本规范涵盖了使用高速氧燃料（HVOF）燃烧工艺涂敷的热喷涂涂层的要求。本规范不适用于双重涂层，即在先前涂覆的涂层上涂覆涂层。该工艺通常用于提供孔隙率较低、附着力和/或内聚力较高的涂层，其强度比要求耐磨性、耐热性和耐腐蚀性的应用以及尺寸恢复的典型等离子喷涂工艺所能获得的涂层强度高，但其用途不限于此类应用。

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 duples 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.
