Method of preparing contacts and electrodes of electric vacuum apparatuses
First Claim
1. A method of preparing contacts and electrodes of electric vacuum apparatuses comprising the steps of exposing the surface of the contacts (electrodes) to a concentrated thermal flux of 104 to 106 W/cm2 in a vacuum or in the atmosphere of an inert gas and subjecting said surface to subsequent cooling, said concentrated thermal flux is applied for 21 to 100 ms and a rate of cooling during the cooling step is chosen to be within the range 104 to 106 K/s.
