    • Provided is a method for carburizing a tantalum member whereby the tantalum member is less deformed by carburization and can be carburized with good flatness of the planar part thereof and in a uniform manner. The method is a method for subjecting a tantalum member 1 made of tantalum or a tantalum alloy and having a planar part 1a to a carburization process for allowing carbon to penetrate the member 1 from the surface toward the inner portion thereof and includes the steps of: setting the tantalum member 1 in a chamber 3 containing a carbon source by supporting the planar part 1a on a plurality of support rods 6 tapered at distal ends 6a thereof; and subjecting the tantalum member 1 to a carburization process by reducing in pressure and heating the interior of the chamber 3 to allow carbon derived from the carbon source to penetrate the tantalum member 1 from the surface thereof.
    • 提供了一种钽构件的渗碳方法,由此钽构件通过渗碳而变形较小,并且可以以均匀的方式使其平面部分具有良好的平坦度渗碳。 该方法是使由钽或钽合金制成的具有平面部分1a的钽构件1经受渗碳处理以使碳从表面向内部渗入构件1的方法包括以下步骤: 将钽构件1设置在容纳碳源的室3中,通过将平面部1a支撑在多个在其远端6a处成锥形的支撑杆6上; 并且通过降低压力并对室3的内部进行加热,使钽构件1进行渗碳处理,以使来自碳源的碳从其表面渗入钽构件1。

    • Provided is a method for carburizing a tantalum container which can easily control the carburization thicknesses of various portions of the tantalum container and carburize the tantalum container with a uniform thickness. A method for carburizing a tantalum container 1 made of tantalum or a tantalum alloy to allow carbon to penetrate the tantalum container 1 includes the steps of: supporting the tantalum container 1 on a support member 5, 6 provided in a chamber 3 and setting the tantalum container 1 in the chamber 3; and reducing the pressure inside the chamber 3 and heating the interior of the chamber 3, wherein a carbon source is placed in the vicinity of a portion of the tantalum container 1 hard to carburize.
    • 本发明提供一种能够容易地控制钽容器的各部分的渗碳厚度并以均匀厚度渗碳钽容器的钽容器渗碳的方法。 将由钽或钽合金制成的钽容器1渗碳以使碳贯穿钽容器1的方法包括以下步骤:将钽容器1支撑在设置在腔室3中的支撑构件5,6上,并将钽 容器1在腔室3中; 并且减小室3内的压力并加热室3的内部,其中将碳源放置在钽容器1的一部分附近难以渗碳。
