Friction's receipt — proof two surfaces disagreed and one lost skin.
means A patch of skin or surface worn away or torn by scraping or rubbing — a scrape, in plainer words.
from From Latin abradere, 'to scrape off' — ab- ('away') plus radere ('to scrape, shave'). The same radere root gives us 'raze' and 'razor,' so an abrasion is etymological kin to a shave, just a far less consensual one.
