摘要： Metal implants (10) are treated by anodising the surface (11, 12) in contact with an electrolyte, and then briefly subjecting the anodised surface to a reversed voltage. During a first anodising stage the surfaces are passivated, while during a subsequent anodising stage pits are formed in the passivating surface layer. Rough portions (15) of the surface, in particular portions produced by plasma spraying of metal powder, are sealed with a watertight cover (20) during at least part of the anodising process. After rinsing, biocidal metal ions are subsequently absorbed into the surface of the implant. This provides the implant with biocidal properties. The use of the cover (20) enables a more uniform geometric distribution of biocidal metal ions to be achieved.

摘要： In a process for anodising a metal object (12), the metal object (12) is contacted with an anodising electrolyte (32), and is first pre-anodised so as to grow a thin oxide film on the surface. The microscopic surface area is then deduced from electrical measurements either during pre-anodising or on the pre-anodised surface. The metal object (12) can then be anodised. This is applicable when treating an implant to provide a surface that has the ability to incorporate biocidal material such as silver ions. The pre-anodising uses a low voltage, for example no more than 2. V, and may take less than 120 seconds.
摘要翻译：在阳极氧化金属物体（12）的过程中，金属物体（12）与阳极氧化电解质（32）接触，并且首先被预阳极氧化以在表面上生长薄氧化膜。然后在预阳极氧化期间或在预阳极化处理的表面上从电测量推导出微观表面积。然后可以对金属物体（12）进行阳极氧化。当处理植入物以提供具有引入杀生物材料例如银离子的能力的表面时，这是适用的。预阳极氧化使用低电压，例如不超过2.V，并且可能需要少于120秒。

摘要： A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer is grown by anodising at a voltage between 50 and 150 V, and the biocidal material incorporated in it by ion exchange. This produces a significantly harder surface than anodising at low voltage, and generates pits containing ion-absorbing material.

摘要： An implant with a metal structure for use in a surgical procedure, in which at a region of the implant to be in contact with bone the metal structure is provided with a roughened surface. The roughened region is then provided with a ceramic coating comprising hydroxyapatite by a thermal spraying process. Biocidal ions of silver are absorbed into the ceramic coating, and gradually leach out into body fluids after implantation. The hydroxyapatite enhances bone regrowth into the implant, while the silver ions suppress infection.

摘要： A sensor for detecting chemical properties of a liquid, for example in an oil well, includes a glass pH electrode (22a) and a reference electrode (22c). The glass electrode (22a) consists of a narrow sensor electrode (30) on the surface of an electrically insulating substrate (20), a layer of glass (36) covering the sensor electrode (30), and two cleaning electrodes (32, 33) one extending along each side of the sensor electrode along its entire sensing length. The cleaning electrodes (32, 33) are not covered by the layer of glass, and are no more than 3 mm apart from each other. Application of a voltage between them generates gas bubbles by electrolysis that dislodge any fouling from the glass electrode (22a). The sensor electrode (30) may be of zigzag form, with the cleaning electrodes (32, 33) interdigitated between the successive parts of the zigzag. A hydrophilic membrane (24) of sulphonated microporous PVdF provides further protection against fouling of the electrodes (22) by oil. This provides a compact, solid state sensor, which can be cleaned in situ.

摘要： Precious metals can be selectively removed from a solution containing an excess of base metals by electrolysis in a divided cell. This necessitates controlling the pH of the solution, and controlling the voltage applied to the electrodes, such that precious metals are deposited preferentially on the electrode in contact with the solution. For example the precious metals may be deposited selectively onto an anode, presumably with formation of a hydrous oxide, if the pH is held at say less than pH 1.0 and the cell voltage held less than 1.3 V.

摘要： Metal objects are treated by anodising the metal object in contact with an aqueous electrolyte, and then subjecting the anodised metal object to a reversed voltage. The anodising is performed in two stages, firstly to passivate with the formation of an oxide layer, and secondly to form regions in the oxide layer having a higher oxygen to metal atom ratio, for example pits or caps, in this oxide layer. The second stage of anodising is performed by applying a multiplicity of voltage cycles, each voltage cycle involving ramping the voltage between a lower threshold voltage and an upper threshold voltage, and then returning to the lower threshold voltage. The reversed voltage step forms a hydrous metal oxide in the regions of higher oxygen to metal atom ratio, and the oxide layer and hydrous metal oxide together constitute a surface layer which is integral with the metal object, and has ion exchange capacity. After the reversed voltage step the metal object is then contacted with a bio-effective material such as a biocidal metal, which is absorbed into the surface of the metal object. The processing time may be reduced by applying the multiple voltage cycles. The invention also provides a treated metal object which can be prepared by treating a metal object having a micro-rough surface according to the method described above.

摘要： Metal implants (10) are treated by anodising the surface (11, 12) in contact with an electrolyte, and then briefly subjecting the anodised surface to a reversed voltage. During a first anodising stage the surfaces are passivated, while during a subsequent anodising stage pits are formed in the passivating surface layer. Rough portions (15) of the surface, in particular portions produced by plasma spraying of metal powder, are sealed with a watertight cover (20) during at least part of the anodising process. After rinsing, biocidal metal ions are subsequently absorbed into the surface of the implant. This provides the implant with biocidal properties. The use of the cover (20) enables a more uniform geometric distribution of biocidal metal ions to be achieved.
