The continuous technological development requires the use of modern materials also in agricultural engineering. Knowledge of the characteristics of tribological materials pairs cooperating with each other is useful for developing sliding nodes of agricultural machinery. Tribological properties of materials should be assessed for selection of technological materials beyond the economic criterion. The...
Artykuł dotyczy analizy charakterystyki zużycia tribologicznego odlewniczych stopów Al-Si stosowanych w przemyśle motoryzacyjnym. Przedmiot badań stanowiły: AlSi6Cu, AlSi7Mg, AlSi12CuNiMg i AlSi20CuNi. Testy tribologiczne prowadzono w warunkach tarcia technicznie suchego. Badania zrealizowano na tribotesterze typu „ball-on-disc”. Badano współczynnik zużycia i współczynnik tarcia stopów, a ślady zużycia...
Pomimo wysokich kosztów wytwarzania, materiały kompozytowe na osnowie aluminium są coraz częściej stosowane na tłoki silników spalinowych. W pracy przedstawiono badania zużycia - kompozytu zbrojonego cząstkami SiC w stanie surowym i po obróbce cieplnej typu T6, powodującej sferoidyzację obszarów eutektyki oraz podwyższenie twardości - w warunkach tarcia ze smarowaniem w postaci różnych środowisk....
The change of the tribological properties after ion implantation of two kinds of tool steels: chromium—NC11LV and chromium free—N11E was studied. Nitrogen and argon implantations were carried out in different orders at energy 120keV with the doses 5×1017 and 1×1017ions/cm2, respectively. Significant improvement of abrasive wear and friction coefficient as well as microhardness of NC11LV steel was...
