Abstract: A compressor assembly may include a compressor housing and a compressor impeller disposed within the compressor housing. The compressor housing may have an internal aerodynamic surface that defines a circumferentially extending volute, and the compressor impeller may have an external aerodynamic surface that faces toward at least a portion of the internal aerodynamic surface of the compressor housing. A nonstick coating may be formed on the internal aerodynamic surface of the compressor housing or on the external aerodynamic surface of the compressor impeller. The nonstick coating may prevent foreign material introduced into the compressor assembly from collecting on the internal aerodynamic surface of the compressor housing or on the external aerodynamic surface of the compressor impeller.

Abstract: A method for manufacturing an insert for an aluminum piston comprises applying pressure to a composition that comprises aluminum. The composition is deformed to form the insert for aluminum piston. The insert comprises an aluminum alloy and the insert functions as a ring carrier. Disclosed herein too is an article that comprises an insert for a piston. The article is manufactured from a composition that comprises aluminum. The insert is manufactured by a process that comprises applying pressure to the composition to form the insert.
