Nanotechnology for Horology

The principles of augmenting a lubricant for horological applications have many different good reasons. Due to the demands imposed upon clock oils by virtue of the sheer lack of lubricant quantity, the continual exposure to the drying and oxidizing effects of the open air that the lubricants operate in, eventual failure is an inevitability.

Augmentation of a lubricant by incorporating nanotechnology has nothing but a positive impact on it's performance.

Suspended nanoparticles of tungsten function in a similar fashion to the well - known "moly" additives and graphite used in the past. The scale of the tungsten particles renders them non abrasive and tungsten does not change the metallurgy of the base metals at all. The size of nanoparticles makes the dramatic difference in their ability to actually react on a molecular level compared to moly and graphite.

Nanoparticles have a greater surface area to volume ratio than larger, conventional bits of matter. This allows for more interaction with the metals and the lubricants present.

Surfaces treated with tungsten particles present with less friction under load than ones only exposed to standard lubricants. Clock oils and grease serve not only as lubricants, but when augmented by tungsten nanospheres, serve as a vehicle to transport the tungsten component anywhere friction occurs.

Even when the carrier lubricant fails to function as a lubricant due to oxidation, the tungsten component will still provide lubrication.

The tungsten particles, once exposed to a friction surface, benefit it until it is mechanically abraded away. The pressures endured by horological lubricants do not remove the tungsten component. The tungsten component is rated at 330000 psi.

The quality lubricants used with tungsten nanospheres have a proven record of performance . Adding the tungsten component does not affect the lubricant, just how the friction surfaces interact with each other.

This effect is observed by observing balance action, pendulum motion, noting the "feel" when winding, strike and chime speed, end motion of the different shafts of the movement.

All of these tangible indicators will be noticeably different after exposure to the tungsten component.

Wear is greatly reduced and all aspects of the machines performance are improved.
