Correct name for corrosion transfer between more/less noble metal, &/ expansion?
I help out a local bike project, and will be restoring this 1994 Marin Sausalito. The main technician said to first to check if the steering-quil-post and seat-post could move, and they did; but because the seat-post is aluminium and the frame is steel, also said to put grease in there - which have also done, but ... -, as now it's been opened after sitting outside for a long time, it may expand as corrosion transfers from a less to a more noble metal (other than the steel rusting), but he couldn't remember the exact sequence. What is he refering to, and how does that work?
