Abstract: Methods and apparatus are provided for assembling a flange joint for use in a driveline. In an exemplary embodiment the apparatus includes a first flange with a first recess. A second flange may be configured to join with the first flange for translating rotational motion between the first flange and the second flange, the second flange having a second recess corresponding in position to the first recess in the first flange. A shear force member may have a first part configured to contact the first recess and a second part opposite the first part configured to contact the second recess, the second part may have an inclined surface. Multiple fasteners may connect the first flange to the second flange such that the inclined surface of the shear force member is held in contact with the second recess.

Abstract: A method of forming a low-friction coating on a metal substrate includes ferritic nitrocarburizing the metal substrate to form a surface of the metal substrate, wherein the surface includes a compound zone and a diffusion zone disposed subjacent to the compound zone. After ferritic nitrocarburizing, the method includes oxidizing the compound zone to form a porous portion defining a plurality of pores, and, after oxidizing, coating the porous portion with polytetrafluoroethylene. The method further includes, after coating, curing the polytetrafluoroethylene to thereby form the low-friction coating. A low-friction coating system includes the metal substrate having the surface including the compound zone and the diffusion zone disposed subjacent said compound zone, wherein said compound zone includes the porous portion defining the pores, and a cured film formed from polytetrafluoroethylene disposed sufficiently on the porous portion so as to at least partially fill at least one of the plurality of pores.
