초록

Stainless steel 316L (STS 316L) is widely used as a material of biopsy needle. However it has a
side effect that tissue can be damaged by electrochemical operation between tissue and STS
316L. Many studies have been made on the ceramic coating of biopsy needle to reduce the side
effect. In this study, STS 316L was coated with three bioceramics, Al2O3, SiO2 and ZrO2 using a
RF magnetron sputtering method. The effects of ceramic coating on the electrical conductivity
and coating strength of ceramic-coated STS 316L were investigated. The results showed that the
electrical conductivity of ceramic-coated STS 316L was much lower than that of uncoated STS
316L. The coating strength of ZrO2-coated STS 316L was 30% and 70% higher, respectively than
those of Al2O3-coated STS 316L and SiO2-coated STS 316L.
