Surgical Implant Coatings
Part 2. titanium and titanium - 6 aluminum - 4 vanadium alloy powder
1 Scope
This part of YY/T 0988 specifies the use of pure titanium powder and titanium-6 aluminum-4 vanadium alloy powder for the formation of coatings on titanium alloy implants
Claim.
The powder specified in this section may be formed by a sintering process or a thermal spraying process.
This section specifies the requirements of the powder and does not apply to the performance of the powder made of the coating.
Note. Fine titanium powder may cause spontaneous combustion, handling should be consistent with the relevant guidelines.
