FRICTION activated ANTI-WEAR COMPONENT
- FRICTION activated ANTI-WEAR COMPONENT:
The friction activated Component, the second line of defense against wear, chemically polishes bearing surfaces on an as needed basis. This phenomenon gives equipment treated with the AircoFridge Optimizer two significant advantages over untreated units. First, the chemical friction is reduced. Second, the Component provides damage control in the event of total lubrication failure. It is important to note that this chemical polishing takes place only where high friction exists.
As stated in the previous section, the contact activated Component forms an extreme pressure barrier on metal surfaces. Under heavy loads, this barrier can be worn away. As this happens, however, the barrier is quickly replaced by the contact Components (which is uniformly distributed in the oil). Under sever operating conditions, such as a rough bearing surfaces or lubrication failures, the protective barrier begins to fail (it wears off faster than it can be replaced). When the moving surfaces come in contact, friction increases and temperatures rise dramatically at the high wear spot. These high temperatures (over 400˚F) weaken internal chemical bonds of the contact activated Component and allow it to transform into the “friction activated” Component. This Component, in turn chemically interacts with the surface atoms of the metal (to which it is bonded), in such a way
as to provide a chemical polishing action. The higher the wear (the higher the temperature), the faster the friction activated Component forms and the quicker the chemical polishing action occurs. When friction is reduced, the Component is stable and chemical polishing stops. The friction-activated Component performs only when and where it is needed. The friction-activated Component can actually eliminate minor bearing defects and rough spots.
