Abstract (en)
[origin: EP0655512A1] To achieve unitary (uniform) oxidic (oxidation) layers and defined surface properties, a process is provided for producing oxidic layers on metallic substrates subsequent to a nitridation (nitriding) or nitrocarburation process, in which the oxygen potential present in the oxidising atmosphere is continually determined, the measurement result is compared with a predetermined set value and, in the case of deviations, the oxidising atmosphere is modified until the measurement result agrees with the set value. <IMAGE>
