Abstract:

Currently, lead and tin bronzes are most often used for the production of bearings, which is due to their high level of tribotechnical properties and reliability in operation. At the same time, the ban in the European Union on the use of lead in any products led to the need to find environmentally safe bronzes with a similar or increased level of tribotechnical properties. A promising way to solve this problem is BrO3A3 bronze, the microstructure of which fully meets the requirements for bearing alloys. However, to date, the tribotechnical properties of BrO3A3 bronze have not been investigated

Abstract:

The structure, mechanical properties and wear resistance of hypereutectoid steel containing 0.09-8.97 wt. %copper were studied. It is found that an increase in copper increases lamellar pearlite microhardness. Triboengineering testings under conditions of sliding friction show that wear resistance of hypereutectoid steel alloyed with 8.97 wt. % copper is ~3.5 times higher than the wear resistance of bronze and by ~23 % higher than the wear resistance of bearing cast iron. Under conditions of friction on fixed abrasive particles a relative wear resistance of the hypereutectoid steel alloyed wit

After annealing in vacuum, the mechanical properties of the alloy decreases due to vaporization of alloying element. In addition, the softening of matrix induces decreasing the wear resistance dramatically. In contrast, high mechanical properties were observed in the alloy annealed in air and in nitrogen atmosphere. In particular, a large smearing of lead in the alloy annealed in air atmosphere was observed and was affected on the enhancement of wear resistance. Conse

Abstract:

The dry sliding behavior of various 2xxx and 7xxx aluminum alloys with and without nickel-aluminum bronze-coatings were evaluated for industrial sheave wheel applications involving steel cables. In order to simulate the wear caused by a cable within the sheave groove, wear tests were conducted using a pin-on-ring wear test configuration. For these tests, the various aluminum alloys were worn against a 387 steel using an interfacial pressure of 13.9 MPa and a sliding velocity of 9.42 m/s. Results indicated that for the conditions studied, the 7xxx aluminum alloys exhibited a superior wear resis

The results indicate that the magnetic field promotes the movement of low-angle grain boundaries less than 2° and splices to form subcrystals or fine crystals, which reduces the mean grain size of the alloy.
