Badanie właściwości tribologicznych intermetali

Jasionowski R., Bryll K., Grabian J.

Archives of Foundry Engineering

2012

Vol. 12, iss. 1s

87--90

W pracy przedstawiono wyniki badań właściwości tribologicznych wybranych intermetali w warunkach tarcia suchego. Określono wartość zużycia masowego badanych materiałów i żeliwnej przeciwpróbki. Przeprowadzono analizę mikroskopową zmian stanu powierzchni w celu identyfikacji mechanizmów zniszczenia intermetali.

The paper presents tribological tests results of the selected intermetallics alloys in the conditions of dry friction . Tribological properties of the intermetallics alloys was investigated by mass wear. The microscopic examinations of the samples of intermetallics alloys in order to identify mechanisms of destruction have been determined.

Tribological properties of the Fe-Al intermetallic alloys after annealing

Garbala K., Patejuk A.

Archives of Foundry Engineering

2011

Vol. 11, iss. 2 spec.

43--46

In paper researching results of tribological proprieties Fe3Al intermetallic alloys after annealing are presented. Studies were conducted in the following environments: a water; an air and oil. For investigation purposes the tribotester pin-on-disk type with the contrsample made of steel 40H quenched and tempered was used. Tests were carried out with the following process parameters: pressure p = 2MPa and linear velocity (circuital) V = 0.46m/s. It was noted, that intermetallic samples with the small distinction in chemical compositions, annealed at different temperatures showed a large difference in the quantity of material loss in the all tested environments. Appropriately selected parameters of the intermetallic alloys annealing, provide their greater resistance to abrasion in the air and oil environments than in the case of steel.
