Abstract

The present disclosure relates to a method of preventing residues of non-combusted ED95 from depositing on surfaces of a turbocharger of a vehicle by coating the relevant surfaces with a coating having a reduced affinity for ED95 residues. The coating is a thermal barrier coating (TBC) having both thermal barrier properties and modified surface properties. Thus, two advantages are achieved with a single coating: thermal losses are reduced and deposition of ED95 residues is prevented. Turbocharger components coated with a TBC, such as the turbine shaft, bearing housing, turbine wheel and blades, are also disclosed.
