Definitions
- the thickness data of the first layer and the middle part of the contact specimen were obtained from the hardness curves of five pieces by the above procedure, and the obtained five data were arithmetically averaged. Ask for it.
- the thickness data in the examples described later is the arithmetic average value.
- the hardness of the first and second layers of the contact specimen was obtained by taking the minimum measured value of the first layer and the maximum measured value of the second layer from the five hardness curves in the above procedure. Arithmetic average of the five data obtained.
- the average hardness in the table of the examples is the arithmetic average value.
- Specimen 34 was prepared under the same conditions as the above specimens except that the annealing temperature and time during the rolling process were respectively set to 7500 (5 hours). Intermediate portions with thicknesses of 190 / zm and 230 ⁇ m were formed in Samples 3 and 34.
- Sample 35 was published in Japanese Unexamined Patent Publication No. 61-114144, Sample 3 Sample No. 6 is a sample prepared according to the method described in each of Japanese Patent Publication No. 58-189913. Sample 35 is the first sample having the chemical composition shown in Table 1. The Ag alloy of the layer and the second layer was prepared by melting, hot pressing and rolling, and then internally oxidized under the same conditions as above.
- Example 3 A composite electrical contact having the same chemical composition as both samples 1, 2, 4, 5, and 6 in Table 1 was produced.
- the second layer was formed in the same manner as in Example 1, and the first layer was formed thereon by a vapor deposition method.
- a material having the same chemical composition as that of the second layer was formed in the same manner as in Example 1, except that a thin pure Ag layer was hot-pressed on one surface and hot-pressed. .
- each material was placed in a vacuum chamber with the pure Ag layer on the back side, and then the first layer was formed on the front side as follows.
- a target with the same chemical composition as the first layer of samples 1, 2, 4, 5, and 6 in Table 1 was prepared.
