Fatigue Properties of Borosilicate Glass Coated with Ceramics and Effect of Proof testing on Life Distribution

摘要

In this work, a borosilicate glass was coated with ceramic thin films by sputtering method. Roughness, hardness and static bending strength were measured as static characteristics of coated glass. Fatigue tests of coated glass were conducted under three-point bending. Although a large scatter was observed in fatigue life distributions, it was clarified that the fatigue strength was improved by coating ceramic thin films on glass. Specimens having lower lives in fatigue life distribution were adequately removed by proof testing. Therefore, it was suggested that proof testing for fatigue was effective as a screening procedure.
