“…Tin is a low melting point metal and is popular as a coating material due to its resistance to corrosion and tarnish. However, if tin is plated directly onto copper, inter-metallic phases readily form, even at room temperature, thus rendering the contact interface very brittle, highly resistive and susceptible to corrosion [2]. One way to overcome this is with the introduction of a diffusion barrier such as nickel.…”

The paper analyzes a technology allowing the improvement of such performance characteristics of contact joints as reliability and operating economy, with demountable contact joints taken as an example. The performance characteristics are improved through applying protective metal coatings based on low-melting alloys on the contact members working surfaces. The paper describes the process of alloys selection as well as the development in the technology of the material application onto the contact members.

Atlas is a 23 MJ pulsed-power facility presently in the design and construction phase at Los Alamos.[l] Atlas will be capable of delivering a damped sinusoidal current pulse with a peak current of 27-32 MA at 4 p. In the center of the Atlas machine, the current converges radially to a load through the powerflow channel which is a flat and conical transmission line. The current connections to the power flow channel are at a radius of approximately one-meter, where the maximum linear current density will be on the order of 51 W c m . The Pegasus II facility at Los Alamos has been used to provide peak currents of 5 MA in 6 p to test various types of current connections applicable to the connections for the Atlas powerflow channel. A total of 32 current connections, scaled to produce current densities and actions similar to Atlas conditions, were tested. Since the powerflow channel will be replaced after each shot, most of the connections were tested under single shot conditions.
