するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method of forming a plating layer of a composite material on the surface of an object to be plated, and in particular, relates to a method of eutectoiding a dispersion material into a matrix metal layer. The present invention relates to such a composite plating method.

れることが多い。(Prior Art) Screws and cylinders of resin processing machines, cylinders and piston rings of heat engines, poles constituting valves of fluid transport equipment, etc. are required to have high wear resistance and corrosion resistance. Therefore, composite plating in which a hard dispersion material is eutectoided in the matrix metal of the plating layer is often applied to the surface of such devices.

クス金属２の層中に分散材３が共析したものとなる。Such composite plating is performed by adding dispersed materials such as powder or fibers, such as carbides, ferrides, oxides, nitrides, or mixtures thereof, into a plating bath containing metal ions as a base (matrix). It is obtained by dispersing and suspending the electrolyte, using the object to be plated as a cathode, and using a matrix metal plate such as a nickel plate as an anode, and passing an appropriate current between these electrodes. As shown in Fig. 1, the composite plating layer thus obtained is one in which the dispersion material 3 is eutectoid in the layer of the matrix metal 2 deposited on the surface of the substrate 1 of the object to be plated. Become.

をそのまま用いるようにしていた。When performing such composite plating, conventionally, as the dispersing material, one formed in the form of powder or granules or HIi fibers was used as is.

ちぬれ性は、全くあるいはほとんどと言ってよいほどな
い、そのために。(Problems to be Solved by the Invention) However, in such composite plating, there is generally no or almost no compatibility, or wettability, between the matrix metal 2 and the dispersion material 3. for that.
複合めっき面の摩擦によってマトリックス金属２が摩滅

材３が砥粒として作用するので、その複合めっきの摩耗
が一層促進されるとともに、相手材の表面をも著しく摩
耗させるという問題が生ずる。When the matrix metal 2 is worn away by the friction of the composite plating surface and the dispersion material 3 is exposed and protrudes from the surface, the dispersion material 3 easily falls off due to the frictional force. Not only will the abrasion resistance of the composite plating due to the dispersion material 3 no longer be obtained, but the dispersion material 3 that has fallen off will act as abrasive grains, further accelerating the wear of the composite plating, and will also significantly damage the surface of the mating material. The problem arises of wear.

を施すようにする。Surface treatment methods for roughening the surface of the dispersion material include chemical treatment methods, mechanical treatment methods, electrical treatment methods, thermal treatment methods, and composite treatment methods that combine appropriate methods among these. If a chemical treatment method or a mechanical treatment method is used, a large amount of dispersion material can be treated quickly and inexpensively. Note that dispersion materials such as silicon carbide, aluminum oxide, titanium oxide, and tungsten carbide have high hardness and rigidity, so it is difficult to make the surface sufficiently rough even with mechanical treatment methods. In the case of a dispersion material, surface treatment should be performed using a chemical treatment method.

散材の脱落が防止されるようになる。(Function) By roughening the surface of the dispersion material in this way, the specific surface area of the dispersion material increases. Therefore, if composite plating is performed using such a dispersion material, the dispersion material will come into contact with the matrix metal over a large area, and moreover, the matrix metal will engage with the irregularities on the surface. As a result, the dispersion material and the matrix metal are bonded with sufficient bonding force, and the dispersion material is prevented from falling off from the matrix metal.
