摘要：
lThe process of local softening of functional surfaces of an elastic sea] from bronze BrB2 is studied with the aim of creating a soft layer on the tightening surface, which should perform tightening and protective functions. The softening is provided by electron beam treatment (EBT) of the surface layer. The equipment for the EBT is chosen; the properties and the microstructure of the bronze are studied as well as the variation of the microstructure over the thickness and the width of the softening layer. The tightness of seals serving in simulators of detachable joints is determined.
