Definitions
- FIG. 1 is a longitudinal sectional view of a piercer plug 10 according to an embodiment of the present invention.
- the piercer plug 10 includes a plug body 11 and a thermal spray coating 12.
- the iron-based alloy in the thermal spray coating 12 is mainly composed of iron (Fe) and contains carbon (C), silicon (Si), manganese (Mn), chromium (Cr), and the like.
- the iron-based alloy in the thermal spray coating 12 may contain only a part of C, Si, Mn, and Cr, or may contain elements other than C, Si, Mn, and Cr.
- the chemical composition of the iron-based alloy in the thermal spray coating 12 may not be microscopically uniform. For example, microscopically, a portion that hardly contains Cr and a portion that has a high Cr content may be mixed.
- the oxide in the thermal spray coating 12 is an oxide formed by oxidizing the iron-based alloy.
- Specific examples of the oxide in the thermal spray coating 12 include iron oxide and a composite oxide of iron and chromium.
- the iron oxide include FeO and Fe 3 O 4 .
- the composite oxide of iron and chromium is, for example, (Fe, Cr) 3 O 4 .
- the oxide in the sprayed coating 12 may contain a metal oxide other than the above.
- the ratio of the oxide in the thermal spray coating 12 is not limited to this, but is preferably 25 to 80% by volume, more preferably 35 to 65% by volume. Moreover, it is preferable that the ratio of a metal component is high in the vicinity of the plug main body 11, and the ratio of an oxide becomes high as it goes to the surface. According to this configuration, the adhesiveness with the plug body 11 can be further increased.
- the volume ratio of the oxide can be calculated from cross-sectional observation of the sprayed coating 12.
- thermal spray distance The longer the distance from the tip of the thermal spray gun 21 to the surface of the plug body 11 (hereinafter referred to as “thermal spray distance”), the higher the ratio of oxide in the thermal spray coating 12. This is because the oxidation of the metal sprayed from the tip of the spray gun 21 proceeds according to the spray distance.
- the spraying distance is not limited to this, but is, for example, 100 to 1400 mm. Further, by spraying while gradually increasing the spraying distance, the ratio of the metal component in the vicinity of the plug body 11 can be increased, and the ratio of the oxide can be increased toward the surface.
- the thickness of the sprayed coating 12 is not limited to this, but is, for example, 200 to 3000 ⁇ m.
- the piercer plug 10 according to the embodiment of the present invention has been described above.
- the XRF-Cr concentration of the thermal spray coating 12 is 3 to 20% by mass. Thereby, the wear resistance of the piercer plug 10 can be further improved.
- the thermal spray coating 12 can be formed by, for example, plasma spraying, flame spraying, high-speed flame spraying, or the like.
