Abstract
A method for lubricating a material-working tool comprises depositing a material film by high energy level vacuum plating onto the tool for providing a thin mechanically insulating film having a low shear stress value. The material film has a hardness which is less than the hardness of the tool which it overlies.
Claims11
A method for lubricating a material-working tool comprising:
- depositing a first material film layer of nickel-titanium material by high energy level vacuum plating onto the tool, the first material film layer having a hardness less than the hardness of the tool;
- depositing a second material film layer selected from the group consisting of silver-palladium material and gold-palladium material by high energy level vacuum plating onto the first material film layer, the second plating onto the first material film layer, the second material film layer having a hardness less than the hardness of the first material film layer;
- and
- the first and second material film layers providing a thin mechanically insulating film and deposited to a total thickness of about 10,000 angstroms on the tool.

A material-working tool having a core material and an exterior surface comprising:
- a first material film layer of nickel-titanium material deposited by high energy level vacuum plating onto the exterior surface of the tool, said first material film layer having a hardness less than the hardness of the tool core material;
- a second material film layer selected from the group consisting of silver-palladium material and gold-palladium material by high energy level vacuum plating onto said first material film layer, said second material film layer having a hardness less than the hardness of said first material film layer;
- and
- said first and second material film layers deposited to about 10,000 angstroms in total thickness for providing a thin mechanically insulating film on the exterior surface of the tool.
1 more element
A guide for paper handling, the guide having a core material and a surface for contacting paper comprising:
- a first material film layer deposited on the surface of the guide by high energy level vacuum plating, said first material film layer having a hardness which is less than the hardness of the guide core material.
