A viscosity measuring system is equipped with a tank, a flow pathway, an external force applying unit, and a pump. The viscosity measuring system further comprises a first pressure detection unit which detects a pressure of the electrode ink, and a second pressure detection unit which detects the pressure of the electrode ink on a more downstream side than the first pressure detection unit. A detection processing unit calculates a viscosity of the electrode ink based on the pressure detected by the first pressure detection unit and the pressure detected by the second pressure detection unit.

Viscosity measuring system

A raw material powder having particle sizes of not more than 125 &#x3bc;m and preferably not more than 75 &#x3bc;m, such as a powder of an alloy of Co-32% Ni-21% Cr-7.5% Al-0.5% Y is thermally sprayed onto surfaces of shroud members of a shroud to form a coating. The high velocity oxygen-fuel thermal spray method is used as the thermal spray method. In the obtained coating, the porosity is 5% to 30% by volume and the oxygen content is not more than 2% by weight. In particular, when the raw material powder has particle sizes of about 40 &#x3bc;m, it is possible to obtain the coating which has an extremely small oxygen content of about 0.5% by weight.
