Alternatively, it can be used to improve the wear resistance of composite plating films formed on roll surfaces that are subject to high surface pressure. [Prior Art] As means for improving the wear resistance of metal materials, there are heat treatment methods, carburizing methods, and methods of coating superhard materials (e.g., hard ceramics, cermets) by thermal spraying, chemical vapor deposition, etc. Composite plating (for example, Japanese Patent Publication No. 18080/1980) is known as another method for improving the wear resistance of metal materials. In composite plating, a composite plating film is formed on the surface of a base metal by electroplating using a plating bath in which eutectoid particles are suspended.

Also, composite plating film When the hardness of the metal matrix coating is low, the metal matrix plating coating cannot support the fine powder particles broken down during composite plating due to the high surface pressure, and the powder particles are separated from the coating due to frictional force and the surface Scratches off the surface and causes severe wear.

０ＰＩＩ１以下でなければならない。In order to improve the wear resistance of a composite plating roll, the metal matrix plating must have a Vickers hardness of 700 or more, and the Vickers hardness of the fine powder particles to be dispersed must be higher than the Vickers hardness of the metal matrix plating film. The hardness of the metal matrix film is 700 on the Vickers scale.
If the Vickers hardness of the powder particles in the plating film is lower than the hardness of the plating film, the wear resistance cannot be further improved compared to wear-resistant materials such as conventional rolling rolls. . Furthermore, in order to obtain a composite plating film with excellent wear resistance, the amount of fine powder particles dispersed in the composite plating film must be 10voR% to 60%.
volN, the average particle size of the fine powder particles to be dispersed is 1 μm ~
10 Pm, and the thickness of the composite plating film must be three times or more the average particle diameter of the fine powder particles. If the content of fine powder particles in the composite plating film is less than 10 vofl96, it is impossible to obtain a material that has better wear resistance than conventional wear-resistant materials, as shown in FIG. In addition, the content of fine powder particles in the composite plating film is 60 vol9g.
When the thickness becomes too large, the metal matrix plating film cannot support the fine powder particles and the film itself lacks strength, resulting in severe wear. Even if the particle size of the powder particles is less than 1 μm, sufficient wear resistance cannot be obtained compared to conventional wear-resistant materials, as shown in FIG. Furthermore, unless the thickness of the composite plating film is at least three times the average particle size of the powder particles, the strength of the composite plating film itself will be reduced, the powder particles will chip off, and no improvement in wear resistance can be expected. In addition, with the current plating technology, it is difficult to form a plating film of 30 μm or more with a Vicker hardness of 700 or more. Therefore, the particle size of the powder particles dispersed in the plating film is 1.
Must be less than 0PII1.

The Nl-based composite plating film was applied to conventional cold rolling rolls. Then, a regular steel plate (thickness: 3 mm) of a certain length was cold rolled at a rolling reduction rate of 20% using a quadruple rolling mill equipped with this cold rolling roll. As a result, the wear depth of the cold rolling roll on which the composite plating film conforming to the claims of the present invention is formed is as follows:
As shown in Table 1, conventional cold rolling rolls (Fe-C-C
It can be seen that the wear depth is smaller than that of R-series forged steel rolls, indicating that it has excellent wear resistance. [Effects of the Invention] According to the present invention, the composite plated roll of the present invention can be improved by using a plated film having the same level of hardness as a conventional rolling roll and powder fine particles having higher hardness than the plated film as a dispersant. Wear resistance is further improved. As a result, it is possible to reduce product costs and improve productivity and work efficiency.
