Investigation of Abrasive Wear Behavior of Industrial Wastes on Al 6061 Material Using Rubber Wheel Abrasion Test (RWAT) Method
In this study, the abrading characteristics of the slags, generated in
the form of industrial waste during raw iron, steel and ferrochromium
ore production, are investigated. Granulated blast furnace slag (GBFS),
basic oxygen furnace slag (BOF) ferrochromium slag (FCS) and commercial
Al2O3 powder were used during the tests. Abrasion tests were conducted
using Rubber Wheel Abrasion Wear (RWAT) method. Al 6061 was chosen as
the counter body material. The tests were conducted under 25, 50, 75 and
100 N loads with 100 r/min rubber wheel rotational speed. The highest
rate of abrasion was obtained from GBFS under all loads as a result of
the conducted tests. Under high loads, the abrading performance of FCS
reached that of the commercial Al2O3 powder. BOF was found to have no
abrading capability. Surface morphology and SPQ (spike
parameter-quadratic fit) value were as effective as the particle
hardness in the evaluation of abrading performance. As dominant wear
mechanisms, spalling, ploughing and micro-scratch formation were
observed on the specimens abraded with GBFS and Al2O3, whereas severe
plastic deformation-induced extrusion was observed on the specimen
abraded with FCS
