Development and characterization of a high abrasion resistant alumina–zirconia composite material

The addition of zirconia to alumina has been a subject of interest for quite a long time for many researchers. The sand abrasion of these composite materials, however, has rarely been discussed the literature. This paper reports the preparation of two different types of alumina–zirconia composites by adding either m-zirconia or t-zirconia, in different amounts, to the alumina matrix and the study of their various properties. The sand abrasion resistance test was carried out following the ASTM G-65 standard. The abrasion-resistant behavior shown by this test is correlated with the other properties of the as-prepared alumina–zirconia composites. This paper presents a high abrasion resistant alumina–zirconia composite material.
