zero g: dry film lubrication

Zero G - is a wear-resistant, dry film, low-friction boundary lubricant. It supplements fluid lubricant capability by providing a buffer against metal-to-metal contact, and thereby greatly reducing the chance of galling between surfaces in relative motions. The film has a coefficient of friction of 0.030 Vs 0.074 for graphite.

Zero G - is a unique entry into the field of dry film lubrication. It represents a complete departure from the presently accepted concepts of solid-film lubrication. Though boundary lubrication has been practiced for years, its use has been somewhat restricted due to the limited caracteristics of available materials and techniques under conditions of critical load and environment.

Zero G - overcomes many of the problems associated with critical environments. It approaches the ultimate in the field of boundary lubricants due to its high load-bearing capabilities and its low coefficient of friction. Its lubricity exceeds that of other dry lubricants.

Zero G - forms a film-like mono-layer of sub-micron sized, particulate, non-overlapping platelets, which, although they will not adhere to one another molecularly bonds to a mechanically clean metal substrate. Thus particle size, which ordinarily is kept below 0.000020 (millionths) of an inch, determines the thickness of the coating. The film can be applied to all of the metals in common engineering use and also to most of the more exotic types.

Zero G - coating has coefficient of friction that is virtually constant throughout the range from -350F to +1000F ambient, and can lubricate at 2400F in a vacuum of 10-14 Torr. It is essentially stable. Testing at elevated temperatures in higher vacuums indicate it to be extremely stable.

Zero G - particles adhere firmly to the substrate and have no tendency to migrate from the area of highest pressure. The coating is effective as a boundary lubricant in both dynamic and static applications. The load carrying capacity of the coating itself is in excess of 350,000 PSI, at which figure it still retains its lubricity.

Zero G - once applied to a substrate the molecular bond can only be removed by heavy abrasion or shearing of the substrate upon which it resides. It can extend the effective life of virtually any surface to which it can be applied; the life extension depends on the surface quality and the load-bearing capability of the substrate.

Zero G - cannot cause hydrogen embrittlement or work-hardening of the substrate. No bake-out or heat-curing is required, therefore, there is no relief or introduction of stress in the substrate. No resins or binders are used to adhere it to the substrate surface.

Zero G - is inert, non-toxic, non-magnetic, vacuum stable, non-corrosive and offers corrosion resistance. It has been approved for medical and food contact applications.
