摘要：A method of making a prosthetic bearing element which comprises a backingmade from a \"rigid\" polymeric bearing material which has a minimum hardness value of 65N/mm<2> and which supports a bearing liner having a bearing surface and made from a\"soft\" elastomeric polyurethane material having a hardness value of 3.0 to 9.0 N/mm<2>(using machine testing method BS 2782; Pt3 method 365D) characterised in that theopacity of said bearing liner is arranged to allow the passage of a laser beam through itand the opacity of said backing is arranged to prevent the passage of said laser beamwhich has passed through said bearing liner, bonding the backing to the bearing liner andthen treating the bearing liner and backing with said laser beam to cause improved fusionby laser welding.
