摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a multi-layer ceramic shell mold with which in a lost wax casting method, the occurrence of surface defect on a casting product is prevented.
SOLUTION: The multi-layer ceramic shell mold which contains a wax master pattern for part to be produced or the other similar material and at least one contact layer as the other material is manufactured by passing through the following processes, that is; a process for forming the contact layer by dipping the master pattern into a first slip containing ceramic particles and a binder formed with mullite particles; a process for depositing sand particles onto the above contact layer; and a process for drying the above contact layer.

摘要： PROBLEM TO BE SOLVED: To provide a method which is a method for protecting a thermostructural part made of a CMC material against wear and is capable of overcoming disadvantages in the prior art and of providing especially high effectiveness.
SOLUTION: This method relates to a method for protecting a thermostructural part made of a ceramic matrix composite material against wear. In this method, for example, a coating is made by the steps of (a) providing a mixture comprising colloidal silica, a powdered silico-aluminous and/or aluminous refractory ceramic material, and water; (b) applying at least one layer of the mixture on the part; (c) drying the layer; and (d) placing the part at a temperature higher than 1,000°C to thereby firing the layer and form an enamel coating. This method is applicable to SiC moving flaps for a turbojet nozzle.

摘要： PROBLEM TO BE SOLVED: To provide a single-shell mold with which in a lost-wax casting method, regardless of a type of a columnar crystal structure directional solidification, a single-crystal structure directional solidification or an equiaxial solidification in this method can be used.
SOLUTION: This single-shell mold is manufactured by passing through the following operations, that is; an operation for forming a contacting layer, by which sand grains are deposited on a layer by dipping into first slip containing ceramic grains and binder, and the contacting layer is dried; an operation for forming an intermediate layer, by which the sand grains are deposited on the intermediate layer by dipping into second slip containing the ceramic grains and the binder, and the above intermediate layer is dried; and a reinforcing layer forming operation for repeating until the shell mold having a prescribed thickness is obtained, by which the reinforcing layer is formed by dipping into at least third slip containing the ceramic grains and the binder, and the sand grains are deposited on the layer, are performed. The ceramic grains in the slip, contain fire-resistant oxide or non-zircon fire-resistant oxide, and especially not at all contain a zircon in any layer.
