Antifriction Alloys

Potential relations of tribological characteristics of aluminum antifriction alloys with their compositions and mechanical properties were investigated. In this regard, the properties of eight aluminum alloys containing tin from 5.4% to 11% doped with lead, copper, silicon, zinc, magnesium, and titanium were studied. Mechanical properties such as hardness, strength, relative extension, and impact strength were analyzed. Within the tribological tests seizure load and wear of material were evaluated and secondary structures were studied afterwards. The absence of a definitive correlation between tribological behavior and mechanical properties was shown. It was determined that doping tin over 6% is excessive. The seizure load of the alloys increases with the magnesium content. Secondary structures of the alloys with higher wear rates contain one order less magnesium and tin.

Antifriction Properties

The most important features of the self-lubricating bearings are the antifriction properties such as friction coefficient and wear resistence and some mechanical properties such as hardness, tensile strength and radial crushing strength. In order to improve these properties new antifriction materials based on iron-copper powders with several additional components (tin, lead and molybdenum disulphide) have been developed by PM techniques. To find the optimal relationship between chemical compositions, antifriction and mechanical properties, in this paper a mathematical model of the sintering process is developed, which highlighted the accordance of the model with data by regression analysis. For the statistical processing of the experimental data the VH5 hardness values of the studied materials were considered. The development of mathematical model includes the enunciation of the model, the establishment of the performance function (optimization) and the establishment of the model equations and verifying. The accordance of the model with experimental data has been highlighted by regression analysis

Discuss how iron, copper and magnesium alloy and rare earth cerium influence the electrical and mechanical properties of aluminum conductor using the orthogonal test, to thereby get the best alloy composition that meets the requirement; through test analysis on the conductivity, intensity and elongation at break of aluminum conductor with the best alloy composition, discuss the influence of different annealing temperature and holding time on their performance. The results show that: the best material composition of the aluminum alloy conductor would be 0.25% Fe, 0.40% Cu, 0.05% Mg, 0.30% Ce, 0.008% B, and aluminum and inevitable impurities. The intensity, elongation at break and conductivity of this aluminum conductor would be 110N/mm2, 30.0% and 62.2%IACS respectively. The best annealing process parameters are annealing temperature of 310°C, and holding time for 30min, direct air cool. The intensity of aluminum conductor processed is 129 N/mm2, and the elongation at break, resistivity, and conductivity are 15.0%, 2.782×10-8Ω•m and 62%IACS respectively. The mechanical properties and conductivity of this aluminum conductor both comply with the requirements of wire and cable conductor cores.
