Manufacturing method of perforated plug |
| abstract |
A perforated plug having a thermal spray coating that is difficult to peel off is provided. A step of preparing a perforated plug having a thermal spray coating containing iron and iron oxide formed thereon, and a heat treatment step of holding the perforated plug at 400 to 550 ° C. for 5 to 60 minutes are provided. . When the heat treatment temperature is 400 ° C. or higher, the transformation from wustite to magnetite is promoted, and the iron ratio and magnetite ratio in the sprayed coating increase. If heat processing temperature is 400 degreeC-550 degreeC, the magnetite ratio and iron ratio which improve the adhesiveness with a plug main body will increase in a thermal spray coating. Furthermore, the tensile residual stress in the thermal spray coating is reduced. [Selection] Figure 2 |
