The potential of new processing routes in Al-based plain journal bearings.

Aluminium-tin alloy linings are used in modern plain journal bearings applications because they offer an acceptable balance between load-bearing capacity and fatigue resistance, in combination with conformability and embeddability. Conventionally processed bearings constitute tri-layer systems whose fatigue performance was found to be strongly dependent on relative layer properties and the micromechanics of hte Al -ling. Novel distributions in the alloy lining and also opened up possibilities for varying mechanical properties through the lining thickness. The paper provides an overview of potential advantages tha HVOF processing routes and new alloying possibilities might offer compared to conventional roll-bonding approaches.
