“…The assessment of wear resistance is usually based on the use of friction, grinding or impact systems. The known methods of determining abrasion resistance include the contact and surface abrasion methods used to assess adhesive and abrasive wear and the impact wear methods giving values of erosive wear [ 8 , 9 ].…”

Nitride-bonded silicon carbide is an alternative to steels resistant to abrasive wear. This paper presents the results of a nitride-bonded silicon carbide (SiC) wear test in diverse soil conditions. The test was performed on a “spinning bowl” test stand on three soil types: loamy sand, light loam and ordinary loam. The results were referred to the wear test for materials used to make parts working soil mass, i.e., abrasive wear-resistant steel, boron steel and C + Cr + Nb padding weld. The abrasive wear resistance of silicon carbide was shown to depend on the grain size distribution of the soil being worked. Silicon carbide showed the highest resistance in light soil. However, the padding weld showed higher wear resistance in the other soil conditions. Nitride-bonded silicon carbide had higher wear resistance than the steels under study in all of the soils. These findings are supplemented by an analysis of the condition of the worked surfaces after friction tests. The dominant wear methods in all abrasive masses were micro-cutting and furrowing.

“…Abrasive wear of brittle materials is often described with an equation which is used to calculate the volume of cut-out material along a scratch formed during a time unit [10] or a loss of mass after friction tests [11]. This issue has been tested in dry conditions for many years [8,9,[12][13][14][15][16][17].…”

“…This may be indicative of a different friction behaviour in the soil conditions specified. With regard to the structure, metal, rubber-metal and rubber tracks can be distinguished [ 2 , 3 ]. Among others, Hadfield cast steel is used for the links [ 4 ].…”

“…The question thus arises as to whether elastomer tracks exhibit a higher abrasion resistance compared to traditional metal track systems. To date, little information has been provided in the literature on the wear behaviour of materials used in track steering systems [ 3 , 8 ]. The complexity of the polymer wear process, in terms of its chemical composition, type of wear and the wear environment, has been presented, among others, in [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

This paper presents the results of comparative research on materials used for a track steering system in an abrasive soil mass. Two types of elastomer tracks were tested: a steel-rubber stave from an asphalt paver and a rubber overlay used in vehicles with a steel track chain. The results obtained were related to the wear of Hadfield steel. The tests were carried out on a “spinning bowl” stand in a natural soil mass, which consisted of two types of soil: light and heavy. It was shown that the resistance to abrasive wear depended on the grain size of the worked soil and the chemical composition of the materials. Rubber overlay was found to have the highest resistance index in all types of soils. It was made of high-density polyethylene, low-density polyethylene, ethylene acrylate/ethyl copolymer (ethylene acrylate 18%) and ethylene/propylene copolymer with an ethylene content of 60%. An analysis of the condition of the machined surfaces after friction tests complements the results presented.
