“…4. Structure and microhardness distribution of the surface alloyed layer based on tin bronze: (a), (b)current strength 100 A, pre-coating 1 mm; (c), (d)current strength 140 A, pre-coating 0,5 mm.The basic layer structure of the Cu-Sn system is shown in fig.4 -b, as similar results are given in[27,29] with the main phases, including α-Cu, δ-Cu41Sn11. At a current strength of 140 A and a coating of 0.50 mm, the resulting layer does not have delamination, but there are many local zones rich in tin bronze with a size of several hundredths of a micrometer.…”

This paper presents a study of the characteristics and resistance to abrasive wear of surface alloyed layers during plasma heating of powder pre-coating of a mixture containing tin bronze and chromium carbide. It has been established that, depending on the composition of the mixture, the thickness of the coating, the processing mode, the resulting layers differ in structure, chemical and phase composition. The addition of chromium carbide with a mass fraction of 20% makes it possible to increase the microhardness of the alloyed layer based on tin bronze up to 700 HV with the formation of a martensitic structure. Tests for abrasive wear were carried out at a load of 5, 20, 50 N and with codirectional rotation of the holder to the abrasive wheel. The obtained results showed that the wear resistance of the Fe-Cu-Sn and Fe-Cr-C-Cu-Sn alloyed layers is higher compared to the Cu-Sn layer. In particular, the Fe-Cr-C-Cu-Sn layer is the best.

“…In terms of energy and technical and economic indicators, one of the effective methods of surface hardening of metals using highly concentrated sources is plasma alloying [8,[12][13][14][15][16][17][18][23][24][25][26][27][28][29][30][31][32][33][34]. Plasma treatment has a number of advantages: short processing time; high efficiency factor (efficiency); sequential heat treatment is not always required; low requirements for surface preparation before processing; and low cost of equipment [23,24,26,[35][36][37][38][39][40].…”

Depending on operating conditions, metals and alloys are exposed to various factors: wear, friction, corrosion, and others. Plasma surface alloying of machine and tool parts is now an effective surface treatment process of commercial and strategic importance. The plasma surface alloying process involves adding the required elements (carbon, chromium, titanium, silicon, nickel, etc.) to the surface layer of the metal during the melting process. A thin layer of the compound is pre-applied to the substrate, then melted and intensively mixed under the influence of a plasma arc, and during the solidification process, a new surface layer with optimal mechanical properties is formed. Copper-based alloys—Cu-X, where X is Fe, Cr, V, Nb, Mo, Ta, and W—belong to an immiscible binary system with high mechanical strength, electrical conductivity, and magnetism (for Fe-Cu) and also high thermal characteristics. At the same time, copper-based alloys have low hardness. In this article, wear tests were carried out on coatings obtained by plasma alloying of CuSn10 and CrxCy under various friction conditions. The following were chosen as a modifying element: chromium carbide to increase hardness and iron to increase surface tension. It is noted that an increase in the chromium carbide content to 20% leads to the formation of a martensitic structure. As a result, the microhardness of the layer increased to 700 HV. The addition of CuSn10 + 20% CrxCy and an additional 5% iron to the composition of the coating improves the formation of the surface layer. Friction tests on fixed abrasive particles were carried out at various loads of 5, 10, and 50 N. According to the test results, the alloy layer of the Fe-Cr-C-Cu-Sn system has the greatest wear resistance under abrasive conditions and dry sliding friction conditions.

“…Lead and tin-lead bronzes remain the most widely used material for monometallic journal bearings due to a combination of mechanical and tribological properties [1][2][3]. Considering that today about 23% of the world's energy is spent on overcoming friction forces and their consequences [4][5][6], the transition from bronze to aluminum-based alloys can become a driver for the development of the engine-building industry due to significant cost reduction of bearing manufacturing and further repair.…”

Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

et al. 2020

View full text Add to dashboard Cite

In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive analysis (EDX), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction analysis (XRD). In addition to the mass transfer of steel counterbody particles, phase transformations and new chemical compounds formed as a result of interaction with the lubricant were revealed. The release of elements, mainly magnesium and to a lesser extent zinc, from a solid solution of aluminum alloy was also observed, which indicates the occurrence of a non-spontaneous reaction with a negative entropy production.
