LEAD AND TIN BASED ENGINE BEARING OVERLAYS

indium (9-12.5%) or dispersed alumina particles (0.5-2%). Pb10Sn2Cu and Pb10Sn3Cu compositions are the most popular Pb-based overlay alloys. Hardness of lead based overlay materials is in the range 8-20 HV depending on the content of the hardening component. Fatigue strength of the lead based overlays is about 7250-10150 psi (50-70 MPa).

Tech Update: Which Bearing Is Best For You? Performance ...

Feb 01, 2021  Lead-indium overlay, by contrast, does not need a nickel barrier since there is no tin to migrate. The indium allows for more conformability, bedability, and higher fatigue resistance. This type of bearing is used in higher-end performance applications, but it does not yield as long a service life as copper, tin, lead overlay bearings.

The corrosion of overlay bearings Emerald Insight

AN OVERLAY bearing is a bearing with a precision electroplated overlay of lead‐tin or lead‐indium alloy, 20 to 40µ thick. This lead‐alloy overlay is generally applied to a copper‐lead or lead‐bronze substrate, which is itself bonded to a steel backing. Bearings of this construction are probably the most extensively used type of engine bearings; many millions are manufactured annually.

Electroplated Overlays for Crankshaft Bearings Journal ...

The principal differences between the two overlays lie in their respective fatigue and wear properties. Thus, lead-indium has a higher fatigue strength but lower wear resistance than lead-tin-copper. This paper compares these two major overlays and considers the selection criteria for the overlay employed.

The lead phase in such bearings is readily attacked by weak organic acids and almost all the lead can be leached out unless preventive measures are employed. However, the lead may be protected by an overlay of a lead–tin or lead– indium alloy . 13 About 3% tin or 5% indium in lead will render the lead resistant to attack by oil-oxidation acids.
