Abstract

This study aims to develop hair cutter with zirconia($ZrO_2$) material whose machinability, corrosion resistance, wear resistance and bio-compatibility are excellent by comparing iron hair cutter. Ultra-thin zirconia cutter with the thickness of 0.253mm is manufactured through the optimization of design, molding, sintering, grinding and grinding process. With observation result of cutter specimen by use of scanning electron microscope(SEM), formability and process of cutting face are shown to be good. It is also evaluated with sufficient merchantability by cutting test results. The cutter process technology of thin zirconia can be utilized at the development of high value-added beauty appliances like razor, beauty-razor and eye brows-razor for woman by use of study result.

본 연구에서는 스틸 헤어커터와 비교하여 절삭성, 내식성 내마모성이 우수하고 생체친화성이 뛰어난 소재인 지르코니아($ZrO_2$)를 원료로 하는 헤어커터 개발을 위하여 설계, 성형, 소결, 연마가공 최적화를 통해 두께 0.253mm의 초박형 지르코니아 커터를 제작하였다. 커터 시편을 전자주사현미경(SEM)으로 관찰한 결과, 성형성과 절삭면 가공이 양호한 것으로 나타났으며, 절단시험을 통해 상품성이 충분한 것으로 평가되었다. 본 지르코니아 커터 가공기술 연구결과를 이용하여 면도기, 여성용 제모기, 눈썹정리기 등 고부가가치 미용기구 개발에 활용 될 수 있다.
