THE EFFECT OF SURFACE FINISHING ON STRUCTURAL-CERAMIC FAILURE.

Abstract

A relationship between fracture strength and surface finish of brittle nonmetallic materials was examined and related to surface crack theory. An experimental illustration used AlSiMag 614, a 94% pure alumina with a near zero porosity. Specimen disks 3.625 + 0.031 in. in diameter by 0.085 + 0.010 in. thick were prepared, each having a specific surface finish. Testing was done with a biaxial ball and ring test. Observations were made regarding other materials and other abrasive powders. (Author)
