| Research Abstract |
In the present work, a borosilicate glass was coated with ceramic films by a radio-frequency (RF) magnetron sputtering method, and roughness and hardness were measured as surface characteristics of coated glass. A new procedure to estimate the strength of coated materials was proposed by incorporating relative hardness and roughness with sputtering time. The strength in experiments was well estimated by using the proposed procedure. Minimum fatigue life of each coated glass was well expressed as a power function of the mean strength.
