Influence in Lubricant Oxidation in Wear of Metallic Surfaces

The lubricants are certain type of substances that are applied to the contact surfaces of machines to reduce friction among the mobile parts. This friction originates a heating in pieces and wear of superficial layers. This heating produces a bad operation in parts of machines. So, lubricant protects the metallic surfaces against the action of the corrosive agents. The main part of this work consists on determining as the oxidation of lubricant influences in rubbing of the pieces and its relationship with the produced wear and their results are better in operations normal conditions when is compared when the lubricant is oxidized. The lubricant can be natural or synthetic. Among the natural lubricants it is possible to mention organic oils and minerals, fats or graphite. Among synthetic lubricants are silicones and special products able to support very high temperatures as those characteristic of advanced motors diesel. They can be coatings that allow to the mobile parts to be lubricated itself, or oils degraded without produce traces after rubbing.
