PRECISION-CASTING CORE, PRECISION-CASTING CORE MANUFACTURING METHOD, AND PRECISION-CASTING MOLD |
| 摘要 |
A coating layer including solely silicon alkoxide or mixed alkoxide of silicon alkoxide and aluminum alkoxide is formed on a surface of a sintered precision-casting core body mainly including silica particles so as to seal holes formed in the surface. As a result, it is possible to prevent the breakage of the core during casting. |
