In this case, although the density can be increased by performing additional treatment such as hot isostatic pressing (HIP treatment) on the sintered body, it is inevitable to increase the cost while greatly increasing the number of man-hours.

[0226] The heat-resistant member of the present invention can be applied to, for example, a supercharger member. A component for a supercharger to be described later is configured using the first embodiment of the heat-resistant component of the present invention, that is, an embodiment in which at least a part thereof is the sintered body of the present invention.

[0227] Examples of such supercharger components include a nozzle vane for a turbocharger, a turbine wheel for a turbocharger, a wastegate, a turbine housing, and the like. These supercharger components are required to have wear resistance because they are exposed to high temperatures for a long period of time and slide between other components in some cases. As described above, the sintered body of the present invention has excellent heat resistance and mechanical properties due to its high density. Therefore, a component for a supercharger that maintains excellent durability over a long period of time is obtaine...

[0242] The heat-resistant member of the present invention can be applied to, for example, a compressor blade as a member for a jet engine or a member for a power generating pulley. Such a compressor blade is constructed using the second embodiment of the heat-resistant component of the present invention, that is, an embodiment in which at least a part thereof is the sintered body of the present invention.

[0243] Figure 4 It is a perspective view which shows the compressor blade to which 2nd Embodiment of the heat-resistant member of this invention was applied. Figure 4 The illustrated compressor blade 2 includes an inner rim 21 and an outer rim 22 arranged concentrically with each other, and wing portions 23 arranged between these rims and arranged along the circumferential direction of the inner rim 21 . The inner rim 21 and the outer rim 22 each form a ring shape. Furthermore, the wing portion 23 is formed in a flat plate shape including a curved surface. Then, the wi...

Abstract

The invention provides metal powder for powder metallurgy, a compound, granulated powder and a sintered body. The metal powder for powder metallurgy according to the invention contains Co as a principal component, Cr in a proportion of 25 to 32 mass %, Ni in a proportion of 5 to 15 mass %, Fe in a proportion of 0.5 to 2 mass %, W in a proportion of 4 to 10 mass %, Si in a proportion of 0.3 mass % to 1.5 mass %, and C in a proportion of 0.05 mass % to 0.8 mass %, wherein when one element selected from the group consisting of Ti, V, Y, Zr, Nb, Hf, and Ta is defined as a first element, and one element selected from the group and having a higher group number in the periodic table than that of the first element or having the same group number as that of the first element and a higher period number than that of the first element is defined as a second element, the first element is contained in a proportion of 0.01 to 0.5 mass %, and the second element is contained in a proportion of 0.01 to 0.5 mass %.

Description

technical field [0001] The present invention relates to metal powder, compound, granulated powder and sintered body for powder metallurgy. Background technique [0002] In powder metallurgy, a sintered body is produced by molding a composition containing a metal powder and a binder into a desired shape to obtain a molded body, and then degreasing and sintering the molded body. In the production process of such a sintered body, atomic diffusion occurs between particles of the metal powder, whereby the molded body is gradually densified and sintered. [0003] For example, Patent Document 1 proposes a metal powder for powder metallurgy that contains Zr and Si, and the balance is composed of at least one selected from the group consisting of Fe, Co, and Ni and unavoidable elements. According to such a metal powder for powder metallurgy, sinterability is improved by the action of Zr, and a high-density sintered body can be easily produced. In recent years, such sintered bodies ...
