摘要： A niobium containing alloy amterial is initially annealed in a hydrogen atmosphere at a temperature approximating 700.degree. C. The alloy material is then immersed in an aqueous solution of approximately between 1.0%-20.0% by weight of sodium hydroxide being maintained at a temperature of at least 70.degree. C. Immersion of the alloy material in the aqueous solution removes niobium oxide which is formed in the surface portion of the alloy material during the annealing step. After removal of the alloy material from the aqueous solution, the alloy material is plated on its surface with an electric contact material.

摘要： In a rhodium electrical contact of a switch, particularly a reed switch, from 0.1 to 10 atomic % of Ag is included in the electrical contact. The electrical contact of the invention has a long life under a various loading conditions from a non-working condition, where an electric current is neither conducted nor broken by the switch, to a working condition, where erosion of the electrical contact is caused by short arcs between members of the electrical contact.

摘要： A switch is disclosed comprising two sets of rod-shaped fixed electrodes formed of a magnetic material and one cylindrical moving electrode formed of a permanent magnet, each set of the fixed electrodes being fixed to the respective end of a cylindrical vessel so that the ends of each set of the fixed electrodes face the ends of the other set of the fixed electrodes with the moving electrode capable of reciprocating between the ends of the two sets of fixed electrodes inside the cylindrical vessel. The moving electrode is comprised of at least one adhesive layer of a metal selected from the group consisting of silver, nickel, copper and alloys thereof on the surface of the permanent magnet, and at least one contact layer of a metal selected from the group consisting of rhodium, wolfram, rhenium, ruthenium and alloys thereof, silver-wolfram, gold-chromium on the adhesive layer of metal. At least the permanent magnet of the moving electrode and the adhesive layer of metal are thermally diffused with each other.

摘要： Electrical contacts are produced by processes comprising (1) forming on a metallic body a first layer of low melting metal(s) and (2) forming on the first layer a second layer of high melting metal(s). The thus produced contacts possess prolonged life, approximately 10 times that of conventional contacts when they are operated as working contact.
