Abstract: A method of making a multi-layer plain bearing comprises roll-bonding a relatively soft aluminum-tin alloy to a harder aluminum-based bearing substrate and then roll-bonding the composite to a steel backing. Following heat treatment conventional for reticulation of the aluminum-tin alloy the surface is machined to give a precise overall bearing thickness of which the aluminum-tin overlay is in the range of 0.01-0.10 mm, typical of an overlay but having greater fatigue strength and war resistance than conventional electro-deposited materials. Alternatively, the overlay substrate and backing strips may be roll-bonded simultaneously.
