The effect of aging on wear characteristics of rheocast-leaded aluminum alloys

Development of electroless composite coatings by using in-situ co-precipitation followed by co-deposition process

“…This is in agreement with electroless Ni-B coating as well. [18,19] In the present investigation, it is noticed that the rate of deposition decreases with an increase in loading factor. Figure 5 shows the coating weight observed for different concentrations of the coprecipitation reactants, in terms of concentration of AlCl 3 , i.e., n ϫ concentration of ZrOCl 2 , where n is the ratio of weight of AlCl 3 to that of ZrOCl 2 and is found to be 3.31.…”

Significant improvement of wear properties by creating micro/nano dual-scale structure in Al–Sn alloys

“…Wear properties were measured in the ambient environment in an MM-200 wear test machine similar to that used by Timken [29]. The wear test was a block-on-ring mode, i.e., a polished square plane of a block sample with dimensions of 10 Â 10 Â 3 mm 3 was in contact with a rotating steel ring under a certain load.…”

Microstructure and morphology of Al–Pb bearing alloy synthesized by mechanical alloying and hot extrusion

“…In addition, adding elements, such as Si, Cu and Sn to strengthen the Al matrix, the wear properties of Al-Pb alloys can be further improved [4]. It was found that corrosion resistance of the Al-Pb alloys could be improved by adding tin.…”

“…It was found that corrosion resistance of the Al-Pb alloys could be improved by adding tin. Silicon is thought to have several benefits, including improved wear resistance, seizure resistance, strength of matrix and surface condition of the contact face [4][5][6]. However, aluminum and lead are virtually insoluble from each other in the solid state at room temperature and have very wide miscibility gap in the liquid state even at high temperature.…”
