The present invention uses high melting point metals such as W and Mo, carbides and nitrides such as WC, VC, Mo 2 C, TiC, SiC, and Si 3 N 4 , and super heat-resistant materials such as Co-based and Ni-based materials in the Fe-based base material. Cu or Cu alloy powder containing one or more powders of oxides such as alloys and Al 2 O 3 is thermally sprayed and then pressed at high temperature with HIP to improve the resistance of the coating layer to peeling off from the boundary. At the same time, the denseness and mutual adhesion of the coating layer itself are improved, and the Cu alloy has good thermal conductivity and lubricity, and the above-mentioned high melting point metals, carbides, nitrides, Co-based, and Ni-based heat-resistant alloys have excellent heat resistance and wear resistance. A new composite jig that has the effect of improving seizure resistance and can be applied to sheet metal processing molds, bearings, sliding parts, die casting molds, etc., and provides excellent performance without causing wear, seizure cracks, etc. It concerns materials and their manufacturing methods. High melting point metals such as W, Mo, WC, VC, SiC,
Carbides and nitrides such as Si 3 N 4 , Co-based and Ni-based superalloys, and oxides such as Al 2 O 3 have excellent high-temperature strength, wear resistance, and corrosion resistance, so they can be used as plasma on the tool surface. There are examples of thermal spraying such as thermal spraying and gas spraying being used. However, the problem is that diffusion bonding to the base material is difficult to occur, and cracks may occur due to mechanical work stress or thermal shock during use, so it is not always fully utilized. In addition, Co-based and Ni-based superheat-resistant alloys have poor thermal conductivity, which also poses problems such as being susceptible to thermal shock cracking. The present invention uses an Fe-based alloy as the base material to be thermally sprayed,
Add the above W to Cu or Cu alloy powder as a thermal spraying material.
A mixture of powders such as Mo alloy carbides, nitrides, Co-based super heat-resistant alloys, Ni-based super heat-resistant alloys, Al 2 O 3 , etc. is thermally sprayed, and then pressurized at a high temperature of 850 to 1200 °C by HIP to form the boundary areas. Fe-based base material - W, Mo, WC, SiC, Cu or Cu alloy, or Fe-based base material
It improves the adhesion of Si 3 N 4 super heat-resistant alloys, Al 2 O 3 , etc., and also firmly holds the W, Mo carbides, nitrides, and super heat-resistant alloys in Cu, making it suitable for various cold and hot jigs. Used as a material, does not cause peeling, has good heat resistance,
The present invention relates to a new composite cold and hot tool material that combines wear resistance and seizure resistance to provide a long service life, and a method for manufacturing the same. Table 1 shows the combinations of the base material of the present invention material and the thermal spraying material,
Thermal spraying conditions, hot isostatic pressing conditions, and their effect on improving peeling resistance are shown. Comparative materials B', C', H', and K' are B, C, H, and
It is made from the same raw materials and the same thermal spraying method as K, but does not undergo HIP treatment. The number of thermal shocks before peeling is tested for each
For test pieces of 20mmφ x 10mmt that were thermally sprayed to a thickness of 2.0mm and those that were hot isostatically pressed after thermal spraying.
700℃ flame heating (20mmφ surface) strong wind cooling (20℃)
The thermal shock treatment was performed, and the number of repetitions until boundary separation occurred was determined, and the values of B', C', H', and K' were set as 100 and expressed as an index.

This is due to the effect of HIP treatment on improving bonding properties at the coating boundary and within the coating layer. Table 2 shows the results of the seizure resistance test at high temperatures for the materials of the present invention and comparative materials. The test pieces were cylindrical, and the end surfaces were thermally sprayed in the same way, followed by hot isostatic pressure treatment for the present invention material, and a comparison material that was not subjected to hot isostatic pressure treatment at high speed (1700 rpm). While rotating, the end face was brought into frictional contact with a polished steel material (S45C) to determine the limit load at which seizure would not occur, and the limit load for each comparison material was set as 100 and similarly expressed as an index. It can be seen that the critical seizure load of the material of the present invention is clearly large. This is due to the effect of strengthening the adhesion at the thermal spraying boundary, improving the mutual adhesion of the thermal spraying layers themselves, and
The temperature rise suppression effect on the friction surface is due to the excellent thermal conductivity of the densified sprayed layer containing the alloy.This is due to the lubricating action of Cu and Cu alloy.

The number of repetitions until seizure starts due to cracking when 20 gr of molten 18Ni-8Cr austenitic stainless steel at 1600°C is repeatedly dropped is expressed as an index, with the as-sprayed comparative material set as 100. It can be seen that the number of repetitions until the occurrence of seizure due to cracking is clearly large for the material of the present invention.

である。[Table] This shows the adhesion of the sprayed layer of the present invention material to the base material,
This is because the welding layer itself is dense and has high thermal shock resistance, making it difficult to cause heat cracks and peeling, and as a result, direct contact between the molten metal and the base material can be effectively prevented until the number of repetitions is higher. In addition, the material of the present invention has a higher thermal conductivity due to the densification of the sprayed layer containing Cu, so the thermal stress generated in the area where the molten metal is dripped is smaller, and therefore peeling is less likely to occur. This is due to the fact that direct contact with the base material was effectively prevented until a higher number of repetitions were reached. As described above, the present invention uses an Fe-based alloy as a base material, and in addition, high melting point metals such as W and Mo, carbides such as WC and VC, nitrides such as Si 3 N 4 , oxides such as Al 2 O 3 , Co base,
A mixture of Ni-based super heat-resistant alloy powder and Cu or Cu alloy powder is sprayed to improve the density of the sprayed layer itself.
Significantly improved mutual bonding properties, and excellent thermal conductivity due to the formation of a dense sprayed layer containing Cu.
The lubrication effect of the alloy prevents severe wear, seizure, thermal shock, and melting of molds and sliding parts for cold sheet metal processing, bearings, and molds for casting high-melting point metals, where seizure is a problem. The present invention provides a new composite tool material that is durable and has a long service life, and a method for manufacturing the same.
