METHOD OF MAKING CONTACTS OF VACUUM ARC-QUENCHING CHAMBERS Russian patent published in 2013 - IPC C23C26/00 H01H33/664

Abstract RU 2493290 C2

FIELD: electricity.

SUBSTANCE: powdered mixture and a workpiece of a high-electroconductivity material are placed in a vacuum chamber, where the powdered mixture is deposited in form of a coat on the workpiece by electron-beam deposit welding in a vacuum. Further electron-beam remelting of the entire volume of the fused coating is carried out in a single process cycle with deposit welding.

EFFECT: improved quality of contacts by obtaining a finer, uniform microstructure and low gas-content of the fused layer.
