Tratamiento térmico en hornos de atmosfera de nitrógeno para piezas de equipos de radiofrecuencia

Abstract

Some parts of austenitic stainless steels

structures which must operate with

radiofrequency in ultra high vacuum need to

be machined with very high precision and need

to have a copper plating treatment. The heat

treatment for stress relief due to machining

proposed by the major research centres is

performed by vacuum furnaces, that do not

damage the structure of the material, but these

ovens are very complex and unusual, especially

for large pieces. To facilitate this process and

reduce its cost is proposed to realize in common

furnaces of inert atmosphere. But it is necessary

to perform the tests of intergranular corrosion

susceptibility and adhesion of copper, to validate

the change of the process.
