する。Plasma transfer welding (PT) is performed using a homogeneous mixed powder of metal powder and ceramic powder as a weld overlay material.
It is not possible to form a build-up layer (composite weld build-up layer) having a composite structure consisting of a metal matrix and ceramic particles mixed as a dispersed phase in the matrix on the surface of a structural member by a welding method such as A welding). It is publicly known. This composite weld overlay has high strength, high wear resistance, high heat resistance, etc. due to the dispersion-strengthening effect of ceramic particles, as well as the characteristics of IJ socks, such as toughness, and also has other methods such as Unlike build-up layers formed by thermal spraying, the bonding at the interface with the base material is strong, so it is effective as a protective layer for the surfaces of various structural members, such as rolls and sliding parts. It is highly effective in improving stability and durability.

たブローホールは、構造部材の重大な欠陥であることは
言うまでもない。Although the welded composite build-up layer is an excellent protective layer that has wear resistance, strength, toughness, etc., the build-up layer often contains weld defects such as blowholes. In addition, composite build-up layers have lower toughness than ordinary metal build-up layers and are more prone to high-temperature cracking during welding, so the base metal surface must be preheated to approximately 300°C or higher to prevent hot cracking. Since welding is generally performed, it can be said that the environment is such that blowholes are likely to occur in the composite overlay. It goes without saying that blowholes that occur in the built-up layer are serious defects in structural members.

して用いることにより好結果を得ることができる。There are no particular restrictions on the materials of the metal powder or ceramic powder or the blending ratio of the two in the composite powder welding material of the present invention, and the material properties of the composite overlay layer are required depending on the application and usage conditions of the target structural member. This will be determined as appropriate. An example of the metal powder is 25Cr-2O
Ni-Fe steel (JIs 5US310 equivalent), 18C
r-8Ni-Fe steel (JIS 5US304 equivalent)
, 17Cr-12Ni-Fe steel (JIS 5US3
16 equivalent), iron-based alloys such as 15Cr-16Mo-3,3
Ni-based alloys such as W-5,5F e-N i (equivalent to Hastelloy C), or 27Cr-17Ni-40Co
-Fe, or 28Cr-4W -IC-3Fe-Co
Co-based alloys such as (equivalent to Stellite 6) can be mentioned. Examples of the ceramic powder include silicon carbide, chromium carbide, and the like, as well as titanium carbide, tungsten carbide, and the like. In addition, as is well known, there is a clear correlation between the material properties of the composite overlay layer that is formed, and the mixing ratio of the ceramic powder The higher the amount, the higher the hardness and abrasion resistance of the composite overlay layer, but on the other hand, the toughness etc. will decrease.In general, considering the balance of these properties, the blending ratio of ceramic powder is is about 5~
It is adjusted to a range of 95% by weight. In the present invention as well, the blending ratio can be arbitrarily determined depending on the requirements for the material properties of the intended composite overlay layer. The particle size of the powder is not particularly limited, but from the viewpoint of weldability and prevention of component segregation in the build-up layer, a range of about 50 to 300 μm is appropriate, and in the case of fine powder, as shown in the examples. Good results can be obtained by granulating it into granulated powder.
