  • Process for forming passivated film
    Patent number: 5407492
    Abstract: A process for a passivated film which is far reduced in the amount of gas discharge and can desorb an adsorbed gas more readily, which process comprises heating a stainless member with a surface roughness, Rmax, of 1.0 .mu.m or less in an atmosphere of a mixture comprising oxygen gas and an inert gas and having a dew point of -95.degree. C. or below, an impurity concentration of 10 ppb or less and an oxygen content 5 ppm 25 vol % at 300.degree. to 420.degree. C.
    Type: Grant

  • Apparatus and method for oxidation treatment of metal
    Patent number: 5226968
    Abstract: A metal oxidation treatment apparatus to form the passivation film on the surface of the metal to be oxidized such as stainless steel or the like, comprising an oxidation furnace, a gas inlet to introduce gas into said oxidation furnace, a discharge outlet to discharge the gas from said oxidation furnace, and a heater to heat said oxidation furnace to the predetermined temperature, so that the metal to be oxidized is heated and oxidized in dry oxidation atmosphere while gas is passed in said oxidation furnace.
