Abstract:
Among the well-known repair technologies for restoring bronze parts, there are practically no technologies using metal powders from non-ferrous metals. Electroerosive dispersion is an energy-efficient process that makes it possible to obtain powdered copper and bronze from machine-building waste with lower costs and environmental impact. (Research purpose) The research purpose is in evaluating the physical and mechanical properties of bronze powders obtained by electroerosive dispersion from machine-building waste, and justifying the possibility of their application in the technologies of repa

The high cost of metal powder materials and the energy consumption of the methods involved in their production have led to an increase in the cost of technologies for the restoration and hardening of parts.

Abstract:
The anti-friction properties of the plasma-sprayed powder coating based on copper PG-19M-01, proposed instead of the cast bronze sleeve made of 05Ts5S5 bronze, used in the coupling of the drive shaft and gear of the T-155 transfer case pumps, were proposed and investigated in the paper. X-ray phase analysis of plasma coatings from PG-19M-01 powder showed that the main phase in the coatings is a solid solution of aluminum in copper. X-ray microspectral analysis established that the composition of the coating is heterogeneous in thickness. The results of the conducted research and field tests sh

ABSTRACTDevelopment of devices storing and delivering high-energy power such as supercapacitors is necessary to assist intermittent sources of energy. Most of the commercial systems are carbon-based, but due to their high surface charge, oxides offer a valuable alternative for high-rate energy storage. Among them, layered transition metal oxides with mixed valence properties present both good electronic and ionic conductivities suitable for application to electrochemical applications intermediate between capacitors and batteries.

Abstract The effects of different powder compositions on the microstructure and properties of the sintered oil bearings were investigated. Three different types of powder were used for the comparative tests. The research conclusions show that three different types of raw material powders have different pore structures. In the case of mixed powders, the sintered samples have a self-lubricating function that can both store oil and supply oil to the friction surface through capillary pores. When the raw material is a mixed powder in which Cu powder is less than 75 μm, it has the best self-lubrica
