Dry corrosion occurs when the metal reacts with oxygen in the air.

Corrosion will be useful when you work on corrosion industry.
Types of corrosion 1. Induced corrosion due to chloride 2. Pitting 3. Corrosion due to Oxidation 4.Corrosion is due to dissimilar materials 5. Corrosion due to imbalanced electrovalency In Electro-chemical theory,when two materials of different potential are in contact with each other through electrolyte, the two materials become, one is cathode and the other anode. The ions(electrons ) passes from anode deposited on cathode. Protection methods: 1.Metallurgical method 2.Corrosion inhibitors 3 Coatings like paintings, epoxy application etc 4. Cathodic protection 5 Galvanisation 6 Balancing of of electrovalency of materials or reducing impurity 7 use of sacrificial anode

Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?
Usually, corrosion consists of a process called oxidation, which often takes the form of rust. In the case of iron, it occurs when oxygen makes contact with the metal, and the two combine. Corrosion can also occur by other processes, such as with microscopic organisms.

enzyme specificity
Magnetite Layer is developed after essential chemical treatment. For instance, hydrazine and sodium sulfite are the most broadly chemicals. The presence of this layer has as result the deceleration of corrosion attack in tube's surface. Moreover, when this protective layer is spoiled, then mechanism of corrosion is going to start.
A little more info would help.m Do you have tension on the handle? Does the window open. Was there signs of corrosion on the locking mechanism? I would try removing the interior panel to see if you can move the locking mechanism w/ a screw driver. A little more info would help Do you have tension on the handle? Does the window open.

Well... I don't really know :P
