Fine Ceramics that exhibit excellent hardness also greatly surpass most metals in wear resistance. During wear resistance tests, small glass beads were continously sprayed at high speeds onto Fine Ceramics and metals for extended periods of time. The Fine Ceramics displayed only about 10 percent of the abrasion observed in the stainless steel samples. Additionally, during a test in which disks with Fine Ceramics and metals attached were continously rotated in wet sand for eight hours, the Fine Ceramics displayed considerably less abrasion.
