Title:
VESSEL FOR MOLTEN METAL AND ITS SURFACE TREATMENT
Document Type and Number:
Japanese Patent JP3383592
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a surface treatment coating film excellent in property of absorbing or diffusing a gas generated from a molten metal and to provide a surface structure of a vessel contributing also toward upgrading a product casting.
SOLUTION: A thermally sprayed dense metallic coating film is formed on the surface side of a substrate by thermally spraying a heat resistant alloy comprising a combination of two or more selected from Ni, Co, Cr, Al, Y and Ta and a thermally sprayed porous ceramic coating film is formed as a top coat on the surface side by thermally spraying a powdery ZrO2 mixture prepd. by adding 1-5 wt.% pure ZrO2 without contg. a stabilizing component and/or 2-20 wt.% unstabilized ZrO2 contg. <5 wt.% stabilizing component to stabilized or partially stabilized ZrO2 contg. 6-30 wt.% stabilizing component as a main component to obtain the objective vessel for a molten metal.
