Tribological Properties of AlSi17Cu5Mg Alloy Modified with CuP Master Alloy with Various Speeds of Friction

Piątkowski J., Wieszała R.

Archives of Foundry Engineering

2016

Vol. 16, iss. 1

45--48

The paper presents the influence of modification with phosphorus (CuP10) on the tribological properties of the alloy AlSi17Cu5Mg coupled abrasively with cast-iron EN GJL-350. Tests of coefficient of friction and wear of mass were conducted on tribological tester T-01. An important aspect in the assessment of the tribological properties is the analysis of initial material microstructure in reference to silumin which underwent modification with phosphorus. It was found that the difference in structure of tested materials, mainly sizes of primary silicon crystals significantly influences the tribological properties whereas the speed change of the friction knot does not have such big influence.

Frictional heating of the extrusional equipment working parts at processing of high - filled compositions

Analytical equations of energy dissipation along friction surfaces during the extrusion of high - filled compositions are obtained. On example of processing of wood-plastic compositions it is shown, that the contribution of friction forces to heating of material is comparable with the contribution of external electric heaters.

Uzyskano analityczne równania rozproszenia energii na powierzchniach tarcia podczas wyciskania wysoko wypełnionych kompozytów. Pokazano, na przykładzie przeróbki kompozytu tworzywo sztuczne - drewno, że udział sił tarcia w nagrzewaniu materiału jest porównywalny z udziałem zewnętrznych grzejników elektrycznych.
