い。However, in recent years, super engineering plastics containing large amounts of minerals, metal powders, and other fillers have come into use, and there is a need for improved high-temperature performance, corrosion resistance, and wear resistance compared to conventional plastics. For these, industrial chrome plating on mechanical structural steel and nitriding on aluminum nitrided steel are not durable, so expensive die steel, maraging copper, etc. are currently used. However, even in this case, there are advantages and disadvantages in terms of corrosion resistance, wear resistance, and workability, and there are many problems.

るため、スクリュへの適用は一般的ではなかった。One measure to solve this problem is lining with corrosion-resistant and wear-resistant materials by conventional thermal spraying, but thermal spraying has weak adhesion because the bond with the base material is established by mechanical interlock. Since the interlayers are porous and allow the penetration of corrosive gases, the thermal sprayed layer may peel off during use, causing problems in general use. In addition, thermal spraying of self-fusing alloys involves torch fusing work after thermal spraying, but this involves high-temperature work, creating a poor work environment, causing distortion, and requiring high worker skills. Application to screws was not common.

。Next, to explain the second embodiment, when lining a screw with a corrosion-resistant and wear-resistant alloy or a mixture thereof as in the first embodiment, high-speed flame spraying is used instead of the thermal spraying method of the first embodiment. By obtaining a dense sprayed layer with excellent airtightness using the low-pressure plasma spraying method or low-pressure plasma spraying method, the sprayed layer itself becomes an airtight layer, so it can be directly hot isostatically pressed without canning. (e.g. 1000°C~12
Processing at a temperature of 00°C), it is possible to manufacture a screw in which the screw base material and the thermally sprayed lining layer are completely diffusion bonded.

2a is a corrosion-resistant and wear-resistant material such as stellite or tribaloy, and 2b is a self-fluxing alloy.

Therefore, the self-fluxing alloy itself can be used as a capsule, and the sprayed layer can be directly diffusion bonded to the base material without canning treatment.

By performing the treatment under the pressurized condition of t x 4 Hr, it is possible to deposit the Colmonoy #6 and alumina mixture on the screw base material and form a completely diffused Colmonoy lining.

肉盛法、鋳鍛品一体法に比べて低コストに製造できる。(Effects of the Invention) As explained in detail above, the lining screw of the present invention is produced by selecting various corrosion-resistant and wear-resistant materials according to the application, and thermally spraying them on the screw surface using various construction methods. After pre-treatment, a hot isostatic pressure treatment is carried out to form a thermal sprayed lining layer that is completely diffusion bonded to the base metal screw body and has also been diffused between the eyebrows. In manufacturing the lining screw of the present invention, the lining layer is made of various corrosion-resistant and wear-resistant materials, and a mixture of these materials can be used, and there is a large degree of freedom in selection, and the lining thickness can be arbitrarily selected, allowing for diversification. It is extremely effective for corrosion-resistant and wear-resistant applications. Also, in terms of cost, it can be manufactured at a lower cost than the full surface overlay method or the integrated casting and forging method.
