Actually it does. "examination of mid-life OE bearings showed overlay corrosion to be a significant factor influencing bearing wear rate, as shown in Figure 1. Whilst corrosion is largely caused by oil degradation and operating temperature.... "
It's well documented and researched in peer reviewed engineering journals on why lead indium is a better overlay choice than lead / tin / copper.
