If the sliding member remains the sliding portion base material 5, for example, not only oxidative deterioration and corrosion will occur over time, but also abnormal wear and seizure will occur in the sliding portion of the link mechanism. A defect such as a defect occurs. Therefore, as a countermeasure against these, as shown in the example of FIG. 14, a method is adopted in which the grease 6 is provided to maintain the corrosion resistance of the base material 5 and at the same time avoid contact between the sliding members. In addition, as in the example of FIG. 15, the lubrication fine particles 8 and the hard particles 9 are co-deposited in the metal matrix 7 to improve the lubricity and wear resistance of the base material 5. The method is taken.
In addition, as in the example of FIGS. 16 and 17, by applying electroless NiP plating or coating and then heating and curing the plating film or coating, the corrosion resistance of the base material is maintained and at the same time the wear resistance is improved. The method to try is taken.

発生し、めっき膜が剥がれやすくなる。In the conventional manufacturing process, a steel material capable of quenching and tempering is subjected to quenching and tempering in advance, followed by plating, and then heat treatment for hardening the plating coating. FIG. 4 shows the relationship between the Vickers hardness of the electroless NiP plated film and the heat treatment temperature. From FIG. 4, it can be seen that, in terms of wear resistance, that is, the hardness of the coating film, about 400 ° C. is optimum for the heat treatment of the plating film. But,
As shown in FIG. 11, when the heat treatment is performed at 400 ° C., the base material is softened and a hard plating film is coated on the soft base material. Therefore, in a member to which a high load is applied such as a sliding member such as a link mechanism, the plating film is easily cracked and the plating film is easily peeled off.

度を上げることが出来ることがわかる。FIG. 5 shows the relationship between the hardening layer depth and the tempering temperature when the carburized and quenched chromium molybdenum steel 415 is tempered at a constant temperature for 4 hours. The hardened layer was defined as a layer having higher hardness than HV420. Also, FIG.
It can be seen from the results that when the tempering temperature is 300 ° C. or higher, the hardened layer is reduced. FIG. 6 shows the relationship between the hardness and the heat treatment time when the heat treatment temperature of the electroless NiP plated film is used as a parameter. Therefore, the softening temperature of the base material in this case is considered to be about 300 ° C. It can be seen from FIG. 6 that the plating film is sufficiently hardened even if the heat treatment time is applied even at a heat treatment temperature of 300 ° C. or less. For example, 200
It can be seen that if the heat treatment is performed at ℃, the plating film will be hardened after about 2000 minutes. Therefore, as in the manufacturing process shown in FIG. 3, if the carburized and hardened chromium-molybdenum steel 415 is electroless NiP plated and then the coated chromium-molybdenum steel is heat treated at 200 to 300 ° C. for a long time, It can be seen that the hardness of the coating can be increased without causing softening of the material.

る。In the conventional manufacturing process, a steel material capable of quenching and tempering is subjected to quenching and tempering in advance, followed by plating, and then heat treatment for hardening the plating coating. FIG. 4 shows the relationship between the Vickers hardness of the electroless NiP plated film and the heat treatment temperature. From FIG. 4, it can be seen that, in terms of wear resistance, that is, the hardness of the coating film, about 400 ° C. is optimum for the heat treatment of the plating film. As described above, the phenomenon that the electroless NiP plating film is hardened to the maximum at 400 ° C. is the same when the hard particles SiC are dispersed in the plating solution. However, as shown in FIG. 12, when the heat treatment is performed at 400 ° C., the base material is softened, and a hard plating film is coated on the soft base material. Therefore, in a member to which a high load is applied such as a sliding member such as a link mechanism, the plating film is easily cracked and the plating film is easily peeled off.

被膜の硬度を上げることが出来ることがわかる。FIG. 5 shows the relationship between the hardened layer depth and the tempering temperature when the carburized and quenched chromium molybdenum steel 415 is tempered at a constant temperature for 4 hours. The hardened layer was defined as a layer having higher hardness than HV420. Also, FIG.
It can be seen from the results that when the tempering temperature is 300 ° C. or higher, the hardened layer is reduced. FIG. 6 shows the relationship between the hardness and the heat treatment time when the heat treatment temperature of the electroless NiP plated film is used as a parameter. It can be seen from FIG. 6 that the plating film is sufficiently hardened even if the heat treatment time is applied even at a heat treatment temperature of 300 ° C. or less. For example, if the heat treatment is performed at 200 ° C., it can be seen that the plating film is hardened in about 2000 minutes. This phenomenon is the same not only for the electroless NiP plating film but also when hard particles are dispersed. Therefore, as in the manufacturing process shown in FIG. 8, carburized and quenched chrome-molybdenum steel 415 is subjected to electroless NiP plating in which hard particles SiC are dispersed, and then coated chrome-molybdenum steel to 200 to 3
It can be seen that the heat treatment at 00 ° C. for a long time can increase the hardness of the coating without softening the substrate.

めっき膜が剥がれやすくなる。In the conventional manufacturing process, a steel material capable of quenching and tempering is subjected to quenching and tempering in advance, followed by plating, and then heat treatment for hardening the plating coating. FIG. 4 shows the relationship between the Vickers hardness of the electroless NiP plated film and the heat treatment temperature. From FIG. 4, it can be seen that, in terms of wear resistance, that is, the hardness of the coating film, about 400 ° C. is optimum for the heat treatment of the plating film. As described above, the phenomenon that the electroless NiP plating film is hardened to the maximum at 400 ° C. is the same when the self-lubricating particles of tetrafluoroethylene polymer are dispersed in the plating solution. However, as shown in FIG. 13, when heat treatment is performed at 400 ° C., the base material is softened, and a hard plating film is coated on the soft base material. Therefore, in a member such as a sliding member such as a link mechanism to which a high load is applied, a crack easily occurs in the plating film,
The plated film is easy to peel off.

が出来ることがわかる。FIG. 5 shows the relationship between the hardened layer depth and the tempering temperature when the carburized and quenched chromium molybdenum steel 415 is tempered at a constant temperature for 4 hours. The hardened layer was defined as a layer having higher hardness than HV420. Also, FIG.
It can be seen from the results that when the tempering temperature is 300 ° C. or higher, the hardened layer is reduced. FIG. 6 shows the relationship between the hardness and the heat treatment time when the heat treatment temperature of the electroless NiP plated film is used as a parameter. It can be seen from FIG. 6 that the plating film is sufficiently hardened even if the heat treatment time is applied even at a heat treatment temperature of 300 ° C. or less. For example, if the heat treatment is performed at 200 ° C., it can be seen that the plating film is hardened in about 2000 minutes. This phenomenon applies not only to the electroless NiP plating film but also to the case where self-lubricating particles are dispersed. Therefore, as in the manufacturing process shown in FIG. 10, electroless NiP plating, in which self-lubricating particles of tetrafluoroethylene polymer are dispersed, is applied to carburized and quenched chromium molybdenum steel 415, and then coated chromium molybdenum steel It can be seen that the hardness of the coating can be increased without softening the base material by heat-treating at 200 to 300 ° C. for a long time.
