THE ADHESION OF ICE TO LUBRICATED SURFACES

摘要

The adhesion of ice to lubricated steel has been shown to vary over a wide range depending upon the polar organic additive present in the lubricating oil. The adhesion is least for systems showing contact angles of 170° or greater measured through water drops on steel submerged in the oil solutions. The extremely low adhesions observed in such systems arise because water does not readily displace the final thin film of bunk oil from the metal surface to establish true water/solid contact.
