1. A method of manufacturing a cobalt-base alloy implant component comprising the steps:

  • providing a bar stock of biocompatible cobalt-base alloy; and

    precision machining the bar stock under conditions sufficient to remove metal from said bar stock to form an implant component of predetermined shape without deforming the structure of said alloy sufficiently that the mean average increase in surface defects of a size above 5 micrometers is greater than 10 when said implant component is subjected to accelerated chemical aging. by immersing the component in human synovial fluid inside a sealed pressure vessel and heating the pressure vessel to a temperature of 159°

    C. plus or minus 1°

    C. for 8.6 days.
