  • Bearing for an internal combustion engine
    Patent number: 9212696
    Abstract: A bearing for an internal combustion engine may include a ferrous base material onto which a primary layer of a bronze alloy is disposed and a deposited layer applied over the primary layer. A bonding layer may be applied onto the primary layer between the primary layer and the deposited layer. The bonding layer may include nickel and chrome, and the deposited layer may include a metal alloy composed of aluminum and tin. A sliding layer may be disposed on the deposited layer and include a polymeric polyamide-imide matrix provided with a soft metal and at least one of a fluoropolymer and a silane-based material. The ferrous base material, the primary layer, the bonding layer, the deposited layer and the sliding layer in combination may be capable of standing a gripping load higher than 85 MPa.
