Zusammenfassung:The use of a composite coating of electrodeposited nickel and chromium to protect molybdenum from oxidation at 800 to 120 deg C exhibited certain practical limitations. Examination of the composite coating showed that the problems of blister formation, weakening of the bond between nickel and chromium, and edge separation were interrelated. Blister formation was eliminated and edge separation reduced slightly by an improved treatment of the chromium surface prior to nickel plating. The weakening of the bond between nickel and chromium appears to be iherent in the coating system.
