まりが低い。(4) In the melting method, depending on the surface tension of the molten high-hardness powder, a large amount of high-hardness powder is required before melting, as shown in Figure 4 (A), or as shown in Figure 4 (B). If the amount of high hardness powder before melting is small, the processing allowance will be large and the yield will be low.

After mixing the powder of a brazing filler metal such as i-S i-B, Ni-P, etc., which has relatively high hardness and has a solid-liquid coexistence region of 50 °C or less so as to be homogeneous, wettability with the high-hardness material is determined. The object is achieved by a method of manufacturing a wear-resistant material, which is characterized in that the material is placed on a base material with a high temperature and then heated and bonded.

料が軟化することを防止できる。(Function) When using the above configuration, the high hardness material or particles such as WC are bonded to the base metal in a state where they are homogeneously distributed in the brazing filler metal melted on the base metal, but the brazing filler metal is bonded to the base metal. Its high wettability provides high bonding strength, its relatively high hardness provides wear resistance, and its narrow solid-liquid coexistence area prevents the formation of shrinkage cavities. Furthermore, since the melting temperature of the brazing filler metal is low, it is possible to prevent high hardness materials such as wc from softening.
