    摘要: The present invention relates to a vacuum chamber and chamber parts made of aluminum or its alloys which exhibit excellent corrosion resistance to a corrosive gas or plasma introduced into the vacuum chamber, the surface treatment, and material for the vacuum chamber. The vacuum chamber has a porous layer with a structure in which a pore diameter at the top thereof is small, while a pore diameter at the bottom thereof is large. In order to give such a structure to the porous layer, a final anodizing voltage is set to be higher than an initial anodizing voltage when the surface of the base material is anodized. After the porous-type anodizing is completed, non-porous type anodizing may be conducted so as to grow a barrier layer. Furthermore, the base material made of aluminum alloy preferably has particles such as precipitates and/or deposits with a diameter of 10 .mu.m or less in average, and the precipitates and/or deposits are arranged in parallel with a largest surface of the base material.

    摘要: The present invention provides a method for forming an anode oxide film, in which on the assumption that a direct-current power source is used, a thick anode oxide film can be formed with good productivity within a short time without using special equipment. The method includes allowing a current A0 to pass through an aluminum base material, and includes a step of repeating a first electricity cut-off treatment multiple times, in which when a voltage reaches a voltage V1 during the formation of the film, the passage of electricity is once cut off, this electricity cut-off is continued for a period equal to or longer than an electricity cut-off time T1, and the passage of electricity is then resumed, wherein the voltage V1 and electricity cut-off time T1 satisfy the prescribed expressions.
