Coating, Thermal Spray High Velocity Oxygen/Fuel Process
|Publication Date:||1 January 2012|
This specification covers the requirements for thermal spray coatings applied using the high velocity oxygen fuel (HVOF) combustion process. This specification is not intended to be used for duplex coatings, i.e., the application of the coating over a previously applied coating.
This process has been used typically to provide coatings of lower porosity and higher adhesive, and/or cohesive, strength than generally attainable with typical plasma spray processes for applications requiring wear, heat, and corrosion resistance and for dimensional restoration, but usage is not limited to such applications.
Safety - Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
Type 1 - Coatings with no residual stress requirements
Type 2 - Coatings where the residual stress state is specified
If no Type is specified Type 1 shall be provided.
