- Table 1 shows the result of evaluating the porosity of the thermal spray coating obtained by atmospheric pressure plasma spraying each slurry for thermal spraying under the conditions described in Table 2.
- the porosity was measured as follows. That is, after the cross section of the sprayed coating was resin-filled and polished, a cross-sectional image thereof was taken using a digital microscope VC-7700 manufactured by OMRON Corporation. And the pore part in a cross-sectional image was specified by the image analysis using image analysis software ImagePro made from Nippon Roper Co., Ltd., and the ratio of the area occupied in the cross-sectional image was obtained. “ ⁇ (good)” in the “Coating Properties No. 1” column indicates that the measured porosity of the sprayed coating was 10% or less, and “x (defect)” indicates that it was more than 10%. "-" Represents untested.

Abstract
Description
溶射用スラリー中のセラミック粒子は、平均粒子径が200nm以上5μm以下と比較的大きいために、溶射用スラリー中で重力により容易に沈降して沈殿を生じる。ただし、1Lの容積を有する高さ16.5cmの円筒容器内に溶射用スラリーを700mL入れて室温下で一週間静置したときに生じる沈殿は、20℃以上30℃以下の温度下、中心軸が水平となるように円筒容器を置いてその中心軸周りで円筒容器を100rpmの回転速度で120分間にわたり回転させて円筒容器内の溶射用スラリーを撹拌することにより消失する。このような特定の条件下で沈殿を消失させることができれば、溶射用スラリーは十分に実用に値すると言える。
したがって、本実施形態によれば、セラミック粒子の沈降によって生じる沈殿が実用上十分な再分散性を示す溶射用スラリーが提供される。
前記実施形態は次のように変更されてもよい。
次に、実施例及び比較例を挙げて本発明をさらに具体的に説明する。
