A kit for reaming a portion of a long bone cavity for use in implanting a joint prosthesis, the reamers for cooperation with portions of an orthopaedic implant component. The cooling microcircuit comprises a channel through which a cooling fluid flows, at least one exit hole for distributing cooling fluid over a surface of the turbine blade, and internal features within the channel for accelerating the flow of cooling fluid prior to the cooling fluid flowing through the at least one exit hole. The present invention enhances the heat and humidity resistances and the stability of the PVA base film, and improves its mechanical performance and sticking-resistance.
