特性を維持することができなくなつた。 Conventionally, tape guide members such as capstans used in audio and video equipment have been treated by mechanical methods such as sandblasting, liquid honing, and ceramic coating, or by chemical methods such as etching. Mechanical methods are easy to operate, but problems arise in maintaining a constant surface roughness and in keeping the roundness below 0.5 μm, which is considered not to cause distortion in the sound. As for the etching method, which is a chemical method, it is known that a ferric chloride solution is used as an etching solution. When the material was etched to a certain extent, the intergranular corrosion of the material was severe, and rust easily occurred in the salt spray test (JIS-Z2301). In addition, when assembled into a tape recorder and used, the tape could be driven stably at the beginning of use, but as the usage time increases, the surface roughness changes due to friction with the tape and the initial characteristics are maintained. I couldn't do it anymore.
そこで、この発明は、従来技術に係る諸欠点を

液として好適なものとなる。 Examples of the compound used as a cupric ion source include cupric halides such as cupric chloride and cupric bromide, copper sulfate, and cupric nitrate. The amount of such compound used is not particularly limited, but is conveniently about 0.5 to 200 g/g. If too little of such compounds is used,
Etching takes too much time, and if it is too much, the etching time is too short and there is a risk that a uniform surface roughness will not be obtained, as well as precipitates as the mineral acid concentration and temperature decrease. This is not desirable in practice. When these compounds are made into an aqueous solution, they generate cupric ions and are suitable as the etching solution used in the present invention.

硝酸などが挙げられる。この鉱酸は約0.1〜６規

Examples include nitric acid. This mineral acid is preferably used in a range of about 0.1 to 6N.

ある。 The etching agent that can be used in this invention in which cupric ions are present as described above may optionally contain a surfactant to lower the surface tension of the treatment solution and a surfactant to further suppress intergranular corrosion. Alcohols such as ethanol, and additives such as carboxymethyl cellulose and carboxyethyl cellulose as viscosity modifiers can be added. When using alcohols, the amount is preferably up to about 40% by volume, and the amount of surfactants and viscosity modifiers is about 40% by volume.
Conveniently, it is used in a range of 0.01 to 1 g/g.

般的には約10秒間〜20分間であればよい。 Among the etching treatment conditions in the method according to the present invention, the etching temperature is not particularly limited, but is preferably within the range of about 10°C to 70°C. From the viewpoint of practicality such as work, a temperature range of 20°C to 50°C is more preferable. Furthermore, the etching treatment time is not particularly limited, and can be determined as appropriate depending on the degree of surface roughness caused by etching, but in general, it is approximately 10 seconds to 20 minutes. good.

ことができる。 According to the method according to the invention, the tape guide member treated as described above has good roundness and stable surface roughness. Furthermore, grain boundary corrosion is significantly less than when treated with an etching agent containing ferric chloride as a main component, and good results can be obtained in the salt spray test. Furthermore, when the tape guide member processed according to the present invention is assembled into a tape recorder to drive the tape,
Its initial characteristics can be maintained even after continuous running for a long time.
以下、この発明を実施例によつて詳説する。 Hereinafter, this invention will be explained in detail with reference to Examples.
