Abstract
Description
본 발명은 흑색 금속 강판 및 이의 제조방법에 관한 것이다.The present invention relates to a black metal sheet and a method of producing the same.
프리미엄 가전시장에서 시각적, 기능적 관점으로부터 흑색 금속 강판의 요구가 높아지고 있다. In the premium consumer electronics market, there is a growing demand for black metal plates from a visual and functional point of view.
강판의 표면을 흑색화하는 방법으로서는, 강판의 표면에 흑색 도료를 도포하여 흑색 도막(塗膜)을 형성하는 방법이 있다. 그렇지만, 상기 분야에는, 내식성의 관점에서 용융 Zn 도금이나 용융 Al 함유 Zn 도금, 용융 Al, Mg 함유 Zn 도금 등의 도금을 실시한 도금 강판이 사용되는 것이 많고, 이러한 도금 강판의 표면은 금속 광택이 있는 은백색의 색조를 가지고 있다. 따라서, 흑색 도료의 도포에 의해 의장성 높은 흑색 외관을 얻기 위해서는, 도막을 두껍게 하여 베이스 색을 은폐하지 않으면 안되어, 도장 코스트가 비싸게 되어 버린다. 또, 이와 같이 도막을 두껍게 하면, 스폿 용접 등의 저항용접을 행할 수 없게 되어버린다는 문제도 있다.As a method of blackening the surface of the steel sheet, there is a method of forming a black coat (coating film) by applying a black coat on the surface of the steel sheet. However, from the viewpoint of corrosion resistance, plated steel sheets plated with molten Zn plating, molten Al-containing Zn plating, molten Al, Mg-containing Zn plating, etc. are often used in the above-mentioned fields. It has silver-white hue. Therefore, in order to obtain a black appearance with high decorative effect by application of a black paint, the coating color must be thickened to conceal the base color, and the coating cost becomes expensive. In addition, if the coating film is made thick as described above, resistance welding such as spot welding becomes impossible.
즉, 종래의 티타늄 발색 기술은 양극산화법으로 티타늄 표면의 산화막 두께를 변화시키거나 질화막을 생성시켜 표면 발색을 유도하였다. 특히, 흑화 처리 방법으로 티타늄을 불화수소산 수용액에 침지해 흑색 피막을 형성하는 방법(일본 특허 제1190252호), 티타늄 표면에 구리를 석출시켜 흑색화 하는 방법(일본 특소공 58-23469호 공보) 등이 있다. 이들 방법은 흑색 피막이 박리한다든가, 명도를 낮추기 위해 가열 처리를 실시하지 않으면 안 된다고 한 문제가 있다.That is, in the conventional titanium coloring technology, anodic oxidation method is used to change the thickness of the oxide film on the titanium surface or generate a nitride film to induce surface color development. In particular, a method of immersing titanium in an aqueous solution of hydrofluoric acid to form a black coating (Japanese Patent No. 1190252), a method of precipitating copper on the surface of titanium by blackening (Japanese Examined Patent Publication No. 58-23469), etc. . These methods have a problem that the black coating must be peeled off or the heat treatment must be carried out to lower the brightness.
반면, 용융아연계도금강판에서는 내식성 향상을 위해 도금한 도금층에서 스팟성 흑변화가 발생하여 이를 억제하기 위한 연구가 1980년대 이전부터 진행되었다. 아연계도금강판의 도금층은 Al 또는 Mg을 미량 함유한 Zn 합금층으로, 표면 산화 시 Al 또는 Mg이 우선 산화함에 따라 Zn이 불완전 산화하고 또한, 산화막에 수산화물질이 생성되어 흑변화가 발생하는데, 이 때 피막이 박리되는 문제가 있다. On the other hand, in the case of hot dip galvanized steel sheets, researches were carried out in the 1980s to suppress the occurrence of spot blackness in the plated layer to improve the corrosion resistance. The plated layer of zinc-plated steel sheet is a Zn alloy layer containing a small amount of Al or Mg. When Al or Mg is oxidized at the time of surface oxidation, Zn is incompletely oxidized and hydroxide is generated in the oxide film, At this time, there is a problem that the film peels off.
이에, 상기와 같은 문제를 해결하기 위한 연구가 시급한 실정이다.Therefore, research for solving the above problems is urgent.

일 구현예는 흑색화된 티타늄 강판을 제공하며, 상기 흑색화된 티타늄 강판은 티타늄 기판; 및 상기 티타늄 기판 상에 위치하는 Ti-Zn 합금층;을 포함하고, 상기 Ti-Zn 합금층은 TiZn2를 포함한다.One embodiment provides a blackened titanium steel sheet, wherein the blackened titanium steel sheet comprises a titanium substrate; And a Ti-Zn alloy layer positioned on the titanium substrate, wherein the Ti-Zn alloy layer comprises TiZn 2 .
도 2 내지 도 4에서 보는 바와 같이, 상기 TiZn2를 포함하는 Ti-Zn 합금층은 모재인 티타늄 기판과의 격자 정합성이 높아, 종래 문제점인 박리 현상 등을 해결할 수 있다.As shown in FIGS. 2 to 4, the Ti-Zn alloy layer containing TiZn 2 has high lattice matching with the titanium substrate, which is a base material, and can solve the peeling phenomenon which is a conventional problem.

상기 흑색 금속 강판의 명도는 L*값으로 30 이하일 수 있다.The lightness of the black metal sheet may be 30 or less in L * value.
다른 일 구현예는 흑색화된 티타늄 강판의 제조방법을 제공한다.Another embodiment provides a method for producing a blackened titanium steel sheet.
상기 흑색화된 티타늄 강판의 제조방법은, 티타늄 기판을 준비하는 단계; 상기 티타늄 기판 상에 Ti 및 Zn을 포함하는 화합물을 피막화시켜 Ti-Zn 피막을 생성시키는 단계; 상기 Ti-Zn 피막이 생성된 티타늄 기판을 밀폐 용기 안에서 수증기와 접촉시켜, 수증기 산화시키는 단계;를 포함한다.The method for producing a blackened titanium steel sheet includes the steps of: preparing a titanium substrate; Forming a Ti-Zn coating on the titanium substrate by coating a compound containing Ti and Zn on the titanium substrate; And a step of subjecting the titanium substrate on which the Ti-Zn coating is formed to steam oxidation in contact with water vapor in a closed container.
상기 흑색화된 티타늄 강판의 제조방법은, 종래의 양극산화법으로 흑색화 하기 어려운 티타늄의 표면에 격자 결합력이 높고 내식성 확보가 가능한 물질 피막을 생성시키고 수증기 산화하여 흑색화하는 방법이다. The method of producing the blackened titanium steel sheet is a method of blackening the surface of titanium which is difficult to be blackened by the conventional anodic oxidation method, by forming a material film having high lattice bonding force and ensuring corrosion resistance and by steam oxidation.
일 구현예에 따른 제조방법은 종래 제조방법과 비교하여, 티타늄 표면에 티타늄을 함유한 아연 화합물을 건식 처리하여 피막화한 후, 수증기 산화하여 아연의 불완전산화를 유도하는 것을 특징으로 하기 때문에, 표면 밀착성이 우수하고, 제조 제정성 및 재현성 또한 보다 우수하다.The method according to an embodiment of the present invention is characterized in that, compared with the conventional manufacturing method, the zinc compound containing titanium on the surface of titanium is dry-treated to form a film, and then steam oxidation is performed to induce incomplete oxidation of zinc. Adhesion is excellent, manufacturing stability and reproducibility are also excellent.
용융아연계 도금강판에서 발생하는 스팟성 흑변은 용융아연계 도금강판을 산화 분위기에 노출시키면 Zn에 함유된 Al 또는 Mg이 우선 산화되면서 Zn이 불완전 산화됨에 기인한다. 상변화에 대한 열역학적 고찰을 해보면, 산화 시 Mg은 MgO, 또는 MgOH가 상안정성을 나타내며, Zn는 ZnO 상이 안정하다. Spots that occur in hot dip galvanized steel sheets are caused by the incomplete oxidation of Zn as a result of the oxidation of Al or Mg contained in Zn if the galvanized steel sheet is exposed to an oxidizing atmosphere. Thermodynamic considerations for phase change show that Mg is MgO or MgOH phase stable at the time of oxidation and ZnO phase is stable.
티타늄 또한 산화 또는 수산화물질을 표면에 잘 생성시키는 금속으로 알려져 있다. 같은 원리로 열역학적 상안정성을 고찰해보면 티타늄 또한 TiO 또는 TiH4 상이 안정하며 Zn보다 우선 산화하여 티타늄 산화물 또는 티타늄 수화물을 만들어 Zn의 불완전 산화를 유도한다. (도 5 내지 도 8 참조)Titanium is also known as a metal that produces oxidation or hydroxide on the surface well. Considering thermodynamic stability with the same principle, titanium also contains TiO 2 or TiH 4 Phase is stable and oxidizes preferentially to Zn to make titanium oxide or titanium hydrate to induce incomplete oxidation of Zn. (See Figs. 5 to 8)
또한, Al 또는 Mg을 함유한 용융아연계 도금강판은 응고 시 MgZn2 화합물을 생성시키며, 이 화합물의 격자상수는 a = 0.52234 nm, b = 0.52234 nm, c = 0.85562 nm, α = 90 °, β = 90 °, γ = 120 ° 이다. Further, the molten zinc plated steel sheet containing Al or Mg produces MgZn 2 compound upon solidification, and the lattice constants of this compound are a = 0.52234 nm, b = 0.52234 nm, c = 0.85562 nm, = 90 [deg.], And [gamma] = 120 [deg.].
한편, 티타늄은 격자상수가 a = 0.328 nm, b = 0.328 nm, c = 0.328 nm, α = 90 °, β = 90 °, γ = 90 ° 으로 용융아연계 도금으로 티타늄의 흑색화를 유도한다면 MgZn2 화합물의 모재와의 격자 부정합성으로 기존 공정의 문제점인 박리현상이 발생할 가능성이 높다. On the other hand, if the lattice constant of titanium is induced by blackening of the titanium by molten zinc plating at a = 0.328 nm, b = 0.328 nm, c = 0.328 nm, α = 90 °, 2 compound with the parent material, there is a high possibility of peeling phenomenon which is a problem of the existing process.
반면, 같은 원리로 Ti-Zn 피막은 TiZn2 화합물을 생성시키며, 이 화합물의 격자상수는 a = 0.304 nm, b = 0.304 nm, c = 1.068 nm, α = 90 °, β = 90 °, γ = 90 ° 로 티타늄의 격자상수와 매우 유사하다. 따라서, 모재인 티타늄 기판과의 격자 정합성이 높은 Ti-Zn 피막을 생성시키면 박리 현상 문제를 해결할 수 있다.On the other hand, on the same principle, the Ti-Zn coating produces a TiZn 2 compound with a lattice constant a = 0.304 nm, b = 0.304 nm, c = 1.068 nm, α = 90 °, 90 ° and is very similar to the lattice constant of titanium. Therefore, if a Ti-Zn coating having high lattice matching with a titanium substrate as a base material is produced, the problem of peeling can be solved.
즉, 종래에는 용융 Al, Mg 함유 Zn 도금 강판 등을 밀폐 용기 속에서 수증기와 접촉시켜 MgZn2 화합물을 생성시켰는데, 이는 모재인 티타늄 기판과의 격자 부정합성으로 인해 박리 현상이 발생하였으나, 일 구현예에 따르면 TiZn2 화합물을 생성시켜, 궁극적으로 모재인 티타늄 기판과의 격자 정합성이 높은 Ti-Zn 피막을 형성함으로써, 박리 현상 문제를 해결할 수 있다.In other words, conventionally, MgZn 2 compounds were produced by contacting molten Al, Mg-containing Zn-coated steel sheets, etc. with water vapor in a closed vessel, which resulted in peeling due to lattice mismatch with the base substrate, According to the example, the problem of peeling can be solved by forming a TiZn 2 compound and ultimately forming a Ti-Zn coating with high lattice matching with a titanium substrate as a base material.
상기 Ti-Zn 피막을 생성시키는 단계는, 1.0 x 10-3 Pa 내지 2.0 x 10-3 Pa의 작업 진공도 및 50W 내지 200W의 DC 파워 조건 하에서 실시할 수 있다. 상기 범위의 작업 진공도를 가질 경우 방출 입자들의 mean free path가 길어지고 모재의 산화를 방지할 수 있어, 티타늄 기판(모재) 및 Ti-Zn 합급층 간 결합력을 향상시킬 수 있고, 상기 범위의 DC 파워를 가질 경우 짧은 시간에 고밀도의 피막을 증착시킬 수 있어 작업시간 소요로 인한 비경제성을 제거할 수 있다.The step of forming the Ti-Zn coating may be performed under a working vacuum of 1.0 x 10-3 Pa to 2.0 x 10-3 Pa and a DC power of 50W to 200W. When the working vacuum degree is in the above range, the mean free path of the emitting particles is increased and the oxidation of the base material can be prevented, so that the bonding force between the titanium substrate (base material) and the Ti-Zn alloy layer can be improved, It is possible to deposit a high-density film in a short time, thereby eliminating the non-economical efficiency due to the operation time.
상기 Ti-Zn 피막을 생성시키는 단계는 건식도금법으로 실시하는 단계일 수 있다.The step of forming the Ti-Zn coating may be carried out by a dry plating method.
예컨대, 상기 건식도금법은 화학적 증착법(CVD; Chemical Vapor Deposition) 또는 물리적 증착법(PVD; Physical Vapor Deposition)일 수 있다.For example, the dry plating method may be a chemical vapor deposition (CVD) method or a physical vapor deposition (PVD) method.
예컨대, 상기 건식도금법을 이용하면, 높은 에너지를 가진 입자들을 Target(Ti, Zn)에 충돌시켜, 상기 목적화하는 원자들이 방출되어 나오면, 이를 기판에 증착시킬 수 있다.For example, when the dry plating method is used, high energy particles collide with a target (Ti, Zn), and when the targeted atoms are emitted, they can be deposited on a substrate.

At this time, the working vacuum degree is 1.5 × 10 -3 Pa and the DC power is 100 W.
