Abstract
The utility model relates to a nanometer complex alloy eutectic duct piece bolt. The surface of the duct piece bolt body is coated with a zinc-iron-aluminum alloy eutectic layer. The utility model has the advantages that the eutectic layer is integrally uniform with consistent thickness; the eutectic layer has high hardness, strong wear and scratch resistance; the eutectic layer and matrix metal have high bonding strength; the eutectic layer has strong corrosion resistance; the eutectic layer has excellent coating performance and good adhesive strength with various paints and macromolecule coatings; the eutectic layer contains no heavy metal cadmium and is environmental-friendly and free from pollution; and the nanometer complex alloy eutectic duct piece bolt is free of hydrogen brittleness damage, and has low processing temperature, and short processing time, avoiding hydrogen brittleness damage to eutectic layer.
Description
Technical field
The utility model belongs to a kind of bolt, particularly a kind of nanometer multi-component alloy co-cementation section of jurisdiction bolt.
Background technique
The section of jurisdiction bolt is used for the connection between the subway section of jurisdiction.During use, carry out preservative treatment to it.At present, generally the section of jurisdiction bolt of Shi Yonging is at its surface brush lacquer coating mostly, its antiseptic property is relatively poor, need constantly more to bring its normal use of assurance, not only increased engineering cost, the maintenance in later stage brings many inconvenience, more can not satisfy major works 30-50 and be embedded in underground use for a long time, in addition, there is pollution in its production with in using.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide that a kind of antiseptic property is good, technology is simple, cost is low, the nanometer multi-component alloy co-cementation section of jurisdiction bolt of environmental protection.
Technical solution of the present utility model is: a kind of nanometer multi-component alloy co-cementation section of jurisdiction bolt is characterized in that: comprise the section of jurisdiction body of bolt, the surface of the section of jurisdiction body of bolt coats zinc-iron aluminum alloy co-penetration layer.
The thickness of described zinc-iron aluminum alloy co-penetration layer is 20-100 μ m.
Zn, the Fe of described zinc-iron aluminum alloy co-penetration layer, the mass fraction of Al composition are respectively: Fe 10.58%, and Zn 78.42%, and Al 11.0%.
The beneficial effects of the utility model are:
1, the whole homogeneous of section of jurisdiction bolt surface zinc-iron aluminum alloy co-penetration layer, consistency of thickness.
2, co-penetration layer hardness height is wear-resistant strong with the scratch resistance ability.The co-penetration layer micro-penetration hardness is generally 220-420Hv, is the hardest present co-penetration layer.
3, the adhesive strength height of co-penetration layer and parent metal.
4, the co-penetration layer corrosion resistance is strong.Resisting salt fog corrosion experiment reached more than 1000 hours, was limited to 50 years in anticorrosive year, especially was fit to marine atmosphere, abominable multiple environment such as industrial atmosphere, can resist＜1000 ℃ high temperature oxidation and corrosion.
5, the co-penetration layer paintability is good, and has good bond strength between various paint and the polymeric coating material.
6, co-penetration layer does not contain heavy metal cadmium, environmental protection, pollution-free.
7, no hydrogen embrittlement harm, processing temperature is low, the time is short, has avoided co-penetration layer the harm of hydrogen embrittlement to occur.

Fig. 1 is a schematic cross-section of the present utility model.
Embodiment
Embodiment: a kind of nanometer multi-component alloy co-cementation section of jurisdiction bolt, comprise the section of jurisdiction body of bolt 1, the surface of the section of jurisdiction body of bolt coats zinc-iron aluminum alloy co-penetration layer 2, and section of jurisdiction bolt surface zinc-iron aluminum alloy co-penetration layer is the form of whole homogeneous, consistency of thickness, and the thickness of zinc-iron aluminum alloy co-penetration layer is 80 μ m; Through the SEM line scanning along thickness direction, the Zn of co-penetration layer, Fe, Al composition are more even, and the mass fraction of each composition is respectively: Fe 10.58%, and Zn 78.42%, and Al 11.0%.
The utility model adopts in No. 2 lines of Tianjin Underground and No. 3 line shield structure intervals.Hardness height, co-penetration layer abrasion resistance properties are good more, and anti-surface tear ability is strong; Co-penetration layer is difficult to peel off for the diffusion metallurgy combination, has only with chemical method and just can remove.Co-penetration layer and parent material interface tensile strength: 600-700Mpa; The surface layer tensile strength is: 300-350Mpa.
Open and the technique scheme that proposes of the utility model, those skilled in the art can be by using for reference this paper content, and links such as its structure of appropriate change realize.Technology of the present utility model is described by preferred embodiment, person skilled obviously can be changed or suitably change and combination the techniques described herein in not breaking away from the utility model content, spirit and scope, realizes the utility model technology.Special needs to be pointed out is, the replacement that all are similar and change apparent to those skilled in the artly, they are regarded as being included in the utility model spirit, scope and the content.
