The Enviro-Save Metal Treatment process comprises the impregnation of all friction
surfaces with TETRA FLUORETHYLENE (TFE) resin to minimize friction/drag, wear, and corrosion.
Figures 1 and 2 show the top and cross sectional surface views of an engine crankshaft
bearing shell under 4,500 times magnification. This view consists of peaks and valleys, not the smooth polished
surfaces we see with the naked eye. The roughness of the asperity (roughness, unevenness of a surface) induces
turbulence in the oil film between the bearing surfaces and in the boundary (marginal) lubrication mode. This
turbulence encourages oil film breakdown, allowing the bearing surfaces to contact each other.
Figure 3 shows the same bearing surfaces now filled with TFE resin (in green) to the
height of the peaks (only), thus not laying a film or coating which would reduce running clearance, but forming an
impregnation. Subsequent (periodic) monitoring by oil analysis confirms that the single Enviro-Save TFE treatment
remains in the bearing surface indefinitely, without repeat applications.
With the peaks and valleys changed to a smooth plane of TFE resin, oil film breakdown by
asperity induced turbulence is greatly reduced in the boundary lubrication mode, and in the dry start and extreme
adverse modes (loss of oil pressure/lubrication source) where the surfaces touch, damage is minimized when only the
peaks of the asperity may touch. The bearing/load pressure is now taken by the resin-to-resin filled surfaces,
which have the lowest coefficient of friction known. (See Guinness Book of World Records, 1994, page
75).
The TFE impregnation is inert and will provide long term corrosion protection of all
relative engine/equipment components.
