形成する。[0003] By casting, a projection is formed integrally with the base material using a wear-resistant cast iron material or the like. The projections 1 are formed on the base material A by a welding means such as arc welding, manual welding, MIG welding or the like using a high hardness welding material such as a high chromium type (see FIG. 7). A projection is formed on the base material by spraying a spray material such as a self-fluxing alloy. A paste obtained by adding a binder to a self-fluxing alloy powder is thickly applied to the surface of the base material, or is raised and heated at a predetermined temperature in a furnace in a vacuum, a reducing atmosphere, or an inert atmosphere. Thus, the self-fluxing alloy powder is melted or semi-molten to form an alloy layer that is firmly bonded to the base material, and a projection is formed on the base material using the alloy layer.

【発明が解決しようとする課題】しかし、従来の技術に
は以下のような問題がある。However, the prior art has the following problems.
【０００５】の方法においては、耐摩耗鋳鉄（例えば
高クロム鋳鉄）であっても、特に耐摩耗性を要求され
る、例えば摩砕用突起としては耐摩耗性が不十分であ
り、また、突起部のみに耐摩耗性が要求されるような場
合には適当でない。In the method (1), even abrasion-resistant cast iron (for example, high-chromium cast iron) is required to have particularly high abrasion resistance. This is not appropriate when only parts require abrasion resistance.

生しやすく、突起１の剥離、脱落のおそれがある。In the method described above, as shown in FIG.
Since irregularities of the bead b are formed on the surface of the projection 1 formed by the weld bead b, in the case of a grinding device or the like, the raw material is not easily slid and the driving load is large. Further, cracks t are likely to occur in the weld bead b, the bond portion (the portion c in the dashed line in the figure) and the heat-affected zone, and there is a possibility that the projection 1 may peel off or fall off.
【０００７】の方法においては、１ｍｍ以上の厚さに

して十分な高さが形成できない。また、溶射層は母材Ａ
との付着強度が小さく剥離しやすい。In the method described above, if the thickness is 1 mm or more, the deposited material is peeled off by thermal stress during thermal spraying, so that a sufficient height cannot be formed as a projection. In addition, the base material A
Adhesive strength is small and easy to peel off.

（ａ）から（ｂ）の状態）、局部的な２ｍｍ以上の厚さ
の肉盛りは困難である。In the method described above, if the build-up layer is thickened, the solvent (binder) volatilizes during heating and the volume decreases when the powder melts, so that pores are generated inside the build-up layer after cooling. There is. In addition, since the self-fluxing alloy a is fluidized and flows even in a semi-molten state during heating (the state from FIG. 8A to FIG. 8B), it is difficult to locally build up a thickness of 2 mm or more.
【０００９】そこで、この発明は、金属母材に、例えば

筋状突起を得ることを課題とする。Therefore, the present invention provides a continuous and stable streaky projection having a height of, for example, 3 mm or more, which is firmly bonded to a base material, has a smooth surface, and has high wear resistance. The task is to obtain

法は、高硬度で耐摩耗性が優れているうえに、母材と

上り状態が得られるからである。In order to solve the above-mentioned problems, the present invention first employs the above-mentioned method and basically builds up with a self-fluxing alloy powder paste. This is because this method has high hardness and excellent wear resistance, has a strong bonding force with the base material, does not easily peel off, and provides a smooth surface finish.

たのである。Next, when overlaying the self-fluxing alloy powder paste, a core material is arranged in the longitudinal direction of the streak to be obtained, and the core material is covered with the self-fluxing alloy powder paste. A ridge made of a self-fluxing alloy powder paste containing the core material is formed, and the ridge is heated to melt the self-fluxing alloy powder paste and bond it to the metal base material.

持される。The paste is generally made by kneading a powder with a binder, has a certain formability, and coats the core material with the paste, so that the coating shape is maintained. For this reason, when the self-fluxing alloy is heated to 900 to 1200 ° C. in a vacuum, a reducing atmosphere or an inert atmosphere, the powder becomes a molten or semi-molten state and flows with fluidity. The flow is suppressed as compared with the case without the core material shown in FIG. When the binder volatilizes, the volume of the self-fluxing alloy powder paste changes from a powder state to a molten state (see FIGS. 1B to 1C), but the self-fluxing alloy itself contains a core material. Is thinner than the height of the projection (Fig. 3 (c)).
), And vacancies rarely remain inside. For this reason, the covering shape of the ridge, that is, the shape of the streak-like projection is also kept high.

は確実に所要の高さ・形状のものを得ることができる。At the time of the heating and melting, if a partition material made of a refractory material is juxtaposed on both sides of the ridge, and then the heat treatment is performed, the flow of the molten alloy is prevented, and the streak-like projections are formed. The required height and shape can be reliably obtained.

列、複数段に敷き並べる。As the above-mentioned core material, various materials can be employed which keep their shape to some extent as long as the self-fluxing alloy powder is heated and melted. Generally, the core material has a higher melting point than the self-fluxing alloy and a higher hardness than the base material. Are preferred. The core material is
For example, if the self-fluxing alloy powder is made of the same composition as the cladding self-fluxing alloy obtained by heating and melting in vacuum, the melting point is higher than the powder, and the familiarity with the self-fluxing alloy that has been plated is also high. Good results are obtained with good wear resistance.
However, depending on the required wear resistance, a core wire of a high chromium-based hardfacing welding rod or other high hardness wire rod may be used. A diameter of about 3 to 7 mm provides good workability and quality. Further, the core material is laid in one to a plurality of rows and a plurality of stages at a position on the base material according to a required height and width of the projection.
