Babbitt is pretty standard as the top coating for the main engine bearing. But yes, it has been a very long time since we used pure babbitt bearings. Model T/A peined babbitt I think
>The modern practice (milwaukeebearing.com) for connecting the crankshaft and rod big end bearings (found in modern engines) consists of a replaceable steel shell that is keyed to the bearing caps. The inner surface of the steel shell is then plated with a coating of bronze, which is then coated with a thin layer of babbitt metal that makes up the surface of the bearing. This process is known as babbitting.
