worn parts. It was established that section of a stamp's deforming element for axisymmetrical parts restoring should be a one-way wedge with a sloping face facing the reconstructed surface. The most significant factors influencing the transmission gearbox synchronizer rings restoring process are: stamp deforming element thickness, plunging dept

Abstract:
The paper is devoted to the search for technological methods of increasing the resistance of the stamp tool for hot deformation. New non-standard combinations of cyclization schemes and parameters of thermocycling processing within the regime were developed. This is allowed the creation of managed structural states in the metal due to the grinding of grain, the creation of high density of defects, and the acceleration of diffusion processes to effectively manage the structure, increase the mechanical, operational properties and prevent the destruction of the working surfaces of the tool.

The aim of the study is to create a theoretical basis that allows to calculate the forces of hot plastic deformation of the piston pin. One of the promising methods of restoring the piston fingers of the connecting rod - piston group of internal combustion engines is the method of hot plastic deformation. The process of restoring the piston fingers by hot plastic deformation can increase their strength and, in particular, fatigue strength.

Abstract:
The stamps for hot deformation are widely adopted in industry. In use they are affected by high temperatures, tension (close to a fluidity limit) and variable thermal loadings. High-hardenability tool steels with high mechanical characteristics are used for stamps production. In this article, the possibility of use of 5KhNM steel for this goal is considered. One of technological operations at production of stamps is training in oil. It is rational to apply volume and superficial hardening, in particular chemical heat treatment, to improve operational characteristics of stamps, including wear r

Abstract:
Stamping of round hollow semi-finished products by hot reverse extrusion from round and square workpieces is the first stamping step in the manufacture of hollow products for special purposes. These products require certain mechanical properties along the wall height and in the bottom part, which can be achieved by working out the metal structure by plastic deformation. The bottom part is worked out by reverse extrusion. The wall properties are obtained in the following stages of drawing the semi-finished product with thinning after extrusion. The use of square workpieces results in more inten

Abstract:
The article is devoted to the substantiation of technological foundations for the restoration of extremely worn-out, metal-consuming, and resource-consuming parts, in a method consisting of applying a compensating metal wear with subsequent plastic deformation. Currently, there are no technologies for their restoration in a repair facility that guarantee the resilience of the factory product. The proposed technological process of repair consists of butt welding onto the end of the spline semi-axle shank, compensating for the wear of the metal, the volume of which takes into account the losses

Abstract:
Nanoscale patterned gold (Au) surfaces are promising for a wide range of applications such as bio/chemical sensors and high-performance electrodes. However, pattern formation by conventional methods, which typically involves the use of resist, is complex, cost-consuming, and poses a high environmental burden. In this study, we report an investigation into the interfacial chemical reaction occurring between the polymer electrolyte membrane (PEM) and Au surfaces and its application for microscale pattern formation. Introducing a PEM instead of a liquid electrolyte can realize solid-state electro

Abstract:
In [1], the innovative technology is proposed for pulsed detonation stamping of thin sheet parts. The technology consists in periodically exposing a workpiece to detonation waves and hot gaseous detonation products. The distinctive feature of the technology is the absence of a punch (the mating part of a pro¦led matrix). Compared to the detonation of condensed explosives, the use of gaseous detonation for stamping allows multiple periodic gasdynamic and thermal impact on a workpiece and simpli¦es the execution of technical supervision requirements.
