Conventionally, in order to meet such requirements, porous chromium plating has been applied to the surface of parts, which has been widely used because it has a high melting point, high hardness, excellent corrosion resistance, and retains lubricating oil appropriately. However, the current situation is that, among the recent requirements for materials, properties that satisfy the wear resistance, particularly abrasive wear resistance, have not been obtained.

In order to meet these demands, many attempts have been made to form thermal spray coatings on the surfaces of metal materials to improve wear resistance, corrosion resistance, and lubricity. Conventionally, thermal spray materials include various metal powders, oxide powders, and composite powders thereof, depending on the characteristics required for the coating. Among these thermal spraying materials, metals such as molybdenum, cobalt, and nickel have the hardness, wear resistance, and corrosion resistance that can be used for mechanical parts, and can provide a good thermal sprayed surface finish. There are self-fusing alloys mainly composed of nickel and chromium, various cermets, and ceramic materials such as chromia and titanium carbide. However, the ceramic sprayed materials currently in use have the disadvantage that although they have high hardness, they are brittle and wear out significantly in environments where high loads and impacts are applied. Furthermore, among various metal materials, molybdenum and self-fusing alloys are easy to thermally spray and have excellent performance, and have obtained fairly good results in terms of relative wear. However, in terms of oxidation resistance and wear resistance at high temperatures, they cannot withstand the harsh conditions imposed on modern internal combustion engines, and even better wear resistance and seizure resistance are required.

The present invention uses chromium (-iron carbide ((Cr, Fe)7C3) in ferrochrome, which has high hardness and is inexpensive, as a hard phase component that contributes to wear resistance, and overcomes the drawbacks of chromium-iron carbide. In order to compensate for the lack of toughness, we mixed stainless steel, which has low hardness but excellent toughness and good corrosion resistance, with a self-fusing alloy that has medium hardness and toughness as a binder phase component, and created a chromium-based alloy. This prevents the occurrence of cracks caused by the lack of toughness of carbide, making it possible to obtain a tough thermal sprayed coating with excellent wear resistance and corrosion resistance.For example, the high carbon ferrochrome (FCrH) and molybdenum Although the coating made of thermal sprayed material (No.) had high hardness, it lacked toughness and had poor wear resistance under heavy loads.
Low carbon ferrochrome (FGrL) and FGrHlMO and F
Similarly, coatings using a thermal spray material made of CrI had problems in wear resistance due to lack of toughness. That is, it is necessary to use some kind of binder phase to prevent the particles from falling off due to insufficient toughness of the hard, wear-resistant phase. The tendency for wear-resistant particles to fall off due to lack of toughness is greater in highly hard materials, and this also depends on the original properties of the material.

Alternatively, abrasive wear increases.

On the other hand, in order to improve these points, there are also attempts to use a self-fusing alloy phase as a binder component.

The self-fusing alloy phase has a hardness of Hma; 400 to 600, and the alloy itself has good toughness, but since the melting point is low and the strength is high, the tension of the sprayed coating is large and the bonding force between particles is weak. Therefore, when observing the coating on the sliding friction surface, in MO and FCrH, the fracture due to cracks progresses within the individual particles of the coating and it falls off, but in the case of self-fusing alloys, the units of this fracture are large, and it does not occur under heavy loads. Shedding is greater. In other words, significant wear occurs under sliding friction under heavy loads.

In order to eliminate the above-mentioned drawbacks, the present invention uses a stainless copper phase as a binder phase, which has a relatively low hardness of Hv = 200 to 400, but has excellent toughness, and has a relatively low tension within the film. By using a self-fluxing alloy having toughness of about 400 to 600, the wear resistance under heavy loads is improved.

The thermal spraying material of the present invention includes 40-80% by weight of ferrochrome powder, 10-50% by weight of stainless steel powder, and 1% by weight of self-fusing alloy powder.
The composition is 20-60% by weight of chromium, 5-51% by weight of nickel, 1.3-7% by weight of carbon, and 0.5-7% by weight of silicon.
, 0.1 to 2.0% by weight of boron, with the balance being iron and incidental impurities. In this case, carbon must be included as a carbide of chromium and iron, and chromium or nickel must be alloyed with iron.

Carbon forms carbide with chromium φ iron and contributes to wear resistance, so if carbon is less than 1.3% by weight, carbide is insufficient, resulting in low hardness and poor abrasion wear resistance.
If the carbon content is 7% by weight or more, there will be too much carbide and the film will become brittle.

Since chromium exists as chromium-iron carbide and also forms an alloy with iron and contributes to improving toughness, it is necessary to include the total amount in an amount of 25 to 62% by weight. chrome is 2
If it is less than 5% by weight, the hardness will be insufficient and the lapping wear resistance will deteriorate, and if it is more than 62% by weight, it will become brittle.

The preferred composition range is 5 to 51% by weight of nickel, 0.5 to 7% by weight of silicon, and 0.1 to 2.0% by weight of boron, which is limited by the amount of self-fusing alloy.
