TUNGSTEN DISULFIDE SURFACE TREATMENT AND METHOD AND APPARATUS FOR ACCOMPLISHING SAME

摘要

A tungsten disulfide metal surface treatment in which the substrate material is prepared by impingement of blast media particle sizes to create pockets in the substrate material approximately matched to the size of the tungsten disulfide particles. A sand blast apparatus (20) having a vibratory bowl (92) with a throttled intake pipe (104) enables the blast media particles to prepare the substrate with the formed pockets. A method for forming the tungsten disulfide surface treatment through roughening of the substrate surface in a controlled manner is disclosed.
