Abstract

An abradable coating is formed on portions of the flank wall of the wraps of a scroll compressor. The radially outer portions of the flank wall are left uncoated, and can bear a force between the scroll wraps. In this manner, the load is not transferred through a coated portion, but rather through the uncoated portion. As the scroll wraps move relative to each other at run-in, the abradable coating wears away leaving a tight fit between the flank walls at the radially inner locations.
