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