Metals such as iron, chromium, nickel, and aluminum, or alloys thereof, lose their original performance due to so-called corrosion phenomena, although there are varying degrees of difference. This is caused by oxygen, water, chlorine ions (Ol-), etc. present in the environment in which the material is used coming into contact with the surface of the material. For this reason, various surface treatment methods have been proposed in the past, but none have yet been fully satisfactory. That is, (1) a method of applying an organic coating by conventional painting, electrodeposition coating, or powder coating; (2)
The following methods are known: (3) coating the metal surface with a ceramic coating such as enamel, (3) coating the metal surface by thermal spraying or hot-dip plating, and (4) plating the metal surface with electroplating or chemical plating. However, method (1) has disadvantages such as the coating film deteriorating over time and lack of heat resistance, and method (2) has problems with the impact resistance and thermal shock resistance of the coating. . In addition, the coating obtained by method (3) does not have perfect corrosion resistance and is relatively thick, resulting in a large increase in weight.Method (4) also has the problem of corrosion resistance and increase in weight, and furthermore, the plating waste liquid The disadvantage is that processing is cumbersome.

By mixing or multilayer coating and baking at 100 to 600°C, an amorphous thin film is formed. Coating methods include adjusting the alkoxide solution to the desired concentration and viscosity with a solvent such as alcohol or ester, and then applying it by spraying, spinning, brushing, etc., immersing the metal material in the solution and then pulling it up, or using a roll. -;-tar method etc. can be used.

In the metal material of the present invention, after being coated with the alkoxide, it is baked at a temperature of 100 to 600°C, but an amorphous film cannot be formed at less than 100°C.
On the other hand, if the temperature is higher than 600°C, the amorphous film will crystallize, which is not preferable. It is particularly preferable that the amorphous thin film formed by baking in this manner has a thickness of 100 to 5000 Å. If the film thickness is less than 100λ, the anticorrosion function will not be sufficient, and if it is thicker than 5000A, the adhesion of the film will be poor.

In particular, when the surface of the metal material is mirror-finished, adhesion deteriorates when the surface is 2000 Å or more, but when the surface is roughened, the adhesion is maintained even when the surface is 5000 Å or more. However, from an economic point of view, 5,000

The thickness of the above-mentioned amorphous thin film can be freely controlled by adjusting the coating method, and the baking after coating can be controlled by changing the temperature.
The properties of the surface film can be freely selected depending on the time. For example, when coating a metal material by immersing it in a metal alkoxide solution and then pulling it up, a calibration curve showing the relationship between pulling speed and film thickness is created in advance through experiments, and the desired film thickness is determined from this curve. A desired film thickness can be obtained by pulling up the metal material at a pulling speed that satisfies the desired film thickness.

The metal material of the present invention is covered with a dense, non-conductive amorphous thin film by selecting the metal species contained in the alkoxide.
Water, chlorine ions, etc. are prevented from coming into contact with the metal surface.
At the same time, the corrosion current is so small that virtually no corrosion occurs, and the amorphous thin film is so thin that the significant increase due to coating is minimized. In addition, unlike organic coatings, it does not change over time, so its initial anti-corrosion function is maintained semi-permanently, and even at temperatures of several hundred degrees Celsius...
There is almost no change in quality, and there is no phenomenon such as cracking even if there is a sudden temperature change. In this way, the metal material of the present invention has excellent corrosion resistance and high-temperature corrosion resistance, and since the amorphous layer is a thin film, the metallic luster of the base metal is not lost much, and the metal material has excellent corrosion resistance and high-temperature corrosion resistance. The unique interference color adds to the metallic luster, giving it a unique and pleasing tone. Therefore, the metal material of the present invention is suitable for automobile engine parts, such as injection nozzles, automobile exhaust system parts, such as exhaust tubes, diffusers, kerosene stove parts, such as burner parts, reflectors, combustion cylinder parts, other heating equipment parts, and various other parts. It has a wide range of uses as a material for combustion equipment, etc.
