Industrial Mechanics Wear

Wear in any material evidence of an effect of wear is nothing that the release of particulate material by some kind of agents that can have any number of sources. In the case of metals it can be said that most cases wear occurs primarily for two reasons corrosion and friction. Corrosion that develops in metals as these have to go back au natural state, which is in the form of oxide, so it can be said that the effort to avoid it is almost against "nature", according to this fact, therefore, the only thing you can do is minimize the effects of it. Usually we hear the expression "has been or is rusting" in reality is not entirely accurate, but it reflects the above, the metal is forming oxides, the phenomenon is of such magnitude that organizations approach it as one of its main tasks maintenance and represents a very important item in the cost of this activity. In general, we can say that, given by migration of electrons from an element called the anode, which is oxidized to another called cathode is reduced, so that this phenomenon is always necessary verified the presence of three components, the anode or cathode and electrolyte conduction through this is the more common, is corrosion and corrosion variants partial pressures and salt corrosion activity differently. The means to prevent it or avoid it are numerous and may involve actions ranging from the very design of the metal, its geometry, material type surface hardness, etc to the application of the same armor, it is interesting to note that the most used, is, the same oxide layer that forms immediately to the bare surfaces, confining the moisture to the outside of it, as is the case of sodium oxide coating that forms in the material immediately after cutting, or opaque roof that appears on copper after machining, it is of stainless steel oxide chromium and nickel, which are very sticky which gives it protection from friction can say that occurs primarily by lack of lubrication or by having a very poor, since no lubricant vast place, but must be the appropriate, therefore identify two possibilities, hydrodynamic lubrication is that which flows between the components and has a direct relationship with the speed of this flow generating a film of 5 microns and Elastohydrodynamic which has a thickness of 2 microns and has to UNTOC do with the lubricant, the first is fast-moving items, and the second those who have high pressures and low speeds, what is required in both cases is to avoid micro-welding at the points of cash.
