  • Dual layer sintered metallic clutch friction facing
    Patent number: 10422390
    Abstract: A method for forming a friction facing comprises placing a bonding powder mix in to a die, and placing a performance powder mix in to the die. Pressing the performance powder mix and the bonding powder mix creates a compact. Sintering the compact forms a friction facing. A clutch disc assembly can be formed. A clutch disc can comprise a mounting hole for securing a friction facing and a backer plate can comprise a pass-through hole. A mounting mechanism joins the mounting hole to the pass-through hole. The mounting mechanism comprises a head-height for a portion of the mounting mechanism that is mounted near the sintered compact. The bonding layer comprises a thickness corresponding to the head-height of the mounting mechanism.
