Abstract

1390880 Oxidizing Cr-Ni alloys PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Dec 1973 [8 Dec 1972] 56316/73 Heading C7U [Also in Division H 1] A component of a discharge tube, e.g. a cathode, consisting of a Cr-Ni alloy is formed with a chromium oxide layer by heating in dry hydrogen, heating at 600 to 900‹C in air for 15 to 45 minutes, and then heating in moist hydrogen having a dew point of at least 13‹C. The component may be subsequently heated in air at 800 to 900‹C for 30 minutes.
