持たないと耐食性は得られない。Normally, alloys are crystallized in the solid state, but if a method that does not form long-period regularity in the atomic arrangement in the process of solid formation is applied, such as when the alloy structure is limited to ultra-rapid solidification from the molten state by limiting the alloy structure, the crystal structure is An amorphous structure similar to a liquid can be obtained without such a substance. Such an alloy is called an amorphous alloy. Amorphous alloys are mostly homogeneous single-phase alloys of supersaturated solid solutions, have significantly higher strength than conventional practical metals, and exhibit various properties such as abnormally high corrosion resistance depending on the composition. The present inventors have conducted research to utilize the characteristics of such amorphous alloys, and as a result, have been subject to pitting corrosion, crevice corrosion and general corrosion even in highly corrosive aqueous solutions such as aqueous solutions containing strong acid or high concentration chlorine ions. A high corrosion resistant amorphous nickel-based alloy was found, and was previously filed as Japanese Patent Application No. 51-132290.In addition, a highly corrosion resistant amorphous alloy that can be used in a severe corrosive environment containing boiling concentrated nitric acid or an oxidizer has We applied for a patent as Japanese Patent Application No. 60-51036, and found a highly corrosion-resistant amorphous alloy that can be used in a severe corrosive environment such as boiling concentrated chlorine. We applied for a patent as No. 60-172861. All of these are amorphous nickel alloys. As described above, concentrated phosphoric acid has a high boiling point, so that it is particularly corrosive at high temperatures, and corrosion resistance cannot be obtained unless the alloy itself has the ability to form a stable protective film.

In addition to the alloys described in Nos. 60-51036, 60-172860 and 60-172861, a stable protective film is formed even in a severe corrosive acid with poor oxidizing power such as high temperature concentrated phosphoric acid, resulting in high corrosion resistance. The present invention has been accomplished by finding that an amorphous nickel alloy having the above is obtained.

Therefore, the amorphous nickel alloy of the present invention is formed with a protective film that ensures extremely uniform and high corrosion resistance.

ろ耐食性に有害である。Since metallic materials are easily dissolved in high-temperature concentrated phosphoric acid solution with weak oxidizing power, in order to use metallic materials in such an environment, it is necessary to give metallic materials the ability to form a stable protective film. There is. This is achieved by making an alloy containing the required amount of active elements. However, in the case of a crystalline metal, addition of a large amount of various alloying elements often results in a multiphase structure having different chemical properties, and it may not be possible to achieve a predetermined corrosion resistance. Also, the occurrence of chemical non-uniformity is rather detrimental to corrosion resistance.

Since it contains a required amount of effective elements capable of forming a stable protective film uniformly, such an amorphous nickel alloy forms a uniform protective film and exhibits sufficiently high corrosion resistance.

護皮膜形成を保証するものである。That is, the condition that a metal material that has a weak oxidizing power and withstands concentrated phosphoric acid at high temperature is to have is that it has a high protective film-forming ability that a stable protective film is uniformly formed in a non-oxidizing environment. This is realized by the alloy composition of the present invention, and the fact that the alloy has an amorphous structure makes it possible to prepare an alloy having a complicated composition as a single-phase solid solution and guarantees formation of a uniform protective film.

次に、本発明における各成分組成を限定する理由を述べ
る。Next, the reasons for limiting the composition of each component in the present invention will be described.

Niは本発明合金の基礎となる元素であって、Ｐ、Ｂ、Si
などの半金属をと共存してアモルファス構造を形成する
元素であり、また、耐食性を担うMoおよびCrの作用を助
ける元素である。Ni is an element which is the basis of the alloy of the present invention, and contains P, B and Si.
It is an element that forms an amorphous structure in coexistence with a semi-metal such as, and is an element that assists the actions of Mo and Cr that are responsible for corrosion resistance.

Moでは、高温濃リン酸中で耐食性が不十分であり、また
多量すぎると、アモルファス構造を得るのが困難にな
る。したがって、本発明の第１および第２の発明におい
てMoは10−30原子％とする必要がある。Mo is an element responsible for corrosion resistance by forming a protective film in a non-oxidizing acid such as hot phosphoric acid. But too little
Mo has insufficient corrosion resistance in high-temperature concentrated phosphoric acid, and if it is too much, it becomes difficult to obtain an amorphous structure. Therefore, in the first and second aspects of the present invention, Mo needs to be 10-30 atomic%.

Crは不働態皮膜を形成する元素であって、高温リン酸の

In the third and fourth aspects of the present invention, Mo is set to 15-30 atomic% and Cr is set to 30-40 atomic%.

20原子％とする。As described above, P is an element that is effective not only in coexisting with Ni to form an amorphous structure, but also in promoting formation of a protective film containing Mo and Cr as main components. However, in an acid that is highly corrosive such as high-temperature phosphoric acid, an alloy containing a large amount of P may have a phosphate film with a low protection property that is oxidized by P. Therefore, in the first aspect of the present invention, P is in the range of 15-23 atom%. When the alloy contains a considerable amount of Mo, the amorphous forming ability is improved, so that the amount of P necessary for forming the amorphous structure can be reduced. Therefore, in the third invention of the present invention, P is 8−

がある。B and Si are elements that are effective in coexisting with Ni to form an amorphous structure and can replace P. However, in order not to reduce the action of P that promotes the formation of the protective film, it is not preferable to replace P by more than 7 atomic% in total of one or two of B and Si. Therefore, in the second and fourth inventions of the present invention, the total of one or two of B and Si is 7 atomic% or less, and the total of P and P is 15-23 atomic% in the first invention. In the fourth invention, it is necessary to set it to 8-20 atomic%.
