1.Not familiar with track cogs, but if it is anything like the outermost threaded cog in a regular cassette, it is because the right-hand thread naturally gets tightened by the chain when driven.
2. Galling occurs when two metals in moving contact at high pressure "weld" to each other at certain spots and then tear small chucks of material from each other.
