DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the improvement of rotating or vibrating electric shavers, and particularly aims to provide outer cutters with excellent wear resistance. [Background of the invention] The outer blades used in conventional electric razors are made of electroformed nickel or thin stainless steel sheets, so if used for a long period of time, they will discolor due to sweat etc. and the product value will decrease. do. In particular, sliding friction between the outer cutter and inner cutter may cause a solid solution layer to form between the two metals, and the area of the sliding surface increases due to wear.
As a result, there are disadvantages such as large frictional resistance, large sliding load, and increased power consumption. death,
To provide an electric shaver with excellent durability and low sliding resistance. [Summary of the Invention] In order to achieve this object, the present invention forms a zirconium nitride film on at least the sliding surface of the outer cutter and the inner cutter, and sets the composition molar fraction of the zirconium nitride film to nitrogen to zirconium. 0.3:1-0. This was achieved by setting the range of S:t. The zirconium nitride film can be produced by methods such as direct current sputtering, high-frequency sputtering, magnetron sputtering, ion beam sputtering, ion blating, CVD, and plasma CVD. A desired nitrogen content can be obtained by controlling the ratio of gas to nitrogen gas and the high frequency power.The nitrogen content can be controlled by controlling the ratio between the gas and the nitrogen gas.
□゛Especially when using the sputtering method, the total gas pressure of argon and nitrogen gas is preferably 0.003 to 0.3 Torr;
o, 'oo No discharge below 3 Torr, 0.3 T. Above rr, the discharge becomes unstable. Also, the high frequency power is 1
~5 W/ctA is desirable; below 1 W/cat, the precipitation rate is too slow and the efficiency is poor;
In this case, the deposition rate is saturated and does not increase at all, and the target temperature and substrate temperature only increase.
100~ from the viewpoint of malignancy such as reducing the mechanical strength of the material
A range of 50,000 is preferable; if it is less than 100 Å, the film will not be effective, and if it is more than 50,000 Å, the cutting edge will become rounded and the sharpness will deteriorate, which is not desirable. In particular, a range of 300 to 30,000 people is desirable. [Examples of the Invention] Examples of the invention will be described. Example 1 □ This figure 1 shows the high frequency span used in Example 1 of the actual can.
This is a schematic configuration diagram of the data storage apparatus. In the figure, 1 is an argon gas, 2 is a nitrogen gas, 3 is a heater, 4 is a substrate, 5 is a zirconium target, 6 is a high frequency power source, and 7 is an exhaust gas.・ . A predetermined number of outer blades 8 made of electroformed nickel blades are held on the substrate 4, zirconium is used as the target 5, and after reducing the pressure in the processing container 9 by the exhaust 7, the outer blades 8 are heated to approximately 156° C. by the heater 3. Heating, the output of high frequency power supply 6 is 3
A zirconium nitride film with a thickness of 0.5μ was created by sputtering while varying the gas pressure ratio of argon gas 1 and nitrogen gas 2 while keeping W/crA constant.
Outer blades were formed by changing the composition ratio of zirconium and nitrogen in this film. Example 2 Figure 2 is a schematic configuration diagram of a high-frequency ion brating device used in Example 2, where the same symbols as in Figure 1 indicate the same components, 10 is a high-frequency power source, 11 is a DC power source, and 12 is a high-frequency power source. 13 is a zirconium coil, 14 is an electron gun, and 5 is a processing device. As in Example I, the nickel electroformed outer blade 8 was held on the substrate 4, the output of the electron gun 14 was set to 5 KW, zirconium was evaporated, and the pressure of the argon gas was set to 1.5X IO-'
Tor'r, pressure of nitrogen gas 2 5 x 1O-5T
A zirconium nitride film with a thickness of '0, sμ was formed under the following conditions: high frequency power '3oow' and applied voltage 500cm.゛The molar fraction of nitrogen to zirconium in the film produced at this time was 0.
.. The ratio was 7:1. Comparative Example 1 Zirconium nitride was produced under the same conditions as in Example 2 except that the nitrogen gas pressure was changed to I x 10-' Tor. At this time, the molar fraction of nitrogen to zirconium in the nitride film is 1
:1. [Effects of the Invention] □ An electric shaver was assembled using the outer cutter produced above, the drive current was measured, and the results were compared with the measurement results of the drive current after further use for 50 hours. FIG. 3 shows the results of measurements made using i4mu with different ratios of zirconium and nitrogen. In FIG. 3, the horizontal axis shows the mole fraction, and the vertical axis shows the driving current. As can be seen from this figure, although the driving current decreases as the nitrogen content increases in the initial stage, after 50 hours of use, the Kino C fraction is 0.13 to 0. "8
The difference between the two values is good with little change compared to the initial one [J The drive current is large even when the nitrogen content is 0.2 or less or 0.9 or more. □ Also, when an electric razor was assembled using the outer cutter made in Example 2, and the drive current was measured in the same way, the initial value was 4jOmA-5, and after 0 hours of use, it was 480mA'. Ta.゛ □ ゛ □Next, the result of setting i in the same manner as in Konkeizaki'1i (the initial stage of 1' is 410
m'A and "small Z'tsu"*"i" 55 after 50 hours of use
It showed an increasing trend of 0 m^. In addition, although the above-mentioned example and comparative example both used a rotary dome-shaped outer cutter, it goes without saying that the same applies to a reciprocating type reticulated outer cutter. In addition, if a zirconium nitride film is formed not only on the sliding surface but also on the side that comes into contact with the skin, it will protect the nickel surface and prevent fading.
It has the effect of eliminating discoloration. Furthermore, although a nickel electroformed blade was used as the outer blade base material, the same effect can be obtained by using an electroformed nickel-cobalt alloy, stainless thin steel plate, or the like. As mentioned above, the molar fraction of nitrogen to zirconium is set to 0.3
:1~0. S:1, and by forming a zirconium nitride film on at least the sliding surface of the outer cutter, the increase in drive current is suppressed and the load current is held down even when used for a long time.
This provides an outer blade with a long life.
