DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wear-resistant lightweight member used for applications requiring wear resistance and lightweight, such as automobile parts, aircraft parts, precision machine parts, and the like, and a method of manufacturing the same. .

[0002]

2. Description of the Related Art Lightening of automobile parts and aircraft parts is strongly demanded from the viewpoint of improvement of fuel efficiency and the like, and lightweighting of precision machine parts is often desired. In addition, among these automobile parts and the like, in particular, parts that come into contact with a mating member are required to have high wear resistance.

Conventionally, as a material of a lightweight and wear-resistant part, a relatively light metal such as aluminum or aluminum alloy, magnesium or magnesium alloy, or titanium or titanium alloy, which is generally called light metal, is used. Usually, an alloy was used as a base material and its surface was subjected to a surface treatment for imparting wear resistance. As the surface treatment, a method of forming a hard anodic oxide film or plating such as hard chrome plating, a method of forming a ceramic film such as alumina or titanium nitride by PVD or sputtering, or a method of spraying a ceramic by spraying Various methods are known, such as a method of forming a film.

[0004] Recently, the demand for reducing the weight of automobile parts and the like has become more and more severe, and thus it has become difficult to sufficiently satisfy the requirements with the above-mentioned metals and alloys. On the other hand, recently, with respect to plastic materials, various engineering plastics or plastic-based composite materials in which lubricating fine particles are dispersed are sometimes used as wear-resistant members. Plastics have a density in the range of about 1 to 1.5 g / cm ³ , and are light metals such as aluminum, magnesium and titanium (the density is 2.7 g / cm ³ , 1.7 g / cm ³ and 4, respectively).
1 g / cm ³ ), and therefore, it is considered optimal to use plastic as a material only for the purpose of weight reduction.

[0005]

As described above, plastic materials are optimal for weight reduction, but are still insufficient in abrasion resistance. That is, among the light metals mentioned above, especially in the case of aluminum alloys, many studies have been conducted for a long time, and as a result, by forming various wear-resistant films such as hard alumite films on the surface, it is practically used at present. It is possible to obtain a sufficiently satisfactory abrasion resistance. However, in the case of plastic, even if it is an engineering plastic or a plastic composite material in which lubricating fine particles are dispersed,
Compared to the case where a wear-resistant film is formed on aluminum or aluminum alloy, the wear resistance is much lower, especially when large friction load is applied or when friction is applied at high speed, wear can be avoided. There is no fact. Of course, it is conceivable to form a hard film made of ceramic or the like on the surface of a plastic material by various methods. However, at present, it is difficult to ensure a sufficient adhesive force between the plastic and the hard film, and therefore, a large When a frictional load or high-speed friction is applied, the coating may be peeled off, so that it was practically difficult to use it as a wear-resistant part.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a member which is extremely excellent in light weight and also excellent in wear resistance.

[0022]

FIG. 1 schematically shows an example of a sectional structure of a wear-resistant lightweight member according to the present invention.

In FIG. 1, reference numeral 1 denotes a base material made of plastic, on which a plating layer 2 made of metal is formed as an intermediate layer. The thermal spray layer 3 made of ceramic is formed. The surface 1A of the substrate 1 is usually formed with a plating layer 2 after being subjected to a roughening treatment as described later. The surface 2A of the thermal sprayed layer 3 is also subjected to a surface roughening treatment as described later so as to have a roughened surface having a maximum roughness of 10 to 50 μm.
It is desirable to form

In the wear-resistant lightweight member of the present invention,
The base material 1 occupying the main part is made of plastic as described above. Generally, the density of plastic is extremely light, usually about 1 to 1.5 g / cm ^3. Therefore, by using plastic as the base material 1, it is possible to sufficiently secure the lightness of the wear-resistant lightweight member as a whole. it can.

On the other hand, the ceramic constituting the outermost thermal spray layer 3 generally has a high hardness, and therefore contributes to imparting sufficient wear resistance to the member. For example, in the case of the most common alumina (Al ₂ O ₃ ), its hardness is Hv8 in the case of thermal spraying.
00, hard anodized film (Hv400-5
Therefore, sufficient wear resistance can be provided by the ceramic sprayed layer. here,
When ceramic is sprayed directly on a plastic substrate,
The high temperature during thermal spraying causes the plastic surface to carbonize, which makes it difficult to ensure sufficient adhesion (peeling resistance) to the plastic substrate, and that the plastic substrate may be thermally deformed during thermal spraying. In addition, there is a problem that the plastic base material is thermally deformed by the heat due to friction when used as a wear-resistant member, and the thermal spraying tends to peel off the thermal sprayed layer. It has been considered that it is practically impossible to spray ceramics on the material and use it as a wear-resistant member. On the other hand, in the case of the wear-resistant lightweight member of the present invention, since the metal plating layer 2 is interposed between the plastic substrate 1 and the ceramic sprayed layer 3, such a problem is avoided and the ceramic sprayed layer 3 is prevented. Eliminates problems such as peeling
The wear resistance of the ceramic sprayed layer 3 can be sufficiently exhibited.

That is, when the ceramic sprayed layer is formed, the ceramic is sprayed on the metal plating layer. However, since the metal plating layer 2 has good thermal conductivity, heat during the spraying is reduced by the metal plating layer. The layer is transmitted and dispersed in the plane direction by the layer, so that carbonization of the surface of the plastic substrate due to high heat is prevented, and thermal deformation of the plastic substrate is also prevented. In addition, even when used as a wear-resistant part, heat due to friction is dispersed by the metal plating layer, so that the heat is prevented from being locally concentrated, and thermal deformation of the plastic base material is prevented. As described above, carbonization of the surface of the plastic substrate is prevented, so that the ceramic sprayed layer sufficiently adheres to the base (metal plating layer) and local thermal deformation is also prevented. Can be reliably prevented.

The surface of the metal plating layer is subjected to a surface roughening treatment such as blasting to adjust the surface roughness of the plating layer to a maximum roughness within a range of 10 to 50 μm. By forming the ceramic sprayed layer, the adhesion of the ceramic sprayed layer to the metal plating layer can be sufficiently increased by a so-called anchor effect.

Further, the operation of the present invention will be described in detail together with preferred embodiments.

The plastic used as the base material can be basically selected according to the intended use. Generally, it is a plastic having high strength, and a metal plating layer is formed thereon by chemical plating or the like. It is desirable to use a plastic for which a forming technique is established. Specifically, for example, acrylonitrile butadiene styrene copolymer resin, polyamide resin, polyacetal resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polycarbonate resin, polyphenylene oxide resin, epoxy resin, polystyrene resin, polysulfone resin, polyarylate resin, Acrylic resin, polyimide resin, hard vinyl chloride resin, high density polyethylene resin, polypropylene resin, phenol resin,
Polyurethane resin, fluororesin resin, unsaturated polyester resin, diallyl phthalate resin, silicone resin,
Polyphenylene sulfide resin, polyamide imide resin, polyallyl sulfone resin, polyether sulfone resin, polyphenylene ether resin, polyether ether ketone resin, oxybenzoyl polyester resin, and the like can be used.

On the plastic substrate 1 as described above, a plating layer 2 made of metal is formed as shown in FIG.
This plating layer 2 may be formed only by chemical plating, or may be formed by further performing electroplating after chemical plating. The metal of the plating layer 2 may be any metal that can be chemically plated on plastic and has good adhesion to the ceramic sprayed layer, but is usually nickel (hereinafter, a nickel alloy is included). Optimal. However, when nickel is used, nickel plating may be performed after copper plating in addition to the case where a nickel-only plating layer is used. Here, as the combination of the plating method and the plating metal, chemical nickel plating (including chemical nickel alloy plating) alone, chemical nickel plating followed by chemical nickel plating, or chemical copper plating followed by electric nickel plating ( (Including electric nickel alloy plating), and after chemical copper plating,
In some cases, electroplating is performed after chemical nickel plating. In any case, the first plating on the plastic substrate usually uses chemical plating.

When a metal plating layer is actually formed on a plastic substrate, it is usual that the surface of the plastic substrate is roughened before plating. The purpose of this roughening treatment is to improve the adhesion of the plating layer to the plastic substrate by the anchor effect. As a specific method of the surface roughening treatment, generally, a method of roughening the surface by wet chemical etching using a chromic acid-sulfuric acid type etching solution such as chromium trioxide-sulfuric acid or an alkali etching solution is generally used. However, a mechanical surface roughening treatment such as blasting or honing may be applied, and these may be used in combination. In this case, the surface roughening treatment is usually performed so that the surface roughness is about 5 to 20 μm as the maximum roughness.

Here, a typical process for forming a plating layer on a plastic substrate will be described as follows.

That is, first, the surface of the plastic substrate is washed by a known method, and then the surface is roughened by a chemical etching or a mechanical method as described above.
After chemical etching, the surface is neutralized. Next, depending on the type of plastic, conditioning is performed as necessary, and then as a catalyst for generating metal palladium nuclei serving as nuclei for chemical plating, a liquid containing palladium chloride, tin (II) chloride, and hydrochloric acid is used. An immersion treatment is performed, a reaction promoting treatment for activating metal palladium is performed, and then a chemical plating is performed. After the chemical plating, electroplating is further performed as necessary, and after cleaning, drying is performed. The electroplating may be performed according to a normal method. For example, in the case of nickel plating, strike plating is performed, and then semi-bright nickel plating or bright nickel plating may be performed.

The thickness of the metal plating layer is preferably in the range of 1 to 50 μm. If it is less than 1 μm, the effect of dispersing the heat at the time of thermal spraying and the heat at the time of use as a friction member cannot be sufficiently obtained, and the effect of preventing the sprayed layer from peeling off cannot be sufficiently obtained. If the thickness of the metal plating layer is less than 1 μm,
Roughening cannot be performed sufficiently in the roughening treatment after metal plating, and the underlying plastic base material may be locally exposed. On the other hand, forming a thick metal plating layer exceeding 50 μm only deteriorates economic efficiency. The thickness of the metal plating layer is most preferably in the range of 1 to 50 μm, particularly 3 to 50 μm. If the metal plating is performed only by chemical plating, the thickness should be up to about 10 μm. If the electroplating is to be performed after chemical plating, the chemical plating should be performed to about 1 to 2 μm before the electroplating to the required thickness. It is desirable to apply. When applying electroplating, it is desirable to keep additives such as brighteners to a minimum necessary amount in order to reduce the internal stress of the plating layer.

Although a ceramic sprayed layer is formed on the metal plating layer, it is desirable that the surface of the metal plating layer be subjected to a roughening treatment before spraying. The surface roughening treatment is performed to enhance the adhesion of the sprayed layer by the anchor effect, but the degree of surface roughening is set to 10 μm to the maximum roughness (Rt).
When the thickness is less than m, the effect cannot be sufficiently obtained. On the other hand, when the maximum roughness exceeds 50 μm, the thickness of the sprayed layer becomes non-uniform. Therefore, the degree of surface roughening is preferably in the range of Rt10 to 50 μm. , More preferably Rt10 to 30
It is within the range of μm. As a specific method of the surface roughening treatment, a mechanical surface roughening method is appropriate, but in some cases, a wet surface roughening method by chemical etching can also be applied. As the mechanical surface roughening method, a blast method in which hard fine particles are sprayed on the surface is optimal, but in addition, a method such as honing may be applied. In the case of blast, #
It is desirable to use about 100 to # 220 white alumina particles.

As the ceramic sprayed on the surface of the metal plating layer after the surface roughening treatment, inexpensive general-purpose ceramics, for example, alumina (Al ₂ O ₃ ) as the oxide ceramic,
Chromium oxide (Cr ₂ O ₃ ), silicon dioxide (Si
O ₂ ), titanium dioxide (TiO ₂ ), zirconia (Zr
O _2), zircon (ZrO ₂ + SiO ₂₎ or the like, titanium nitride as the nitride-based ceramics (TiN), silicon nitride (Si ₃ N ₄₎ or the like, carbide-based As the ceramic tungsten carbide (WC), chromium carbide (Cr ₃ C ₂ ), zirconium carbide (ZrC), titanium carbide (TiC) and the like can be used, and of course, a mixture of two or more of these may be used. Practically, a white alumina sprayed material (representative component: 98.5% of Al ₂ O ₃ , 1% of SiO ₂ ) mainly composed of Al ₂ O ₃ and a small amount of SiO ₂ added thereto, or Cr ₂ O ₃ a principal, and a small amount of chromium oxide-based thermal spray material with the addition of TiO ₂ or the like (representative component: Cr ₂ O ₃ 9
6%, a small amount of TiO ₂ 2%) or the like can be used.

If the thickness of the ceramic sprayed layer is less than 50 μm, sufficient wear resistance cannot be obtained. On the other hand, the greater the thickness of the thermal sprayed layer, the better the abrasion resistance. However, if the thickness is too large, the economy and the adhesion will be impaired.

As a specific thermal spraying method for ceramic thermal spraying, a ceramic sintered rod is melted in a high-temperature (about 3000 ° C.) oxygen-acetylene flame, and the droplets are accelerated in an air jet to spray. The so-called rowide spraying method, in which the target material is sprayed onto the target material, is most suitable, but a plasma powder spraying method or the like can also be applied. Note that this thermal spraying itself does not matter at atmospheric pressure or under reduced pressure.

The surface after thermal spraying is usually not smooth. Therefore, it is desirable that the surface after thermal spraying be smoothed to a maximum roughness of about several μm with a grindstone or a diamond abrasive, or to a maximum roughness of 1 μm or less depending on the application.

As described above, a wear-resistant member which is extremely lightweight and has excellent wear resistance can be obtained. Since the surface of the member is covered with ceramic having good corrosion resistance and electrical insulation, not only is the member excellent in wear resistance, but also excellent in corrosion resistance and electrical insulation.

[Table 2]

As shown in Tables 1 and 2, in the case of the member according to the present invention (the material of the present invention), the abrasion resistance is remarkably improved as compared with the case of using the plastic alone, and especially as the intermediate layer. It was found that when a nickel plating layer having a thickness of 20 to 30 μm was formed, the wear resistance was equal to or better than that of an aluminum alloy material on which a hard alumite film was formed.

Example 2 Instead of the chemical nickel plating in Example 1, except that a chemical copper plating was performed using a Melplate CU-390 manufactured by Meltex Co., Ltd. to form a copper plating layer on the base material. Applied the same base material and process as in Example 1. In this case, the same result as in Example 1 was obtained.

[0050]

Since the wear-resistant member of the present invention uses a remarkably lightweight plastic as a base material, the entire member is much more remarkable than a conventional wear-resistant member made of a light metal such as an aluminum alloy. Since it is lightweight and has a hard ceramic sprayed layer formed on the outermost surface, its wear resistance is as good as that of a conventional hard anodized aluminum alloy film. And since the metal plating layer is interposed between the ceramic sprayed layer and the plastic substrate, the heat during thermal spraying and the frictional heat when used as a wear-resistant member are not directly applied to the plastic substrate, It is dispersed in the plane direction by the metal plating layer, so that the heat of the spraying causes the surface of the plastic substrate to be carbonized and the sprayed layer is easily peeled off. The thermal spraying layer prevents the thermal spraying layer from easily peeling off, so the thermal spraying layer has sufficiently high peeling resistance, and sprays even when a large frictional load or high-speed friction is applied. The layer is less likely to be peeled off, and from this point, sufficient abrasion resistance can be exhibited.

In particular, when the metal sprayed layer is formed by roughening the surface of the metal plating layer, an effect of anchoring the sprayed layer to the ceramic is obtained, so that the adhesion of the sprayed layer becomes sufficiently high, The peel resistance of the layer can be sufficiently increased.
