This paper reviews the development of contact materials for vacuum interrupters. During the
past 15 years, chromium-copper (Cr-Cu) has gradually become the dominant contact …

Copper-based materials have long been used for their outstanding thermal and electrical
conductivities in various applications, such as heat exchangers, induction heat coils, cooling …

Drawn from the author's more than four decades of practical experience in the industry, The
Vacuum Interrupter: Theory, Design, and Application first discusses the design and …

Vacuum interrupters are important components to ensure the safety of medium and high-
voltage power transmission, and contact material is an important factor affecting the …

CuCr alloys with Cr contents of 20 wt% and 25 wt% were prepared by selective laser melting
(SLM) using mixed powders. Microstructural evolution and effect of aging on the …

Cathode ablation is one of the dominant limitations for extending the maximum operating
time of arc heaters. In this work, the arc ablation behaviors and mechanisms of commercial …

A nanocrystalline surface layer was fabricated on the surface of CuCr8 alloy by surface
ultrasonic rolling treatment (USRT) with different rolling depth. The surface morphology …

In an increasing number of high-gradient linear accelerator applications, accelerating
structures must operate with both high surface electric fields and low breakdown rates …

The microcrystalline and nanocrystalline CuCr alloys prepared by high-energy ball milling
and hot pressing were investigated in this paper. The experimental results show that the …

A Cr-Cu surface alloy is synthesized using successive operations of Cr film deposition
followed by mixing in a melted phase with the Cu substrate by a low-energy, high-current …
