ABSTRACT:
A manufacturing method for depositing an Nb.sub.3 Sn layer on a niobium surface for high frequency applications comprising developing a tin vapor atmosphere which also contains a highly volatile tin compound in the gaseous state, and holding the portions of the surface which are to be provided with the Nb.sub.3 Sn layer at a temperature of between 900.degree. and 1500.degree. C for a predetermined period of time to form the Nb.sub.3 Sn layer permitting niobium surfaces of any shape to be provided with Nb.sub.3 Sn layers of high uniformity and quality.
