Title (EN) METHOD OF FABRICATING A HIGH-HARDNESS CASE HAVING LOGOTYPES, LETTERS OR FIGURES FOR PORTABLE DEVICES

Abstract: front page image
(EN)The present invention concerns a method of fabricating a high-hardness material having logotypes, letters or figures, which comprises the steps of: engraving a polished surface of a high-hardness material like zirconia ceramics or single crystal sapphire so as to form a figure, letter or logotype as an intaglio; filling the intaglio with glass frit; subjecting the surface to heat treatment; and polishing the surface again. The glass surface thus highly polished has hardness lower than the surrounding high-hardness material, thus hardly producing scratches, and the ornamental figure, letter or logotype is strongly united with the surrounding high-hardness material. The method produces variously colored and very beautiful letters, logotypes and figures of a high resolution, and therefore such high-hardness materials may be widely used as a material for covering portable devices or ornaments.
(FR)La présente invention concerne un procédé de fabrication de matière de dureté élevée ayant des logotypes, des lettres ou des chiffres, qui comprend les étapes consistant à : graver une surface polie d'une matière de dureté élevée comme une céramique de zircone ou un saphir monocristallin de manière à former un chiffre, une lettre ou un logotype en tant que gravure en creux ; remplir la gravure en creux avec une fritte de verre ; soumettre la surface à un traitement thermique ; et polir la surface à nouveau. La surface de verre ainsi hautement polie a une dureté inférieure à la matière de dureté élevée environnante, produisant ainsi difficilement des rayures, et le chiffre, la lettre ou le logotype ornemental est fortement unifié à la matière de dureté élevée environnante. Le procédé produit des lettres, des logotypes et des chiffres différemment colorés et très beaux d'une résolution élevée et ainsi de telles matières de dureté élevée peuvent être largement utilisées en tant que matière de couverture de dispositifs portables ou d'ornements.
(KO)본 발명은 로고, 글자 또는 문양을 갖는 고경도 재료 제조방법에 관한 것으로, 고경도 재료인 지르코니아 세라믹스 또는 단결정 사파이어와 같은 고경도 재료의 표면 연마된 표면에 문양, 글자 또는 로고를 음각으로 새기고 음각부를 유리 프릿으로 채우며, 열처리 후 다시 표면 연마하여 높은 광택의 유리질 표면이 주위의 고경도 재료보다 높지 않아서 스크래치가 생기기 어렵고 장식용 문양, 글자 또는 로고가 주위의 고경도 재료에 강하게 접합되어 우수한 미감을 갖는 다양한 색상의 글자, 로고 또는 문양을 높은 해상도로 형성할 수 있기 때문에 이러한 고경도 재료들을 휴대용 기기나 장식품의 외부 재료로 널리 활용할 수 있다.
