滑り性が良好で摩耗損傷が小さく、耐食性が優れている
ことが必要であるとされている。In general, electrical and electronic devices and their parts are manufactured using Ag or Ag alloys on the surface of a base material made of Cu or Cu alloy.
g-coated Cu material is used. All of these materials economically utilize the excellent conductivity, corrosion resistance, electrical connectivity, etc. peculiar to Ag, and many of them require stable electrical connectivity, especially for use in contacts. In order to stabilize electrical connectivity, it is said that it is necessary that the contact resistance be stable initially and over time, that the surface should have good slipperiness, little wear and tear, and excellent corrosion resistance.

性か比例しないようになってきた。It is known that when a corrosion film is formed, the electrical connectivity of Ag-coated Cu material deteriorates in proportion to the thickness of the corrosion film. Recently, due to the expansion of the scope of use of electric and 'r4 child devices,
As they have come to be used in complex and harsh environments, different corrosion films are formed due to the different usage environments, and corrosion resistance and electrical connectivity have become unequal.

。It is said that adhesion of mercapto compound (M) is effective as a discoloration and corrosion preventive agent for Ag or Ag alloys, but adhesion of M does not improve the contact resistance, slipperiness, frictional properties, etc. of Ag-coated Cu material. However, the electrical connectivity and slipperiness of the Ag-coated Cu material cannot be stabilized for a long period of time. Regarding the corrosion resistance of Ag-coated Cu materials, M coating cannot prevent corrosion of exposed parts of the base material due to diffusion of base material components due to heat treatment during the manufacturing process or damage to the Ag coating layer due to rolling etc. .

である。In view of this, as a result of various studies, the present invention has developed a surface treatment method for Ag ICU material that can provide long-term stable sliding characteristics and electrical connectivity to Ag-coated Cu material. A mercapto compound (M), a hydrocarbon (P), and a benzotriazole or its derivative (BTA) are added to the surface of the Cu or Cu alloy material coated with the alloy.

It is characterized in that it is applied as a solution mixed and dissolved in a solvent in the range of 1 to 10% BTAo and 01 to 10% BTAo.

上し、該材料の電気接続性を長期間安定させる。The liquid composition of the surface treatment method of the present invention has the above composition, and BTA adheres to the exposed parts of the base material due to heat diffusion generated on the surface of the Ag or Ag alloy-coated Cu material or to the exposed parts of the base material due to rolling damage. M adheres to the surface of the Ag alloy. Furthermore, although these types of adhesion do not improve the wear characteristics of similar metals,
P greatly contributes to improving wear characteristics. Moreover, by adhering M, P, and BTA to the surface of the Ag or Ag alloy-coated Cu material, corrosion resistance and wear characteristics are improved without deteriorating the surface quality, and the electrical connectivity of the material is stabilized for a long period of time.

済性の面から好ましくないためである。Therefore, the reason why we limited the Mffi that dissolves in the solvent to 0.01-5%, the amount of P to 0.001-10%, and the amount of BTA to 0.01-10% is because the corrosion prevention and lubrication effects are insufficient below the lower limits. This is because if the upper limit is exceeded, excessive adhesion will occur on the surface of the Ag-coated Cu material, making it difficult to remove and being unfavorable in terms of appearance, contact resistance, and economical efficiency.

The contact resistance (Re) was measured under the condition of 1 flow of 100 mA, and the initial friction coefficient (μk) and the change in the friction coefficient over time were measured using a Ballaten type tester. These results are shown in Tables 2 and 3 in comparison with conventional products.

Comparatively treated products kll cannot prevent deterioration of the friction coefficient (μk), and even if M and BTA are coated, the amount of M dissolved is smaller than the amount specified in the present invention, and the amount of dissolved M and BTA is lower. Comparatively treated product Nα12 in which the amount is greater than the amount specified in the present invention.
It can be seen that deterioration of the contact resistance (Rc) and friction coefficient (μk) cannot be prevented by the deterioration treatment in any case, and deterioration of the contact resistance (Rc) cannot be prevented in the comparatively treated product Nα13 with only P coating. In addition, although the comparison treated product Nα14 coated with M, BTA, and PFAP shows the same initial friction coefficient (μk) as the inventive treated product both before and after the deterioration treatment, the change in friction coefficient over time shows that the number of sliding cycles is 200. About 2
