An abradable coating is described for interaction with a abrasive gas turbine engine component to provide sealing. The abradable coating comprises yttria stabilized zirconia with intentional porosity which is applied by plasma spraying to a MCrAlY bond coat which in turn rest on a superalloy substrate. The coating system is applied by plasma spraying. The coating system is adapted to interact with an abrasive coated abrasive treated gas turbine engine component.
