摘要： PURPOSE:To obtain a light wt. printing wire having excellent abrasion resistance and high toughness, by providing an alloy layer based on nickel or cobalt to the surface of a wire main body based on a hard alloy powder containing titanium carbide. CONSTITUTION:A printing wire has a wire main body, which comprises a hard sintered alloy based on a hard alloy powder containing titanium carbide and containing at least one component selected from nickel and cobalt as a bonding phase, and an alloy layer, which is formed on the surface of the wire main body and based on nickel to which nickel phosphide or nickel boride was precipitated. or an alloy layer based on cobalt to which cobalt phosphide or cobalt boride was precipitated. The hard alloy powder containing titanium carbide contributes to the enhancement of the hardness and abrasion resistance of the printing wire. The bonding layer comprising at least one component selected from nickel and cobalt brings trouble to the wettability with the hard alloy powder or the particle growth of said alloy powder and contributes to a sintering property. The alloy layer, which is formed to the surface of the wire main body, comprising the hard sintered alloy imparts high toughness without bringing about the lowering in hardness.

摘要： PURPOSE:To improve fused carbonate corrosion resistance by surface-treating a pure metal or an alloy with an alkaline aqueous solution to form a film then lithium-treating this film. CONSTITUTION:A lithium compound such as lithium hydroxide or lithium alkoxide is dissolved or dispersed in water or an organic solvent such as alcohol. A liquid weakly acidized by hydrochloric acid, nitric acid, sulfuric acid, acetic acid, or phosphoric acid is prepared as required, the predetermined portion of a pure metal or an alloy applied with the alkali treating process is immersed in this liquid or coated with this liquid, thereby a paint film containing lithium is formed, then it is calcined. According to this lithium treating process, the film formed on the metal material surface in the alkali treating process is lithium-treated and becomes an oxide or a complex oxide of them and is stabilized. Thereby, the fused carbonate corrosion resistance on the pure metal or the alloy is improved.

摘要： PURPOSE:To increase the quality of images by using a material prepared by adding Mn to an Fe-Ni alloy to form the shadow mask, the frame and the inner shield and specifying the thermal expansion coefficient and the 0.2% proof stress of the material. CONSTITUTION:A material composed of Fe, 25-50wt% Ni and 0.8-10wt% Mn is used to form a shadow mask 6, a supporting frame 7 and an inner shield 9 interrupting the influence of earth magnetism, which are installed near the fluorescent screen 5 of a color picture tube. The thermal expansion coefficient of the material is adjusted to 20-80X10 and its 0.2% proof stress is adjusted to be at least 22kg/mm. . Besides, the surface of the material consists of a black oxide film with a spinel structure represented by the formula NixMnYFe3-X-Y. Accordingly, improved image quality can be realized by preventing color shift or similar phenomenon by inhibiting thermal strain. Furthermore, improved manufacture yield can be achieved by facilitating press formation performed at room temperature.
