WEAR TESTING OF a-Al2O3 OXIDE CERAMIC IN A DIVERSE ABRASIVE SOIL MASS
Journal Title: Tribologia - Year 2014, Vol 253, Issue 1
Abstract
This paper presents a comparative study of the intensity of α-Al2O3 oxide ceramic sand 38GSA martensitic steel wear in three types of abrasive soil masses, i.e. loose sand, sandy clay and heavy clay. The tests were carried out under laboratory conditions on a “spinning bowl” wear machine. Based on the obtained results, the intensity of ceramic material wear was many times lower than 38GSA steel wear. It was found that the granulometric composition had an important effect on the intensity of α-Al2O3 ceramics wear. The lowest α-Al2O3 oxide ceramics wear was obtained during friction in sandy clay, and it was 1.5 times lower than in heavy clay and 1.9 times lower than in loose sand. Differences in the types of tribological wear, depending on the granulometric abrasive mass composition, are described.
