Abstract: A PROCESS FOR PLATING AN ARTICLE WITH A SILVER-PALLADIUM ALLOY COMPRISES THE STEPS OF: PROVIDING THE ARTICLE WITH A CONVENTIONAL SILVER STRIKE, ELECTROPLATING THE ARTICLE IN A SILVER CYANIDE SOLUTION AT A CURRENT DENSITY OF ABOUT 10 AMPERES PER SQUARE FOOT FOR ABOUT 20 MINUTES, ELECTROPLATING THE ARTICLE IN AN AGITATING PALLADIUM CHLORIDE AND AMMONIUM CHLORIDE ACIDIC SOLUTION AT A CURRENT DENSITY OF ABOUT 4 AMPERES PER SQUARE FOOT FOR ABOUT 8 HOURS, AND HEATING THE ARTICLE AT A TEMPERATURE OF ABOUT 300 TO 400*C. FOR ABOUT 8 HOURS TO ALLOY THE SILVER AND PALLADIUM THEREON.

Abstract: The outwardly flanged end of a glass tube is hermetically sealed by means of a pure or indium coated aluminum wire gasket which is squeezed at a pressure of about 5,000 pounds per linear inch of wire between the glass flange and a metal closure plate and heated to about 482*F or above. The pressure is applied by Cclamps which grip the closure plate and a split ring collar surrounding the tube. An aluminum cushioning gasket is disposed between the collar and the glass flange to prevent glass fracture. Steel spacer shims surround both gaskets to prevent extrusion of the gaskets under pressure.
