TL;DR: In this paper, the pore-blocking corrosion inhibitor and a lubricant coating having a liquid component were used to prevent corrosion and wear effectively, without significantly increasing contact resistance compared to untreated samples.
Abstract: The increasing reliability requirements for low-voltage electric contacts has led to a search for methods which could make gold plated surfaces impervious to the effects of atmospheric pollutants. The susceptibility of thin gold plate to corrosion is due both to its inherent porosity and its removal by wear. Because of these breaks in the plate, pollutants can attack the substrate metal or underplate to produce insulating corrosion products. The best methods were the application of a pore-blocking corrosion inhibitor and a lubricant coating having a liquid component. They 'inhibited corrosion and wear effectively, without significantly increasing contact resistance compared to untreated samples.

TL;DR: In this article, the ΔG effect was measured on pure Cu and Cu with 3·3 × 10−2 6·7 × 10 −2 and 10×10−2 at.
Abstract: The decrease of the rigidity modulus due to cold working, the so-called ΔG effect, was measured on pure Cu and Cu with 3·3 × 10−2 6·7 × 10−2 and 10 × 10−2 at. % Au respectively, as a function of deformation. The ΔG effect decreases with increasing Au concentration. Starting from simple assumptions, the length and density of dislocations can be estimated from the experimental results as a function of the degree of cold work.

11 Dec 1968TL;DR: In this paper, the authors propose a device for positioning the inner and outer rooms of a COAXIAL ELECTRICAL CONTACT ASSEMBLY RELATIVE to one another, and for locating the rooms in a proper position relative to a CRIMPING DEVICE.
Abstract: A DEVICE FOR POSITIONING THE INNER AND OUTER ELEMENTS OF A COAXIAL ELECTRICAL CONTACT ASSEMBLY RELATIVE TO ONE ANOTHER, AND FOR LOCATING THE ASSEMBLED ELEMENTS IN PROPER POSITION RELATIVE TO A CRIMPING DIE ASSEMBLY. A TUBULAR SLEEVE, FIXED IN POSITION RELATIVE TO A CRIMPING DEVICE, SERVES AS A GUIDE FOR A SLIDABLE BUSHING WHICH IS SPRINGBIASED TOWARD ONE END OF THE SLEEVE. FIXED, AS WELL AS REMOVABLE, STOP MEMBERS WITHIN THE BUSHING PROVIDE RELATIVE POSITIONING FOR INNER AND OUTER CONTACT ELEMENTS WHICH CAN BE INSERTED COAXIALLY INTO THE BUSHING FOR ASSEMBLY. A WINDOW APERTURE IN THE BUSHING WALL PERMITS VISUAL EXAMINATION FOR PROPER POSITIONING, AND THE SPRING BIASING ALLOWS DISPLACEMENT OF THE BUSHING BETWEEN ASSEMBLING AND CRIMPING POSITIONS.
