Abstract
Abstract Porous wear facings formed of a nodular plated metallic coating are useful as friction elements in wet clutches and the like. The wear and friction characteristics of the wear elements may be further modified for particular applications by coating with phenolic resins, optionally including wear particles.

Independent Claim
33 words
A torque transmitting element adapted for use in a clutch comprising a rigid backing member and a wear facing affixed to said backing member, said wear facing comprising a nodular plated metallic coating.
Claim 2
Dependent Claim
33 words
A torque transmitting element adapted for use in a clutch comprising a rigid backing member and a wear facing affixed to said backing member, said wear facing comprising a nodular plated metallic coating.
Claim 3
Dependent Claim
18 words
The element of claim 1, wherein said nodular plated metallic coating is further coated with a phenolic resin.
Claim 4
Dependent Claim
17 words
The element of claim 1 or 2, wherein said nodular plated metallic coating is formed of copper.
Claim 5
Dependent Claim
22 words
The element of claim 1, wherein said nodular plated metallic coating is formed of copper and further coated by plating with bronze.
Claim 6
Dependent Claim
25 words
5 . -The element of any of claims 1 to 4 wherein said, nodularized metallic coating is plated on a surface of said backing member.
Claim 7
Independent Claim
97 words
A method of producing a wear facing for friction elements comprising a nodular plated metallic coating the method comprising the steps of plating copper dendrites on a metallic substrate, overplating said copper dendrites with a metal selected from the group consisting of copper and bronze, pressing the plated, copper dendrites at a pressure of from 200 psi to 10,000 psi (about 1.37 M Pa to 68.7 M Pa), and repeating the plating, overplating and pressing steps to provide a nodular plated metallic coating having a thickness of from 0.01 to 0.05 inches (about 0.25 to 1.27 mm).
Claim 8
Independent Claim
97 words
A method of producing a wear facing for friction elements comprising a nodular plated metallic coating the method comprising the steps of plating copper dendrites on a metallic substrate, overplating said copper dendrites with a metal selected from the group consisting of copper and bronze, pressing the plated, copper dendrites at a pressure of from 200 psi to 10,000 psi (about 1.37 M Pa to 68.7 M Pa), and repeating the plating, overplating and pressing steps to provide a nodular plated metallic coating having a thickness of from 0.01 to 0.05 inches (about 0.25 to 1.27 mm).
Claim 9
Dependent Claim
92 words
A wear facing for friction elements comprising a nodular plated metallic coating formed by the steps of plating copper dendrites on a metallic substrate, overplating said copper dendrites with a metal selected from the group consisting of copper and bronze, pressing the plated copper dendrites at a pressure of from 200 psi to 10,000 psi (about 1.37 M Pa to 68.7 M Pa), and repeating the plating, overplating and pressing steps to provide a nodular plated metallic coating having a thickness of from 0.01 to 0.05 inches (about 0.25 to 1.27 mm).
Claim 10
Dependent Claim
92 words
A wear facing for friction elements comprising a nodular plated metallic coating formed by the steps of plating copper dendrites on a metallic substrate, overplating said copper dendrites with a metal selected from the group consisting of copper and bronze, pressing the plated copper dendrites at a pressure of from 200 psi to 10,000 psi (about 1.37 M Pa to 68.7 M Pa), and repeating the plating, overplating and pressing steps to provide a nodular plated metallic coating having a thickness of from 0.01 to 0.05 inches (about 0.25 to 1.27 mm).
Claim 11
Dependent Claim
18 words
The element of claim 7 wherein said nodular plated metallic coating is further coated with a phenolic resin.
