通常、化学研摩が広く用いられている。In recent years, phosphor bronze alloys have been used in a wide variety of applications, from automobile bearings to turbine blades, as well as spring materials and contact materials, due to their excellent tensile strength. Among these, phosphor bronze parts used as spring materials and contact materials require polishing to remove the particles generated during mechanical processing, and chemical polishing is usually widely used for this purpose. There is.

, Zn 40%), but has no brightening effect on other copper alloys with α-structure, and the bath composition such as the addition of phosphoric acid The problem was that it required conversion.
又、キリンス法では基本成分が硝酸であることによシ有
害ガス（ＮＯｘ ）の発生や局部反応によシ表面が梨地
状になｐやすい、浴寿命が短い等の欠点があった。In addition, the Kirinsu method has disadvantages such as generation of noxious gas (NOx) due to nitric acid as a basic component, a tendency for the surface to become matte due to local reactions, and a short bath life.

An object of the present invention is to provide a chemical polishing solution for phosphor bronze alloys that can be chemically polished.

こシ平滑な金属光沢面が得られない。The chemical polishing solution of the present invention provides extremely effective results when used within the above composition ratio range. If the type of sulfuric acid and nitric acid used is outside the above range, no advantageous polishing effect can be expected, and if the type of hydrochloric acid or nonionic surfactant used is outside the range above, non-uniform reactions may occur. A smooth metallic glossy surface cannot be obtained.

防止できる。According to the above-mentioned experiments based on the present invention, by adding a nonionic surfactant to a chemical polishing solution containing sulfuric acid, nitric acid, and hydrochloric acid, the polishing speed can be easily controlled, and in addition, the generation of harmful gases can be suppressed. It was confirmed that a glossy, smooth and clean surface could be obtained. In other words, the added surfactant lowers the surface tension of the polishing solution and makes it easier to detach from the metal surface, so it is always uniform on the metal surface without causing local reactions that cause overetching or ah. This is thought to be due to the progress of a reaction. In addition, a sufficient polishing effect can be expected without the need for reaction in the air as in the Kirinsu process, thereby preventing the generation of harmful gases.
以下、本発明を実施例に従って説明する。Hereinafter, the present invention will be explained according to examples.
