Description

티타늄 합금 체결기{TITANIUM ALLOY FASTENER}Titanium Alloy Fasteners {TITANIUM ALLOY FASTENER}

전술한 종래의 나사 체결기(10)는 프레스 단조(press forging) 수단에 의해 연질성 페라이트(soft ferrite)로 제조될 수 있다. 그러나, 연질성 페라이트는 산화되기 쉽고, 강도(strength)가 낮으며, 산 저항성(이하 내산성)과 알라키염 저항성(이하 내알카리성)이 낮다. 양질의 강도를 제공하기 위해, 나사 체결기(10)는 고경도(hardness) 재료로 제조될 수도 있다. 그러나, 페라이트계(ferrite series) 재료의 경도는 그 카본 함유량에 의존한다. 카본 함유량이 낮은 페라이트계 재료는 경도가 상대적으로 높지만, 깨지기 쉬운 성질(이하, 취성 또는 피로도)도 높다. 경 도가 높은 페라이트계 재료로 제조된 태핑 나사(104)는 취성이 높기 때문에 금속판 부재(50)로 박아질 때 깨지기 쉽다.The conventional screw fastener 10 described above can be made of soft ferrite by press forging means. However, soft ferrite is easy to oxidize, has a low strength, and has low acid resistance (hereinafter acid resistance) and alkaki salt resistance (hereinafter alkali resistance). To provide good strength, the screw fastener 10 may be made of a hardness material. However, the hardness of the ferrite series material depends on its carbon content. Ferritic materials having a low carbon content have a relatively high hardness, but also have high fragile properties (hereinafter, brittleness or fatigue). The tapping screw 104 made of a high hardness ferrite material is brittle because of its high brittleness and is easily broken when being driven into the metal plate member 50.
