Flexible Manufacturing System - FMS. What is a 'Flexible Manufacturing System - FMS'. A flexible manufacturing system (FMS) is a method for producing goods that is readily adaptable to changes in the product being manufactured, in which machines are able to manufacture parts and in the ability to handle varying levels of production.
When corrosion occurs after the in-process time, the cause may be a corrosive atmosphere. Heat treat departments may exhaust corrosive fumes. One of the most corrosive is sulfur dioxide fumes which will quickly corrode metal surfaces.
The main problems with the higher zinc alloys are dezincification and stress corrosion cracking (SCC). In dezincification, a porous layer of zinc free material is formed locally or in layers on the surface. Dezincification in the high-zinc alloys can occur in a wide variety of acid, neutral and alkaline media. Dezincification can be avoided by maintaining the zinc content below about 15%, and minimized by adding 1% tin such as in Admiralty brass (C44300) and Naval brass (C46400).
