HVOF-Coating and Honing of Cylinder Bores - Method and Apparatus for the Application of Thermal Spray Coatings onto Aluminium Engine Cylinder Bores and Final Honing Process

摘要

This paper presents background and detail information concerning the application of thermally sprayed metal alloy coatings onto the I.D. surfaces of aluminum block engine cylinder bores using a rotating extension HVOF spray gun. A fixturing method that allows the elimination of fixture cleaning and part masking is described. A new approach and technique that replaces grit blasting for surface preparation is also discussed [1].
