Hereinafter, embodiments of the present invention will be described in detail.

1. 1. Abrasion Resistant Film FIG. 1 is a schematic cross-sectional view showing an example of an abrasion resistant member provided with the abrasion resistant film of the present invention. The wear-resistant film 10 of the present invention includes a plating layer 11, a plurality of particles 12, and a coat layer 13, and one end of the plurality of particles 12 is held by the plating layer 11, and the coat layer is held. 13 is formed so as to cover the surfaces of the plurality of particles 12 and the plating layer 11.

In the embodiment of FIG. 1, the wear-resistant film 10 is coated on the surface of the base material 20, and the surface of the wear-resistant film 10 on the plating layer 11 side is fixed to the surface of the base material 20. .. That is, the base material 20, the plating layer 11, and the coat layer 13 are laminated in this order, and a plurality of particles 12 held by the plating layer 11 are arranged on the surface of the base material 20. As a result, the wear resistant member 30 is formed.

The plating layer 11 is a layer formed by the plating treatment. The plating layer 11 is a layer formed by, for example, electrolytic plating, electroless plating, or the like.

The plating layer 11 is a layer capable of holding a plurality of particles 12 in the abrasion resistant film 10.

Examples of the plating layer 11 include plating layers of various metals. The metal forming the plating layer 11 is not particularly limited. Specific examples of the metal include nickel, zinc, cobalt, tin, copper, silver and the like.

The metal forming the plating layer 11 may be only one type or two or more types. Further, the metal forming the plating layer 11 may be an alloy. Alternatively, the metal forming the plating layer 11 may be an oxide, a nitride, a sulfide, or the like. Further, the plating layer 11 may have other elements (for example, non-metal elements such as phosphorus and boron) as constituent elements in addition to or in place of the metal.

As the plating layer 11, for example, based on metal plating such as Ni, fluororesin (PTFE), mica, alumina (Al ₂ O ₃ ), boron nitride (BN), silicon carbide (SiC), molybdenum disulfide ( It may be a composite plating in which _{MoS 2} ), tungsten disulfide (WS ₂ ), silicon dioxide (SiO _{2) and the like are combined.}

Examples of the plating layer 11 include an electroless nickel plating layer (electroless nickel plating layer) formed by an electroless plating treatment and an electroless Ni-P composite plating layer. When the plating layer 11 is an electroless Ni-P composite plating layer, the hardness and corrosion resistance of the plating layer 11 can be improved by the effect of co-deposited P.

The method for forming the plating layer 11 is not particularly limited, and for example, the plating layer 11 can be formed by various known methods. As a specific example of the forming method, for example, electroplating, electroless plating, hot dip plating, vapor phase plating and the like can be used. The plating treatment method may be either a continuous method or a batch method.

The plating layer 11 may also have a multi-layer structure. For example, when the plating layer 11 has a two-layer structure formed by a first layer and a second layer, the first layer is formed by electroplating and the second layer is formed by electroless plating. It can be a layer. In this case, for example, the second layer can be arranged on the coat layer 13 side, and vice versa.

The thickness of the plating layer 11 is not particularly limited, and the thickness can be such that the particles 12 can be fixed. For example, the thickness of the plating layer 11 can be 0.1 μm to 1 mm, more preferably 1 to 100 μm, and particularly preferably 1 to 10 μm.

The plating layer 11 is a layer in the wear-resistant film 10 that is in direct or indirect contact with the base material 20. When the plating layer 11 indirectly contacts the base material 20, for example, an electrodeposition layer formed by a method such as electroplating described later is arranged between the plating layer 11 and the base material 20.

The particles 12 can play a role like a strut in the thickness direction of the wear-resistant film 10, and can have a function of maintaining the wear resistance of the wear-resistant film 10 for a long period of time.

The type of the particles 12 is not particularly limited. Known materials can be used as the particles 12, and examples thereof include diamond, cBN, alumina, silica, silicon carbide, and other inorganic materials that can be used as abrasive grains such as abrasives.

The particles 12 may have pores. In this case, for example, when the wear-resistant film 10 is impregnated with oil, the oil permeates into the pores of the particles 12, so that the oil retention property can be exhibited.

A plurality of particles 12 are contained in the wear-resistant film 10.

One end of each of the plurality of particles 12 is held by the plating layer 11. As a result, the plurality of particles 12 can be regularly or irregularly arranged on the plating layer 11. When the particles 12 have sharp portions such as diamond, for example, as shown in FIG. 1, the sharp portions are regularly oriented in the direction opposite to the plating layer 11, that is, toward the coat layer 13. However, it is not always arranged in such a regular manner, and some particles 12 may be arranged so as to face different directions.

The amount of the particles 12 contained in the abrasion resistant film 10 is not particularly limited. For example, when the particles 12 are contained in an amount of 10 to 90 vol% with respect to the abrasion resistant film 10, the effect of the present invention is remarkable. Can be demonstrated in.

The particles 12 are provided so that a part thereof protrudes from the surface of the plating layer 11. For example, more than half of the total thickness of the particles 12 may be provided so as to protrude from the surface of the plating layer 11.

The size of the particles 12 is not particularly limited. For example, the size of the particles 12 can be appropriately selected according to the film thickness of the wear resistant film 10. For example, when the particles 12 are regarded as spherical and have a maximum primary particle diameter of 30 μm, the thickness of the plating thickness 11 can be set to such that the particles 12 can be fixed.

The coat layer 13 is a layer formed so as to cover the surfaces of the plurality of particles 12 and the plating layer 11 in the abrasion resistant film 10. The coat layer 13 is located on the outermost surface of the wear-resistant film 10, and is a layer capable of imparting wear resistance and slidability to the base material 20 and the like.

The coat layer 13 can be formed of a known material having wear resistance.

Specific examples of the coat layer 13 include films formed of various materials such as resin and metal.

Examples of the resin include a fluorine-based resin. Examples of the fluororesin include polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene-hexafluoropropylene copolymer, polychlorotrifluoroethylene and tetrafluoroethylene-ethylene copolymer. Coalescence etc. can be mentioned. The fluororesin may have, for example, a particulate shape. The fluororesin may contain one kind or two or more kinds.

Examples of the metal include nickel, chromium, copper, tin, silver, titanium, iron, molybdenum and the like. The metal can include one kind or two or more kinds. The metal forming the coat layer 13 may be an alloy. Alternatively, the metal forming the coat layer 13 may be an oxide, a nitride, a sulfide, or the like. Further, the coat layer 13 may have other elements (for example, non-metal elements such as phosphorus and boron) as constituent elements in addition to or in place of the metal.

The coat layer 13 can also contain, for example, both resin and metal. When both the resin and the metal are contained, the mixing ratio of both is not particularly limited, and an appropriate mixing ratio can be used in order to exhibit the desired wear resistance.

The method for forming the coat layer 13 is not particularly limited. For example, a known method of forming a film can be adopted. Specifically, the coat layer 13 can be formed by a plating treatment method such as electroplating, electroless plating, hot dip galvanizing, vapor phase plating, or other various methods such as coating and sputtering. The plating treatment method may be either a continuous method or a batch method.

In particular, the coat layer 13 preferably contains at least one selected from the group consisting of polytetrafluoroethylene, molybdenum disulfide, silver and chromium. In this case, the coat layer 13 is particularly excellent in wear resistance, and the effect of the present invention can be remarkably exhibited. In particular, the coat layer 13 is formed by electroless plating at least one material selected from the group consisting of polytetrafluoroethylene and molybdenum disulfide, silver and chromium (for example, hard chromium). preferable. The coat layer 13 may be formed of only one material selected from the group consisting of polytetrafluoroethylene and molybdenum disulfide. Alternatively, the coat layer 13 may contain, in addition to at least one material selected from the group consisting of polytetrafluoroethylene and molybdenum disulfide, other materials to the extent that the effects of the present invention are not impaired.

As described above, the coat layer 13 is formed so as to cover the surfaces of the plurality of particles 12 and the plating layer 11. The coat layer 13 can be formed so as to cover all of the plurality of particles 12. From the viewpoint of enhancing the initial familiarity, it is preferable that the coat layer 13 covers all the plurality of particles 12.

The thickness of the coat layer 13 is not particularly limited. For example, the thickness of the coat layer 13 can be at least 1 μm or more. The upper limit of the thickness of the coat layer 13 can be appropriately set according to the thickness of the plating layer 11, and for example, the thickness can be adjusted so that the exposed portion of the particles 12 can be completely covered with the coat layer 13.

The wear-resistant film 10 of the present invention can be suitably used for various members as a film for imparting wear resistance, and the wear-resistant member 30 described later can be formed. When various members are coated with the wear-resistant film 10 of the present invention, the wear-resistant film 10 is coated so that the coat layer 13 is located on the surface side.

By providing the coat layer 13 having excellent wear resistance, the wear-resistant film 10 of the present invention can impart high wear resistance and slidability, and in particular, the particles 12 are contained in the wear-resistant film 10. Since a plurality of them are contained, the effect of wear resistance is not easily lost even if wear is repeated.

More specifically, even though the wear-resistant film 10 has a coat layer 13 having excellent wear resistance, the coat layer 13 may be scraped or damaged if the wear is repeated for a long period of time. Yes, this may allow the coat layer 13 to gradually lose its wear resistance and slidability. When the coat layer 13 is worn away by wear in this way, the tips of the particles 12 existing in the wear-resistant film 10 are eventually exposed on the surface of the wear-resistant film 10. When the coat layer 13 is scraped and the particles 12 are exposed to a certain thickness (for example, when the coat layer 13 is scraped to the broken line portion in FIG. 1), the exposed particles 12 prevent the coat layer 13 from being scraped and damaged. Can be done. As a result, even if the surface of the wear-resistant film 10 is continuously worn, it is less likely to be worn or damaged due to the wear of the coat layer 13.

In the conventional wear-resistant film, if the film continues to be worn, the film also continues to be scraped, and the coat layer may gradually disappear to lose the wear resistance. However, the wear-resistant film 10 of the present invention is described above. By providing the structure, the effect of wear resistance can be maintained for a longer period of time than before. Further, by flattening the tip portion of the particles in advance by polishing and increasing the exposed area of the particles, it is possible to suppress an increase in the initial wear amount.

2. Abrasion-resistant member As shown in FIG. 1, the wear-resistant member 30 of the present invention includes an abrasion-resistant film 10 and a base material 20, and the base material 20 is coated with the wear-resistant film 10. In the wear-resistant film 10, the surface of the plating layer side 11 is fixed to the base material 20.

The wear-resistant film 10 has the same configuration as that described in the section “1. Wear-resistant member” of the present specification.

Various solid materials can be applied to the base material 20, and the type thereof is not particularly limited. For example, various materials such as metal (for example, iron), alloys, resins, ceramics, paper, wood, and cloth can be used as the base material 20.

The shape of the base material 20 is not particularly limited. For example, the shape of the base material 20 may be a substrate shape, a film shape, a rod shape, a block shape, a spherical shape, an elliptical spherical shape, a distorted shape, or the like. Further, the base material 20 may be various mechanical parts, tools, dies, bearings, sleeves and the like. The portion of the base material 20 covered with the wear-resistant film 10 may have either a flat shape or a non-flat shape (concave and convex shape, rough surface shape, wavy shape, etc.).

The surface of the wear-resistant film 10 on the plating layer side 11 can be directly fixed to the base material 20. Alternatively, another layer may be interposed between the surface of the wear-resistant film 10 on the plating layer side 11 and the base material 20, and the wear-resistant film 10 may be fixed to the base material 20. In this case, as the other layer, an electrodeposition layer formed by a method such as electroplating described later is arranged.

By providing the wear-resistant film 10 in the wear-resistant member 30 of the present invention, excellent wear resistance can be maintained for a long period of time even if wear is repeated.

As another aspect of the wear resistant member 30, the base material 20, the plating layer 11, the plurality of particles 12, and the coat layer 13 are provided, and one end of the plurality of particles 12 is held by the plating layer 11. The plating layer 11 is fixed to the base material 20, and the coating layer 13 covers the plating layer 11 and is formed so that a part of the particles 12 protrudes from the surface of the coating layer 13. Can be done. The wear-resistant member 30 of this form, for example, the coat layer 13 is scraped by wear as described above, and the particles 12 are exposed on the surface. In this aspect, the coat layer 13 is less likely to be scraped due to wear due to the effect of the particles 12 exposed on the surface, so that the wear resistance is less likely to be lowered. All of the plurality of particles 12 may protrude from the surface of the coat layer 13, or some of the plurality of particles 12 may protrude from the surface of the coat layer 13.

3. 3. Method of Forming Abrasion Resistant Film The method of forming the abrasion resistant film 10 is not particularly limited, and the abrasion resistant film 10 can be produced by various methods as long as the above-described configuration is provided. Hereinafter, as an example, a method of forming the abrasion resistant film 10 on the base material 20 will be described.

The wear-resistant film 10 includes a step of performing a first plating treatment on a base material 20 on which a plurality of particles 12 are electrodeposited, and a second step for coating the surface of the plurality of particles with a coat layer 13. It can be formed by a method including a step of performing a plating process.

The particles 12 used in the method of the present invention have the same configuration as that described in the section “1. Abrasion resistant film”. Further, the base material 20 used in the method of the present invention has the same configuration as that described in the section “2. Abrasion resistant member”.

Prior to the first plating treatment, the base material 20 obtained by electrodepositing a plurality of particles 12 can be prepared. The method of electrodepositing the plurality of particles 12 on the base material 20 is not particularly limited. For example, the particles 12 can be electrodeposited on the base material 20 by a known method such as electroplating. In this case, the plurality of particles 12 can be held by an electrodeposition layer (not shown) formed by electrodeposition.

The method of the first plating treatment is not particularly limited. As the plating method, conventionally known electroplating, electroless plating, hot dip galvanizing, vapor phase plating and the like can be used. The plating treatment method may be either a continuous method or a batch method.

In the first plating process, plating layers of various metals can be formed. Specific examples of the metal include nickel, zinc, cobalt, tin, copper, silver and the like. As the first plating treatment, for example, electroplating and / or electroless nickel plating can be adopted.

By the first plating treatment, the plating layer 11 is formed, and the plurality of particles 12 can be strongly held by the base material 20. The plating layer 11 has a two-layer structure formed by the electrodeposition layer and a layer formed by the first plating treatment. The plating layer 11 is not limited to such a two-layer structure, and may be, for example, only a layer formed by the first plating treatment. In this case, the plurality of particles 12 are retained only by the first plating process.

The first plating treatment is performed so that a part of the particles 12 protrudes from the surface of the plating layer 11 formed by the first plating treatment. For example, the first plating treatment can be performed so that more than half of the total thickness of the particles 12 protrudes from the surface of the plating layer 11.

By the first plating treatment, the plurality of particles 12 electrodeposited on the base material 20 are held by the plating layer 11 formed by the first plating treatment, and the particles 12 are more firmly fixed to the base material 20. obtain.

After the first plating process, the second plating process is performed. The coat layer 13 is formed by this second plating treatment. The coat layer 13 covers the surface of the particles 12.

The method of the second plating treatment is also not particularly limited. As the plating method, conventionally known electroplating, electroless plating, hot dip galvanizing, vapor phase plating and the like can be used. The plating treatment method may be either a continuous method or a batch method.

The second plating treatment is preferably an electroless plating treatment in that the coat layer 13 can be easily formed.

The second plating treatment can be performed using, for example, a material such as resin or metal.

For the second plating treatment, it is preferable to use at least one selected from the group consisting of polytetrafluoroethylene and molybdenum disulfide. In this case, since the coat layer 13 formed by the second plating treatment is formed of a material containing at least one selected from the group consisting of polytetrafluoroethylene and molybdenum disulfide, the abrasion resistance film 10 is resistant to wear. Especially excellent in abrasion resistance. The coat layer 13 containing at least one selected from the group consisting of polytetrafluoroethylene and molybdenum disulfide is preferably formed by electroless plating.

By the second plating treatment, the plurality of particles 12 and the plating layer 11 formed by the first plating treatment are coated with the coat layer 13. In this second plating treatment, it is preferable that all of the plurality of particles 12 projecting from the plating layer 11 are covered with the coat layer 13. In this case, wear resistance can be sustained for a longer period of time.

As described above, the wear-resistant film 10 is formed on the base material 20, and the wear-resistant member 30 is formed.

The wear-resistant film 10 and the wear-resistant member 30 obtained by the method of the present invention can maintain excellent wear resistance for a long period of time even if wear is repeated.

Therefore, the method of the present invention and the wear-resistant film 10 and the wear-resistant member 30 can be suitably used for various members. Examples of applicable members include various mechanical parts, tools, molds, and the like, as well as various sliding parts such as those used for household goods, industrial machines, transport aircraft, leisure goods, and the like.
