8、with appreciation their dedication and contribution of time and effort on behalf of ASTM.Printed in Fredericksburg,VA October 1999 Foreword This publication,Cobalt-Base AUoysfor Biomedical Applications,contains 17 papers presented at the symposium of the same name,held on November 3 and 4,1998,in No
9、rfolk,Virginia.The symposium was sponsored by ASTM Committee F-4 on Medical and Surgical Materials and Devices.John A.Disegi from Synthes(USA),West Chester,Pennsylvania,Richard L.Kennedy from Allvac,Monroe,North Carolina,and Robert Pilliar of the University of Toronto,Toronto,Ontario,Canada presided
10、 as symposium chairmen and are editors of the resulting publication.The scope of the symposium was intended to cover topics that have emerged in recent years such as alloy design,processing variables,corrosion/fretting resistance,abrasion and wear characterization,implant surface modification,biolog
11、ical response,and clinical performance.Although cobalt-base alloys are used extensively for a variety of dental,orthopaedic,neurological,and cardiovascular applications,the major portion of the publication is focused on orthopaedic applications.The editors would like to express their appreciation fo
