    摘要： Method of providing a desired material on at least a portion of a surface of a substrate of a component, such as a medical implant component. The method may comprise the steps of arranging the component in a holding fixture which is capable of holding the component at atmospheric or substantially atmospheric pressure, and spraying particles of the desired material at a predetermined high velocity toward the at least one portion of the surface of the substrate so as to enable a layer of the material to be accumulated thereon. The spraying may be performed at atmospheric or substantially atmospheric pressure. The desired material may be a reactive type material, such as titanium or an alloy thereof. The method may enable a high density coating or layer of the material to be provided without the use of a post spray thermal consolidation process.

    摘要： A prosthetic medical device exhibiting improved wear resistance is fabricated by sealing at least one polyolefinic material in an airtight container and providing an inert atmosphere within the airtight container. The polyolefinic material is exposed to an irradiation source to yield a cross-linked irradiated polyolefinic material. At least one non-irradiated polyolefinic material is blended with the irradiated polyolefinic material, and the prosthetic medical device is formed from the blended material. Selectively cross-linked polymeric compositions may be created by blending a specific amount of cross-linked resins with a specific amount of uncross-linked resins then cured into a polymeric matrix whereby the desired degree or percentage of overall cross-linking is obtained. The polymeric material may then be formed directly into a finished article by injection molding the polymeric material.

    摘要： A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.

    摘要翻译： 一种生产改进的聚乙烯，特别是超高分子量聚乙烯的方法，该聚乙烯利用顺序的照射和退火工艺来形成高度交联的聚乙烯材料。 在每次照射之后使用顺序照射，然后进行顺序退火，允许在一系列剂量中的每个剂量的照射相对较低，同时实现足够高的交联材料的总剂量。 该方法可以应用于预成型材料，例如由聚乙烯树脂制成的棒或棒或片，或者可以施加到成品聚乙烯部分上。 如果应用于成品聚乙烯部件，照射和退火必须用不超过1体积氧浓度的氧气接触的聚乙烯材料完成。 当应用于诸如棒的预成型件时，制造成品部件的棒的主体聚合物部分的退火必须在植入物从其加工并暴露于氧之前在棒上进行。
