た。 (Industrial Application Field) The present invention relates to a sliding contact member having excellent wear resistance and used for the inner circumferential surface of an engine cylinder. (Prior Art) Cast iron materials containing a large amount of graphite as a lubricant, such as alloyed cast iron with a flaky graphite structure, are generally used as sliding contact members that require wear resistance, such as cylinder liners for automobile engines. It is well known that it is used. However, as engines become more powerful and rotate at higher speeds, sliding surfaces such as cylinder liners are exposed to high temperatures and high surface pressures, and the lubricity of graphite contained in cast iron materials alone causes the oil film to run out. As a result, problems such as wear, seizure, and scuffing occur. Therefore, as a countermeasure to these problems, a plating layer of high hardness, high melting point metal (e.g. chromium, etc.) is applied to the surface of the sliding contact member (see Japanese Patent Publication No. 18604/1983).
Alternatively, methods such as providing a sprayed layer, providing a ceramic sprayed layer, or surface hardening the steel material are often used. However, plated or thermally sprayed layers of hard metals or surface-hardened steel materials lack self-lubricating properties, resulting in poor wear resistance. There is a problem in that durability is poor due to poor adhesion with the contact member. In addition, there are products in which a composite plating layer is formed on the surface of the sliding contact member in which hard fine particles or self-lubricating fine particles are dispersed and co-deposited, but the composite plating method used in this case is complicated and lacks productivity. It contains the problem. Furthermore, there is a method in which silicon carbide is embedded into the surface of the sliding contact member to disperse and strengthen it using a mechanical method, but this method is very complicated and has poor productivity. (Purpose of the Invention) The present invention has been made in view of the points pointed out in the above-mentioned prior art section, and includes a highly hard substance (i.e., wear-resistant material) dispersed on the surface of cast iron in which self-lubricating graphite is dispersed. The purpose of this is to improve wear resistance and lubricity. (Means for Achieving the Object) As a means for achieving the above object, the present invention forms a large number of recesses dispersedly on the surface of a cast iron base material in which graphite is dispersed by a photoetching method, and fills the recesses with a hard wear-resistant material. (for example, chromium, etc.), graphite having self-lubricating properties and a hard wear-resistant material having excellent wear resistance are dispersed and mixed on the cast iron surface (i.e., sliding surface). Note that a plating method, a thermal spraying method, or the like is employed as a method for filling the recess with the hard wear-resistant material. (Function) In the present invention, the following effects can be obtained by the above means. That is, the graphite and the hard wear-resistant material dispersed and mixed on the cast iron surface (i.e., the sliding surface) significantly improve wear resistance and seizure resistance (i.e., lubricity). (Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG.
A hard wear-resistant material (for example, chromium, etc.) is placed in a large number of recesses 3, 3... formed by photoetching on the surface of the cast iron base material 1 in which flake graphite 2, 2... is dispersed.
4. That is, on the surface of the sliding member, graphite 2, 2... having self-lubricating properties and hard wear-resistant materials 4, 4... having excellent wear resistance are dispersed and mixed. Note that a plating method or a thermal spraying method is employed as a method for filling the hard wear-resistant material 4 into the recesses 3, 3, . . . . Next, a method for manufacturing this sliding contact member will be described in detail. As shown in Figure 2, the manufacturing process of the sliding contact member includes a polishing process A, a photoetching process B, a wear-resistant material filling process C (specifically, a plating process C1 or a thermal spraying process C2 ), and photoresist film peeling. It consists of process D and honing process E. The polishing process A is for reducing the surface roughness of the base material 1 (for example, a cast iron base material having a flaky graphite structure) as much as possible in order to maintain the machining accuracy of the next process, photoetching, and has an Rmax of 1μ. It is desirable that the surface roughness is as follows. In the photoetching step B, as shown in Figure 3, an ultraviolet-sensitive photoresist 5 (generally a negative resist is used) is applied to the surface of the base material 1 which has been degreased and cleaned using an alkaline degreasing solution or an organic solvent. A photosensitive agent coating step B 1 and the photoresist 5 surface are closely attached with a photomask 6 in which non-transparent parts 6a, 6a... are formed in a pattern corresponding to the recesses 3, 3... (see FIG. 1). a photomask adhesion step B2 , and an exposure step of irradiating the surface of the photomask 6 with ultraviolet rays using a light source 7 such as a high-pressure mercury lamp.
B 3 and a developing step B 4 in which the unexposed portion 5b that has not been irradiated with ultraviolet rays is dissolved and peeled off using a developer.
and an etching step B5 in which the surface of the base material 1 is etched and the portions not covered by the exposed portions 5a are etched to form recesses 3, 3. In the wear-resistant material filling step C, a hard wear-resistant material 4 (for example, , chromium, chromium carbide, etc.) by plating or thermal spraying. Thereafter, after peeling off the resist film 5a, a light honing process is performed to obtain a cast iron surface in which hard wear-resistant materials 4, 4, . . . are dispersed as shown in FIG. Next, specific examples will be described. Hard wear-resistant materials were dispersed on the surface of the cast iron base material shown in Table 1 below by the above manufacturing method (Invention Examples 1 and 2)
A wear test was conducted on Comparative Examples 1 and 2.

た効果がある。[Table] According to Table 2 above, it can be seen that Examples 1 and 2 of the present invention exhibit extremely superior wear resistance, lubricity, and seizure resistance compared to Comparative Examples 1 and 2. Although Comparative Example 1 shows the same lubricity as the inventive example,
Significantly inferior wear resistance. Due to the mechanical properties described above, the sliding contact member of the present invention is most suitable for use as a rotor housing of a rotary engine or a cylinder liner of a reciprocating engine. (Effects of the Invention) As described above, according to the present invention, graphite having self-lubricating properties (originally dispersed and contained in the sliding contact member) and hard wear-resistant material are dispersed and mixed on the surface of the sliding contact member. This has the excellent effect of improving wear resistance and seizure resistance, making it ideal for sliding contact members (for example, rotor housings, cylinder liners, etc.) of high-output, high-speed engines. Furthermore, since the hard wear-resistant material is filled in the recesses formed on the surface of the sliding contact member by photoetching, it has good adhesion and is sufficiently durable for long-term use. Furthermore, since the recesses filled with hard wear-resistant material are formed by photoetching,
The distribution pattern can be freely set, and the regularity of the distribution of the hard wear-resistant material on the sliding surface can be very easily ensured. Therefore, there is an excellent effect that wear resistance can be easily controlled.
