Thermal-outgassing behavior of electrodeposited black chromium

The outgassing characteristics of electrodeposited black chromium were determined because of interest in using this coating in vacuum applications. Data obtained for a variety of conditions led to the conclusion that this coating is acceptable for use in optical-transport networks and plasma-physics experiments. The outgassing rate for an unbaked coating was 3 x 10/sup -10/ Torr liters/sec/cm/sup 2/.
