摘要： PURPOSE: To prepare a shadow mask base plate capable of obtaining a sharp image free from a doming phenomenon, by forging an invar type alloy having a face-centered cubic lattice structure and applying hot rolling to said alloy so as to allow a specific crystal surface to gather on a rolled surface.
CONSTITUTION: After an invar type alloy having a face-centered cubic lattice structure is forged, hot rolling is applied to said alloy so that 35% or more, pref., about 40% or more of an {100} crystal surface gathers on a rolled surface. Thereafter, cold rolling is applied to the rolled alloy plural times if necessary so that the draft in the cold rolling does not exceed 50%/one time and strong processing is further applied to prevent the crystal direction of the rolled surface from shifting from the {100} surface. The above mentioned draft is pref. set to 10W30%. Next, heat treatment of strain removing annealing is applied to attain the stabilization of the {100} crystal surface to obtain a shadow mask base plate capable of obtaining an image receiving tube free from a doming phenomenon by providing electron beam passing apertures at high density with high accuracy.

摘要： PURPOSE:To avoid occurrence of the reduction or the blockade for the aperture obtained by etching the iron plate by manufacturing the shadow mask for the color CRT with the material of the low carbon steel vacuum-fused. CONSTITUTION:The raw material is put into the dissolving tank and dissolved in vacuum to obtain the ingot of the low carbon steel. This ingot is then rolled out to obtain the iron plate of a fixed thickness. The photosensitive film is formed on both surfaces of the iron plate; the plate containing the pattern for the shadow mask is provided on the photosensitive film; and the aperture is formed through the etching. Then the plate is annealed in the hydrogen current and then pressed to obtain the spherical surface with the blackening process applied then. With this method, a high-cleanliness steel is obtained, and the obstacles extending toward the rolling direction can be reduced greatly when the iron plate of a prescribed thickness is obtained through the necessary rolling process. As a result, such defects can be prevented for the aperture obtained through the etching as the reduction, blockade and others.

摘要： PURPOSE:To form an oxidized film with little peeling off and excellent withstand voltage characteristics and capable of preventing the generation of rust by making the iron composition ratio of a shadow mask mainly composed of iron and nickel in excess of the original iron composition ratio and eliminating a gap in the boundary between the oxidized film and a basis material so as to form the oxidized film excellent in thermal stress. CONSTITUTION:By applying electrolytic polishing to a basis material mainly composed of iron and nickel, its surface is made to have excess iron in existence than the original iron composition ratio. This is caused by the fact that nickel ions on the metal surface layer are preferentially dissolved out and on the contrary anode-dissolved iron ions are deposited on the metal surface due to the difference of an anode dissolution speed and a diffusion speed between the iron ion and nickel ion. When an aimed oxidized film is formed on such an electrolytic polishing surface, the vicinity of the substrate approaches the state of the basis material mainly composed of iron, thereby its stress due to thermal expansion is applied via an intermediate layer and becomes comparatively gentle, thus obtaining a firm oxidized film with a sufficient thickness.
