APPLYING BOND COAT TO ENGINE COMPONENTS USING COLD SPRAY

摘要

PROBLEM TO BE SOLVED: To provide a process for applying a coating to a component used in an engine. SOLUTION: The process comprises a step of providing a component 10 with at least one surface 24 to be coated, and a step of depositing at least one layer of powder coating material onto the at least one surface 24 using a non-oxidizing carrier gas so that the powder coating material plastically deforms without melting and bonds to the at least one surface 24 upon impact with the at least one surface 24. The process of the present invention has particular utility in applying bond coats to airfoil portions of turbine blades or vanes and to applying bond coats to combustion chamber liners.
