Definitions
- the invention relates to an additive composition for use as a metal working fluid or corrosion protection oil and a process for the protection of metals, particularly zinc or aluminum alloys, against corrosion or oxidative degradation.
- Additives which have the purpose to protect metals against corrosion are commonly divided in to two classes:
- Metal deactivators are used to protect yellow metals or alloys, such as copper or brass, and display their protective action in functional liquids, such as mineral oil or fuels, by deactivating the metal ions contained therein. These metal ions can have catalytic effects in undesired oxidative decomposition processes of mineral oil or fuels.
- the protective action is explained by the formation of film-like layers on the surface of metals or by complex formation with metal ions.
- Corrosion inhibitors are primary used to protect ferrous metals such as iron or steel. Analogue to metal deactivators, corrosion inhibitors, are forming also film-like layers on the surface of metals. In addition some corrosion inhibitors can prevent the corrosion, by emulsifying water and minimizing therefore the direct contact of water with the metal surface.
- metal protection methods focus primarily on iron and copper surfaces.
- other metals such as zinc and aluminum and their related alloys, have become very important in many technical applications.
- Zinc and aluminum are, for example, widely used in the manufacture of automobiles. Zinc is widely used as corrosion protection coating of steels, e.g. zinc coated steel coils. Corrosion problems often occur during transport, handling and working of semi-finished metal products. Unfortunately, presently used metal deactivator compositions are less satisfactory or even unsatisfactory to protect these metal surfaces. Therefore, there is a clear need for improved metal working fluids to prevent corrosion of these metals
