New technology of ion-plasma modification of the contact surfaces of reed switches in oscillatory discharge

The iron-nickel contact surfaces of reed switches after ion-induced modification have been studied using methods of Auger-electron spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy, and optical microscopy. It was demonstrated that the corrosion stability and erosion resistance of the modified contacts is associated with the features of surface topography as well as with a formation of nitride layers. Experimental grounds for a production possibility of reed switches with the modified contact surface instead of electroplating based on the precious metals are given.
