Standard Specification for Titanium and Titanium-6 Aluminum-4 Vanadium Alloy Powders for Coatings of Surgical Implants
This specification covers the chemical, particle size, and cleanliness requirements for unalloyed titanium and titanium-6aluminum-4vanadium alloy powders for use as coatings, formed by sintering or thermal spraying techniques, onto titanium alloy surgical implants. The powders may be manufactured by the plasma rotating electrode, inert gas atomization, or hydride-dehydride process, or other method capable of producing powder meeting the requirements of this specification. This specification addresses only the powder requirements, and not the properties of the coatings formed from them.
1.1 This specification covers the requirements for unalloyed titanium and Ti-6Al-4V alloy powders for use in fabricating coatings on titanium alloy implants.
1.2 Powders covered under this specification may be used to form coatings by sintering or thermal spraying techniques.
1.3 This specification covers powder requirements only. It does not address properties of the coatings formed from them.
1.4 Finely divided titanium powder may be considered pyrophoric and should be handled in accordance with the appropriate guidelines.
