命を短かくするケースが生ずる。Industrial chrome plating (hereinafter referred to as chrome plating) is
By plating on the surface of a relatively inexpensive steel material, it is possible to change the surface to a material composition with wear resistance. Defects penetrating the base material such as cracks are unavoidable, and depending on the usage environment, the base material may rust and shorten the life of the component.
そこで、従来、クロムめっきの防食手段として、下地に
Ｃｕめっき、Ｎｉめっきなど施工する方法やクロムめっ
き自体を厚くする厚めつき及び多層めっきが行われてい
る。Therefore, conventional methods for preventing corrosion of chromium plating include applying Cu plating, Ni plating, etc. to the base, thick plating and multilayer plating in which the chromium plating itself is thickened.
しかしながら、下地に他のめっきを施工する方法は、価
格及びクロムめっきの応力により特別の工夫を要し、ま
た厚めつき、多層めっきは十分に安定した効果があると
はいえない事実がある。However, the method of applying other plating on the base requires special measures due to the cost and stress of chrome plating, and the fact is that thick plating and multilayer plating cannot be said to have a sufficiently stable effect.
本発明はこのような事情に鑑みて提案されたもので、防

工程とよりなることを特徴とする。To this end, in order to prevent base metal corrosion through pinholes and cracks that are inevitable in chrome plating, the present invention includes a first step of heating the surface until it reaches the base metal, and then vacuuming the heated base metal surface. The second step is vacuuming and cooling the above surface with a cooling roller after vacuuming.
The third step is to apply sealant to the above surface using a sealant supply roller.
It is characterized by a process.
このような構成により、加熱−冷却により母材の欠陥を

得ることができる。With this structure, defects in the base metal are opened by heating and cooling, air and other gases within the defects are removed, and a sealant is introduced into the defects to increase the anti-corrosion effect and create long-life chrome plating. It is possible to obtain a method for sealing defects in chrome plating that can be applied.
本発明の一実施例を図面について説明すると、第１図は
その側面図である。An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view thereof.
上図において、母材１上に施工されたクロムめっき層２
には欠陥が存在する。In the above figure, chrome plating layer 2 is applied on base material 1.
has flaws.
そこで、第１工程として、この表面を加熱装置３で母材
まで昇温させる。Therefore, as a first step, the temperature of this surface is raised to the base material using the heating device 3.
次に、第２工程としてこれに真空容器４を設置し、十分
排気を行う。Next, as a second step, a vacuum container 4 is installed therein, and sufficient evacuation is performed.
さらに、第３工程として冷却ローラー７及び封止剤１゛
（（給ローラー８を移動アーム６で移動させる。Furthermore, as a third step, the cooling roller 7 and the sealant 1'' are moved by the moving arm 6.
そうすると、加熱状態のクロムめっき層は冷却され収縮
し、これにより、開口した亀裂９が生じ、この直後に封
止剤１０が移動して来るので、亀裂９に封止剤が導入さ
れる。Then, the heated chromium plating layer cools and contracts, thereby creating an open crack 9. Immediately after this, the sealant 10 moves, so that the sealant is introduced into the crack 9.
このような前処理ののちに、クロムめっきを施工すると
、欠陥中の気体は排除され欠陥は封止剤により充填され
ているので、欠陥のない長寿命のクロムめっきを行うこ
とができる。When chromium plating is performed after such pretreatment, the gas in the defects is eliminated and the defects are filled with a sealant, so that chromium plating can be performed with no defects and a long life.

なものである。In short, according to the present invention, in preventing base metal corrosion phenomena through pinholes and cracks that are inevitable in chrome plating,
A first step of heating the surface until it reaches the base material, a second step of vacuuming the heated base material surface, and a second step of vacuuming and/or cooling the surface with a cooling roller after vacuuming. By comprising the third step of applying a sealant to the surface with a sealant supply roller, a method for sealing defects in chrome plating is obtained, which can enhance the anticorrosion effect and provide long-life chrome plating. The present invention is extremely useful industrially.
