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 aim of this research was to study the effect of bottom ash additions to a bronze-graphite composite on the sintering behavior, as well as on the resultant physical, mechanical and tribological properties. The composites were produced by a powder metallurgy technique from prealloyed Cu-10Sn bronze powder, graphite powder and milled bottom ash powder. The compositions studied were Cu-10Sn bronze with constant 5 wt.% graphite, and 0-20 wt.% bottom ash. Samples were die compacted under 795 MPa and sintered at 850 oC for 30 minutes in an open atmosphere furnace. It was found that the sintered d

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. One method of solving this problem is the recycling of powders. A promising method for processing the waste from machine-building industries, including those utilizing non-ferrous metals and alloys, is electroerosive dispersion. Metallic powders from secondary raw materials obtained in this manner have good physical and mechanical properties, and their cost is two to three times less than t

The results on the impact of additives on the ultra-fine composite powder system, obtained by MASVS on the tribotechnical properties of friction material based on tin bronze with 12 % of tin are presented. It is shown that the powder additive in the range of 0.5–2.5 % increased the dynamic friction coefficient from 0.040 to 0.051. The introduction of a 1.5 % composite powder reduced the surface roughness of the counter body from 2.9 to 0.9 μm. The change in the tribotechnical properties is due to the structural changes in tin bronze, the additive particles, the surface layer of the friction ma

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. This work focuses on lamellar oxide bronzes based on cobalt MxCo

One of the main problems in the production of bimetals is associated with the difference in the physico-mechanical and structural properties of the materials being joined. Both solid-phase and liquid-phase methods are used to obtain bimetals. The main technological task is to create conditions for the formation of a transition zone between the working layer and adhesively bound substrate. We analyzed the known methods for producing compact and powder bimetals (insert molding, diffusion welding in the solid phase, infiltration, hot isostatic pressing, etc.).

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

During the operation of agricultural machinery, machine parts and their connections lose their operability, which requires their replacement.

The presence of non-ferrous metal and alloy parts in the equipment, and in particular bronze, makes the issue of restoration even more urgent due to the high cost of such parts. Methods using powder materials are particularly successful in restoring worn parts. It is characteristic that in order to reduce the cost of such technologies, it is possible to resort to recycling of metal waste
