摘要： PROBLEM TO BE SOLVED: To provide a graphite tray which hardly causes the breaking phenomenon of a thermally sprayed coating film or the stripping phenomenon of the thermally sprayed coating film from a tray base material caused by hardly densifying the thermally sprayed coating film formed on the sintering graphite tray base material for sintering a product of a sintered hard alloy, a cermet or metal and hardly causes the melt sticking between the product and the thermally sprayed coating film. SOLUTION: The graphite tray is provided with a plurality of thermally sprayed coating films formed by being laminated on the graphite tray of the base material and a 1st layer of the thermally sprayed coating film being in contact with the base material is composed of a thermally sprayed coating film consisting essentially of erbia-containing zirconia or gadolinia-containing zirconia and the uppermost layer of the thermally sprayed coating film being in contact with the product is composed of a yttria-zirconia composite consisting essentially of yttria or a yttria-yttribium composite consisting essentially of yttria.

摘要： PROBLEM TO BE SOLVED: To provide a graphite tray used for sintering a product of cemented carbides or cermets, each having a thermally sprayed coating of an oxide on its surface, which is almost free from oxidation phenomenon at the interface between the coating and its surface even when the coating is prevented from becoming oxygen defect type and which thereby improves the durability of the coating. SOLUTION: A thermally sprayed coating of an oxide containing ≥80 wt.% Yb 2 O 3 or a thermally sprayed coating of a Yb 2 O 3 -Y 2 O 3 multiple oxide containing ≥50 wt.% Yb 2 O 3 is formed on a surface on which the product of the cemented carbides or the cermets is mounted and held.

摘要： PROBLEM TO BE SOLVED: To provide a vessel made of carbon which prevents deteriolation in product quality caused by carburizing or its conversion into carbide, and prevents thermally sprayed coatings from being cracked/peeld off with the lapse of years. SOLUTION: Disclosed is the vessel (1) made of carbon wherein thermally sprayed coatings (2, 3, 4) are formed on the surface where the material to be sintered, a brazed component or a diffusion-bonded component is placed. As the thermally sprayed coatings, an undercoat (2) composed of a niobium metal, a tantalum metal, a niobium alloy including an Nb-W-based alloy or a tantalum alloy and a topcoat composed of oxide ceramics (3, 4) of Al 2 O 3 , MgO-Al 2 O 3 , Y 2 O 3 , ZrO 2 , Gd 2 O 3 , Yb 2 O 3 or ZrO 2 -Y 2 O 3 series are formed in order.

摘要： PURPOSE:To lengthen the length of a tube stock possible to be formed by mounting one of outside and inside tube bodies on a moving frame body and the other on a fixed frame and constituting a bellows forming pressure means and a tube stock sending means of a moving hydraulic cylinder possible to move the moving frame body in the lengthwise direction. CONSTITUTION:Fixed side split dies 10, 10' with on-off hydraulic cylinders 8, 8' are mounted on the fixed frame 31. Moving side split dies 11, 11' are mounted on the moving frame body 28. A forming pressure hydraulic means 6 and an annular seal hydraulic means 15, 16 are composed of the outside tube body 19, the inside tube body 20 and a central tube body 22. One of the outside and inside tube bodies 19, 20 is mounted on the moving frame body 28 and the other is on the fixed frame 31. The bellows forming pressure means and the tube stock sending means are made of the moving hydraulic cylinder 26 possible to move in the lengthwise direction. In this way, the moving hydraulic cylinder can play two parts of pressing the side of the bulging part of the tube stock and sending out the tube stock.
