Abstract: PURPOSE: A surface treatment method for improving erosion/corrosion resistance of cobalt-base alloys in liquid metal and a product manufactured thereby are provided to extend the service life of cobalt-base alloys by coating the product with boron. CONSTITUTION: A surface treatment method for improving erosion/corrosion resistance of cobalt-base alloys in liquid metal is as follows. A cobalt alloy material is formed by using cobalt-base alloys. The cobalt alloy material is casted and is cut. Organic and inorganic materials attached on the surface of the molded cobalt alloy material are eliminated. A thermal resistant sealed container is charged with the cobalt alloy material and powder and is closed. The powder and the cobalt alloy material are heated and are cooled in a furnace. The cobalt alloy material is coated with boron and is processed.

Abstract: PURPOSE: A jig for a drilling machine is provided to drill holes on work pieces of different sizes by holding/releasing a work piece regardless of the size of the work piece using a plurality of fixing units. CONSTITUTION: A jig for a drilling machine comprises a housing(110), a rotary handle(130), fixing units(140), and a fixing piece(150). The housing has a hollow hole(112) formed in the center of a body in which a rotary shaft(120) is inserted and a through hole(114) formed on a lateral side of the body. The rotary handle is integrally connected to the rotary shaft to rotate the rotary handle. The fixing unit is attached to or separated from the rotary shaft to hold a work piece. The fixing piece is inserted into the through hole of the housing to restrict the rotation of the rotary shaft rotating in the hollow hole of the housing.
Abstract translation: 目的：提供一种用于钻孔机的夹具，通过使用多个固定单元来保持/释放工件，而不管工件的尺寸如何，在不同尺寸的工件上钻孔。 构成：用于钻孔机的夹具包括壳体（110），旋转手柄（130），固定单元（140）和固定件（150）。 壳体具有形成在其中插入有旋转轴（120）的主体的中心的中空孔（112）和形成在主体的侧面上的通孔（114）。 旋转手柄一体地连接到旋转轴以旋转旋转手柄。 固定单元安装在旋转轴上或与旋转轴分离以保持工件。 固定片插入到壳体的通孔中，以限制在壳体的中空孔中旋转的旋转轴的旋转。

Abstract: The present invention relates to a method of manufacturing an insert screw, which includes: a core manufacturing step of supplying a mixture of metallic powders including a first metallic material with a binder into an injector to inject a core mold, removing the binder from the core mold, and sintering the core mold to manufacture the core; a screw manufacturing step of forging a second metallic material having strength lower than that of the first metallic material and manufacturing a screw body provided at an upper portion thereof with a fitting groove; and a bonding step of binding the core with the screw body after the core has been inserted into the fitting groove. As described above, according to the present invention, the binder is mixed with the metallic powders, and the mixture is injection-molded to manufacture the core. Thereafter, the core is bonded to the screw body subject to the cold forging process, so that the insert screw can represent higher strength and can be easily manufactured. Accordingly, the abrasion or the deformation of the head part of the insert screw cannot only be previously prevented, but also the manufacturing time of the insert screw can be reduced, so that the productivity of the insert screw can be remarkably improved.
