摘要:
A thermal barrier coating method forms a thermal barrier coating by spray coating over the surface of a component where cooling holes are made. The thermal barrier coating is formed by spray coating after masking pins, which do not protrude above the surface of the component, are inserted into the cooling holes or masking pins protruding above the surface of the component are inserted and get shrunk due to heat while spray coating, obtaining the protruding amount equal to or less than the thickness of the thermal barrier coating after shrinkage, which characterizes the method. By way of this method, a thermal barrier coating can be formed all over the surface without clogging the cooling holes.
摘要:
A thermal barrier coating enabling to prevent peeling of layer in a high temperature use and still having a high thermal barrier effect, a turbine part coated by this thermal barrier coating and a gas turbine comprising this turbine part are provided. The thermal barrier coating comprises a base material 21 of high temperature heat resistant alloy and a ceramics layer 23 formed on the base material 21. The ceramics layer 23 comprises ZrO2 added with Yb2O3 as stabilizer and is laminated on the base material via a bond coat layer 22 laminated as a metallic bond layer. A plurality of cracks 23A are preferably introduced in the ceramics layer 23. The turbine part is constructed having its surface coated with the above thermal barrier coating.

摘要:
A tip of rotor blade which rotates is an abradable surface. An inner wall of a shroud as a jacket for the rotor blade is an abrasive surface. A part of an abrasive particle protrudes from the abradable surface. When the tip of the rotor blade which rotates contacts the inner wall of the shroud, the protruding section of the abrasive particle slides with the abrasive surface so as to be ground. By doing this, a turbine which can maintain an appropriate clearance between the rotor blade and the shroud and can be used for a long period under high-temperature conditions with easy restoration and remaking thereof.

A memory card is to be inserted into an electronic device so as to add a memory function. The memory card comprises a parent card and a child card, the child card including a semiconductor memory element and a lead as an external terminal of the memory element. The parent card includes a child card receiving portion and a child card insert port for inserting the child card into the child card receiving portion through the child card insert port, and a contact to be contacted with the lead of the child card within the child card receiving portion. A contact opening/closing slide is provided for causing a contacting portion of the contact to be shifted to a position in which it can contact with the lead while moving in the child card insert direction pushed by the child card. The parent card also includes a connector element for contacting with the electronic device.

摘要:
A brazing construction and method of brazing an abradable sealing material onto a base material is provided. The abradable sealing material is a tabular member having a cellular compartment construction in honeycomb form having empty compartments and partitions formed by overlapping a plurality of thin corrugated sheets. The abradable sealing material is brazed on the main material by, applying a stop-off agent on a side surface of the abradable sealing material except on a portion of the side surface close to a brazing face to form a stop-off area that prevents infiltration of a brazing filler metal in an overlapping part; superposing the brazing face of the abradable sealing material on the base material, such that the brazing filler metal is provided between the abradable sealing material and the base metal; and brazing the abradable sealing material to said base material.
