BACKGROUND ART Modifying the surface of the structural member from the conventional thermal spray processing technique is used. As the thermal sprayed material, are excellent in various physical properties of the thermal spray coating, zinc or aluminium, or an alloy material based on the obtained material is widely used. For example, Japanese Patent Application JP-2007-138282 (patent document 1) is, 13-78% mass % aluminum, 1-5% containing calcium, aluminum and calcium and the total amount of 79% or less, the balance being magnesium and incidental impurities, the time of thermal spraying and thermal spray explosion-proof and superior in corrosion resistance of magnesium alloy thermal spray technologies relating to disclosed. In addition, the publication JP-2005-179707 (patent document 2) is, containing 5-20 weight % tin, the balance being aluminum and unavoidable impurities, a mixture of the lysed tissue tissue failed to dissolve in the aluminum-sprayed sliding material disclosed technology regarding. In particular, the anticorrosive treatment of the steel, magnesium is added to the aluminum alloy thermal spraying has been so as to be used. However, the magnesium additive to increase the concentration of the corrosion protection will increase and, on the other hand, wear of the thermal spray coating becomes large and persistence of the long-term corrosion performance may not be easily, have been found to be a trade-off relationship (for example, takaya yasuyuki, outside 4 name, 'corrosive properties on Al-Mg alloy of the thermal spray coating mg addition amount effect', thermal spraying, the japan society of thermal sprays, July 2014, the first 51 winding, the first 3 signal, p.82-87: see non-patent document 1). On the other hand, a steel infrastructure Japan, sea salt particles strike it at high temperature and high humidity in the region where the corrosion due to salt significantly degraded, maintenance and management of the point is significant challenges. In order to repair the damage in the case where the deterioration due to corrosion of the steel, after repairing the durability of the importance from the viewpoint of life cycle costs (LCC) is necessary so repaired. However, a typical thermal spray materials zinc - aluminum alloy thermal spray a life span of 60 years and is under a severe environment and is, how to display the target of which is defined by a country road infrastructure and transport bridge does not satisfy the 100 year period. Then, the current metal spray material, the sacrificial anticorrosive brine solubility both that are not found in the spray material may be excellent. |
