COULOMB FRICTIONAL DAMPING COATED PRODUCT
One variation may include a method of making frictional surfaces for products having coulomb friction damping are provided. The method may include coating a metallic member with a coating including friction material. The metallic member may be pressure rolled to achieve a desired coating thickness and or the metallic member may be micro-waved to cure the coating.
1 . A method of manufacturing a product with a coulomb damping surface comprising:
coating a metallic member with a material including friction materials; and
curing said coating comprising exposing the material microwave energy.
2 . A method as described in claim 1 wherein the material further comprising mixing a binder with said coating.
3 . A method as described in claim 1 further comprising exposing said coating to at least one of radiant energy or convection energy.
4 . A method as described in claim 1 wherein said coating comprises at least one of spraying, dipping, injecting or covering said product with said material and wherein said material comprises a fluid, powder or paste.
5 . A method of manufacturing a product with a coulomb damping surface comprising:
coating a metallic member with a matter including friction materials to provide a coated member;
pressure rolling said coated member to provide a desired thickness of said material on said metallic member.
6 . A method as described in claim 5 further comprising curing said material comprising exposing the material to microwave energy.
7 . A method as described in claim 5 wherein said rolling said coated member comprising moving rollers along opposite sides of said coated member.
8 . A method as described in claim 7 wherein said coated member is rolled along a generally horizontal path.
9 . A method as described in claim 7 wherein said coated member is roiled along a generally vertical path.
10 . A method as described in claim 5 further comprising mixing a binder with said friction materials.
11 . A method as described in claim 5 wherein a roller utilized for pressure rolling said coated member comprises providing adjustment in position, rotational speed, or force placed thereon to compensate for at least one of a group properties of said metallic member, an environment of said metallic member, or coating, including a force of weight of said metallic member, a viscosity of said coating, a temperature of said coating or said metallic member, a humidity of an atmosphere surrounding said metallic member, a desired thickness of said coating, a differential in a desired thickness of coating versus a thickness of coating sensed of a currently rolled metallic member or a prior rolled metallic member, a sequence of coating of a multiple coated metallic member, a function dependent upon a relationship of a linear displacement or derivatives thereof of the metallic member versus linear displacement or derivatives thereof of a surface of a roller utilized to pressure roll said metallic member.
12 . A method as described in claim 11 wherein said adjustment is automatic.
13 . A method as described in claim 5 wherein the coating comprises at least one of spraying, dipping, injecting or covering said product with a fluid, powder or paste of said coating.
14 . A manufactured product with a coulomb damping surface comprising:
a metallic member comprising a coating thereon comprising friction materials; and
wherein said coating has a substantially uniform thickness free of cracks and bubbles.
15 . A product as described in claim 13 wherein said coating includes a binder.
16 . A product as described in claim 15 wherein said coating the binder comprises at least one of epoxy resins, phosphoric acid binding agents, calcium aluminates, sodium silicates, wood flour, clays or mixtures thereof.
17 . A product as described in claim 14 wherein said friction materials comprises at least one of silica, alumina, graphite with clay, silicon carbide, silicon nitride, cordierite (magnesium-iron-aluminum silicate), mullite (aluminum silicate), zirconia (zirconium oxide), phyllosilicates, non-refractory polymeric materials, ceramics, composites, wood or mixtures thereof.
