Passivation of stainless steel is another use of this term. This article describes the process, which should be described here.--Joel 20:23, 26 April 2006 (UTC)
[edit] Java Programming Passivation?
Though I'm not qualified to write it, there is a separate meaning of passivation not addressed here. It is essentially this: in the Java Computer Programming language, bits of programming functionality are written in objects called Enterprise Java Beans (EJBs). EJBs can be loaded into the computer's memory to do some work. Over time this fills the computer's memory. In order to conserve memory, the current state (data) of the EJB can be written to a database or file. Once this state information is "backed up" to disk, the computer memory that held the data can be freed up for other use.
In this context, passivation is the process of taking the EJB's state information and moving it to persistent storage ("serializing" it).
I don't know if a disambiguation page is called for, but if you Google "Java passivation" plenty of hits with definitions will come up. Jebbo 14:40, 28 June 2006 (UTC)
[edit] Aluminium does not corrode in salt water
I don't understand the ins and outs of aluminium alloying sufficiently to edit the page, but the section on the need to anodise aluminium in salt water environments is incorrect. Aluminium 5083, and other marine grades (see the article on "Aluminium") do not need to be anodised, and will not corrode in a salt water environment unless brought into direct contact with mild steel, bronze or another material further up the saltwater galvanic table. My understanding is that this is because of the exclusion from marine grade alloys of materials prone to interact galvanically with aluminium, such as copper. Aluminium alloy is an increasingly widespread shipbuilding material and while anodising is sometimes used for window frames, it is not used for hull structure.
Expert input is needed here to correct this section.
