This specification covers the requirements for cobalt-28chromium-6molybdenum alloy powders for coating of orthopedic implants. This specification covers powder requirements only and does not address coating properties. Materials may be manufactured by rotating electrode process, inert gas atomization, or other methods that meet the powder requirements of this specification. The powder shall conform to chemical composition, sieve analysis, and cleanliness requirements of this specification.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the requirements for cobalt-28chromium-6molybdenum alloy powders for use in fabricating coatings on cobalt-28chromium-6molybdenum alloy orthopedic 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 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
