摘要： Sprays of different material compositions A and B are directed to form a layer of coincident deposition of both material compositions A and B. The deposition is controlled such that a gradient of the relevant proportion of material composition A to material composition B is produced across the deposited layer. The provision of a controllable gradient of the relative proportion of material composition A to material composition B across the deposited layer enables the physical properties of the deposit to alter gradually across the depth of the deposit. The spray deposition method is useful when producing a machine tool, mould or die.

摘要： Metallic articles (21) having heat transfer channels are produced by solidification of molten metallic material (3, 4, 6) about preformed channel defining means (5) such that a solidified metallic deposit having heat transfer channels is formed. The channel defining means may be in the form of either solid elements (which are subsequently removed to leave the channels), or conduit elements (which may remain permanently embedded in the article). Moulds, dies, cores and other tools for use in moulding or casting of plastics and metals are particularly suitably formed by the process, the heat transfer channels being used for cooling of the respective articles during use. The molten metallic material is preferably deposited by spray forming utilising one or more sprays of molten metallic material.
摘要翻译：具有传热通道的金属制品（21）通过熔融金属材料（3,4,6）围绕预成形的通道限定装置（5）凝固而形成，从而形成具有传热通道的固化的金属沉积物。通道限定装置可以是固体元件（其随后被移除以离开通道）或导管元件（其可以保持永久地嵌入制品中）的形式。用于塑料和金属的模制或铸造的模具，模具，芯和其它工具特别适合地通过该方法形成，在使用期间用于冷却相应制品的传热通道。熔融金属材料优选通过使用熔融金属材料的一种或多种喷雾的喷射成形来沉积。

摘要： Protection of a metal surface is carried out by applying a coating of vitreous enamel to the surface so that the enamel forms a strong bond with the metal and then spraying a coating of an atomized protective metal on the enamel. Preferably a peening operation is carried out on the surface of the sprayed metal simultaneously with or immediately after the spraying of the metal. The method is particularly advantageous in protecting steel marine structures against corrosion and, where the protective metal is cupro-nickel, fouling by marine creatures. The vitreous enamel forms an electrically insulating layer preventing galvanic action between the steel and the cupro-nickel in the presence of sea water.
摘要翻译：金属表面的保护是通过在表面施加玻璃质釉质的涂层来实现的，使得搪瓷与金属形成牢固的结合，然后在搪瓷上喷涂雾化的保护金属的涂层。优选地，在喷射的金属的表面上同时或在喷射金属之后立即进行喷丸操作。该方法在保护钢海洋结构免受腐蚀和保护金属为铜镍的情况下特别有利于海洋生物的结垢。玻璃状搪瓷形成电绝缘层，防止在海水存在下钢和铜镍之间的电偶作用。

摘要： An apparatus for mixing a particulate substance, which may be in chopped or short fibre form, with a matrix metal comprises a container (11) for molten metal (10) having an aperture (12) through which a stream of the metal can fall, a feed motor (20) for feeding the particulate substance into the metal stream, and one or more downwardly inclined nozzles (23) through which jets of atomizing gas are directed on to the combined flow of metal and particulate substance. The feed motor comprising a horizontal ring (20a) which extends about and is coaxial with the molten metal stream, and which has a radial vibration imparted to it so as to form a node on the axis of the ring. The upper surface of the ring may be horizontal or may be inclined downwardly towards the axis and may have annular grooves of ratchet tooth section with the steeper part of the section facing towards the axis. The particulate substance is placed on the upper surface of the ring (20) and is caused to move into engagement with the molten metal stream by the radial vibration of the ring.
