た強度と耐蝕性を自在に得ることが難しい。In other words, galvanized steel materials tend to attract microorganisms in seawater;
Short service life. Polymer materials such as nylon are suitable for aquaculture nets due to their flexibility, but are unsuitable as structural materials. In addition, ordinary steel materials are subject to severe corrosion and are not suitable for use in seawater or coastal areas. Furthermore, as the content of Ni as a constituent element increases, the corrosion resistance of Cuproninkel material improves, but it becomes difficult to manufacture, the cost performance decreases, and it is difficult to freely obtain strength and corrosion resistance suitable for various uses.
本発明は上記従来技術の持つ種々の欠点を克服し、海水

〔作用〕
本発明においてＺｎ−Ｎｉ合金被覆層を母材表面に設け
た理由はＺｎ−Ｎｉ合金は極めて優れた耐食性を有し同
時に微生物が付着し難く、耐摩耗性も良好であるからで
ある．
そしてその効果はＺｎ−Ｎｉ合金においてＮｉ５〜３０
ｗ ｔ９Ａ残部Ｚｎであるとき最も著しく、Ｎｉが５ｗ
ｔ％未溝のものでは耐食性が充分でなくまたＮｉが３０
ｗｔ％を超えるものでは製造が困難でありまた耐食性も
飽和乃至は劣化するからである。This material is suitable for use in seawater or in solutions with high (1-1) concentrations and for structures in coastal areas. [Function] In the present invention, a Zn-Ni alloy coating layer is applied to the surface of the base material The reason for this is that the Zn-Ni alloy has extremely excellent corrosion resistance, is difficult for microorganisms to adhere to it, and has good wear resistance.
w t9A The balance is Zn, most significantly when Ni is 5w
t% non-grooved ones do not have sufficient corrosion resistance, and the Ni content is 30%.
This is because if it exceeds wt%, it is difficult to manufacture and the corrosion resistance is saturated or deteriorated.
Ｚｎ−Ｎｉ合金被覆層の厚さは０．５〜３０−であるこ
とが望ましいがこれは０．５μ未満では耐食性向上の効
果が乏し＜３０μを超えるとコスト高となる割合には耐
食性が向上しないからである。The thickness of the Zn-Ni alloy coating layer is preferably 0.5 to 30-30 mm, but if it is less than 0.5 μm, the effect of improving corrosion resistance is poor, and if it exceeds <30 μm, the corrosion resistance will be improved at a rate that increases the cost. Because they don't.
Ｚｎ−Ｎｉ合金被覆層と母材とは拡散結合していること
が被覆層と母材とを強固に結合させるために不可欠であ
るが、この拡散結合の層は同時に耐食性をも向上させる
ものである。Diffusion bonding between the Zn-Ni alloy coating layer and the base material is essential for strongly bonding the coating layer and the base material, but this diffusion bonding layer also improves corrosion resistance. be.
この拡散結合層の厚さは製造条件及び用途により変化す
るが０．１〜３０μｍのときはその特性が優れている。The thickness of this diffusion bonding layer varies depending on manufacturing conditions and uses, but when it is 0.1 to 30 μm, its properties are excellent.
０．１ｎ未満では被覆層と母材との結合力が弱＜ ３０
ｔｍを超えると製造上コスト高となり更には、全体の強
度低下を招くからである。If it is less than 0.1n, the bonding force between the coating layer and the base material is weak < 30
This is because if it exceeds tm, manufacturing costs will increase and furthermore, the overall strength will decrease.
