により被覆した耐熱部材に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a thermal spray coating material having excellent heat insulation provided with heat resistance, which is used for thermal spray coating for improving the surface of ceramics and metals, and the like. Among the techniques for improving the high-temperature durability of heat-resistant components, the present invention relates to a heat-resistant member coated with these thermal spray coating materials by an optimal plasma spraying method, particularly as a component for a gas turbine or the like.

Above all, gas turbines exhibit higher efficiency as they are operated at higher temperatures, so that their operating temperatures are constantly required to increase. Therefore, materials that have both heat resistance and thermal shock resistance that can respond to it
Fine ceramics such as i 3 N 4 are being studied, but at present, gas turbine components are manufactured based on metal materials because of problems in impact strength.

る。However, the use of heat-resistant metal materials such as Ni-based and Co-based materials is limited to 1000 ° C. or lower. Therefore, when they are applied to gas turbine components, various methods for cooling or heat shielding have been studied. Heat shielding is to form a ceramic layer on the surface of a metal (hereinafter, referred to as a base material) of a high-temperature heat-resistant component such as a gas turbine, thereby lowering the base material temperature.
Conventionally, ceramic powder having low thermal conductivity, high thermal shock resistance and high emissivity has been used as a material for thermal spray coating.

O 2 and the like. However, even with thermal spray coatings obtained using this currently best thermal spray material, quenching,
In a gas turbine to which a rapid thermal cycle can be applied, the coating layer tends to peel off from the base material and lose its function. In addition, since these materials use rare earth oxides, if they are used alone, the price is high, and the sprayed materials produced are also very expensive, so they must be used in large quantities for structural materials for industrial use. Is quite costly.

部品等、種々の提案がなされている。In general, when a thermal spray coating is used under intense heat cycles of rapid heating and quenching, thermal distortion occurs between the base material and the coating, and it cannot follow the rapid thermal expansion of the base material, causing cracking and peeling of the coating layer. Does not show excellent durability. For this reason, various developments have been made on thermal spraying materials having not only low thermal conductivity but also a coefficient of expansion close to that of the base material. Further, a layer composed of a mixture or a composite of both is provided between the metal and the ceramic layer, which are the main causes of peeling (see, for example, JP-A-55-113880).
Etc.), or by forming fine cracks in the ceramic layer by heat treatment at a high temperature for a long time (see, for example, JP-A-56-54905).
Various proposals have been made, such as a component having a ceramic layer, and a component in which fine cracks are formed in the layer by quenching after forming the ceramic layer (for example, JP-A-58-87273).

きるからである。The development of a thermal spray coating material using magnesium silicate as a starting material was attempted for a ceramic material that is stable at high temperatures, has a high heat resistance effect, has a relatively large coefficient of thermal expansion, and can be manufactured at low cost. Magnesium silicate compounds include “MgO.SiO 2 ” and “2
MgO · SiO 2 ”and the like are known. However, MgO ・ SiO 2 is contained
Since the amount of SiO 2 is relatively high, the adhesion to the base material is deteriorated due to the poor leakage at the time of thermal spraying, and cracks are generated by applying a heat cycle. From these results, 2MgO · SiO 2 was selected as the magnesium silicate spray material. In order to further enhance the heat insulation and heat resistance effects, various studies have
ZrO 2 was selected, and a plurality of these were used in the thermal spray coating material of the present invention. The use of a plurality of materials having such heat resistance and heat insulation effects is because heat resistance and heat insulation superior to conventional heat insulation materials are exhibited, and a highly reliable coating layer can be formed.

に調整されたものが好ましい。Mixtures and composites can be used for 2MgO · SiO 2 , but it is effective to use pure mineral (forsterite). MgO · 4ZrO 2 also compounds, can be used composites and mixtures, compounds or composites spray granulated in a spray dryer or the like are preferable. The material of the present invention is adjusted to a particle size of 5 to 500 μm, particularly an average particle size of 10 to 100 μm.
It is preferable to adjust the temperature.
本発明について組成範囲を上記のように限定したもの
は以下の理由による。2MgO・SiO2が50重量%より多い場
合は熱膨張率が小さく母材の熱膨張率に追随できなくな
るばかりでなく、含有SiO2量が多くなるにつれ漏れ性も
悪く、剥離を生ずる。MgO・4ZrO2が80重量%より多い場
合は高温安定作用の低下が起こり好ましくない。本発明
溶射材料の粒径が5μm以下の場合は溶射ガンへ供給さ
れる粉の流れが悪く良好な被膜となりえず溶射時の歩留
りも低下する。また、500μm以上の場合は溶射被膜中
に未溶融粒子が形成され被膜の密着性の低下を招く。The reason why the composition range of the present invention is limited as described above is as follows. When the content of 2MgO · SiO 2 is more than 50% by weight, not only the coefficient of thermal expansion is too small to keep up with the coefficient of thermal expansion of the base material, but also as the content of SiO 2 increases, the leak property becomes poor and peeling occurs. If the content of MgO.4ZrO 2 is more than 80% by weight, the high-temperature stabilizing action is undesirably reduced. When the particle size of the thermal spray material of the present invention is 5 μm or less, the flow of the powder supplied to the thermal spray gun is poor, so that a good coating cannot be obtained, and the yield during thermal spraying also decreases. On the other hand, when the thickness is 500 μm or more, unmelted particles are formed in the thermal sprayed coating, and the adhesion of the coating is reduced.

義は大きい。The thermal spray material of the present invention is characterized in that two kinds of materials are combined, combined or mixed in various ratios. Thereby, the durability can be improved. Further, a coating obtained by spraying this material not only has excellent heat resistance and heat insulating properties, but also exhibits a hot expansion behavior similar to that of the base material. As a result, the present sprayed material which can suppress the peeling damage of the coating film has great industrial significance.

熱サイクル回数を調査した。結果を第1表に示す。The separation of the ceramic layer, which is the main cause of the shortening of the service life, is caused by thermal stress based on the difference in expansion coefficient between metal and ceramic.To alleviate this, various ceramics with a relatively large thermal expansion coefficient are selected to reduce thermal shock. The test was performed. The base material is a Ni-based alloy (IN939: Ni-Co-Cr-W alloy) of 50x50x5mm. After blast treatment with alumina powder, first, NiCrAlY alloy is 100μm reduced pressure plasma sprayed as a metal with high temperature corrosion resistance. Further, a sprayed material in which each ceramic shown in Table 1 was adjusted to an average particle size of about 30 μm was further plasma sprayed thereon. The obtained test piece was heated at 1200 ° C for 15 minutes,
It was subjected to a thermal shock test of cooling for 16 minutes, and the number of thermal cycles until crack initiation was investigated. The results are shown in Table 1.

Fig. 1 shows the No. 10 2MgO · SiO 2 -70wt% Mg which showed good thermal shock resistance.
The cross section of the film is shown using O.4ZrO 2 as a representative example. Many fine vertical cracks are present in the coating, and it is presumed that the thermal cracks have been improved by the vertical cracks.
