Patent ID: 8663815

Claim:
A vehicular transmission part, comprising an organic polymer composition which is coated at least in part only on its surface by a metal, wherein said organic polymer composition includes a filler and a reinforcing agent, the reinforcement agent being one of a glass fiber and a carbon fiber, wherein said metal coating deposited on the surface of the reinforced organic polymer composition is 0.010 mm to 1.3 mm thick and includes at least two layers including a layer comprising Cu and a layer comprising Ni, at least one layer of said metal coating has an average grain size of 5 nm to 200 nm, wherein an impact energy according to ISO 0179 of a metal coated section of said organic polymer composition is at least 1.5 times an impact energy of an uncoated section of said organic polymer composition, wherein the impact energy of the uncoated section of the organic polymer composition is in the range of 40.7 kJ/m 2 to 90.4 kJ/m 2 , and wherein the transmission part is at least one of a transmission case or other part of an external housing, for manual a transmission or transfer case a transmission fork, shift linkage, gear, gear set, or synchronizer, for an automatic transmission a valve body, torque converter, clutch plate, clutch disk, pump, or gear set, for a continuously variable transmission a drive belt, drive or driven pulley, toroidal disc or roller, a variable displacement pump, or a planetary gear set.
