摘要： PURPOSE:To obtain a product of fiber-reinforced metal in which undermentioned fibers are unidirectionally oriented independently of the melting points of metals, by providing viscosity to a mixture of fiber reinforcement and metallic powder, extruding the above, and then subjecting the extruded matter to compacting and sintering. CONSTITUTION:A fiber reinforcement 1 of alumina, etc., is mixed with a metal powder 2 of Al alloy, etc., prepared by an atomizing method, etc. Then, water, glycerine, methylcellulose, etc., are added to the resulting mixture, which is kneaded so as to be provided with viscosity. This kneaded material is extruded so as to be formed into a green compact 3 consisting of the unidirectionally oriented fibers 1 and the above-mentioned powder 2, which is then formed into a sheet-like body. These sheet-like bodies are laminated into a laminated body 4, and, by applying hot pressing to the above, the plate-like product 6 mentioned above in which the fibers 1 are unidirectionally oriented can be obtained.

摘要： PURPOSE:To improve the wear resistance of a valve by projecting a laser beam to a part on the surface of a valve disk where a Co-base alloy is coated and forming a hardened layer of the Co-alloy only to the surface layer. CONSTITUTION:The Co-base alloy power is dissolved in a solvent and is uniformly coated on a seat surface 4 of the valve body 1 consisting of a 13Cr martensitic stainless steel. The laser beam is then projected to the coating by using a CO2 laser oscillator to melt and solidify the coating so that the Co-base alloy layer is formed only on the surface layer. As a result, the hardness is improved. The Co-base alloy has the highest wear resistance and erosion resistance among metallic materials and the material quality on the seat surface of the valve disk is improved by such properties.

摘要： PURPOSE:To attempt improvement of wear and abrasion resistance and erosion resistance by radiating laser beams on the surface of a valve in order to fuse, to cool rapidly and to congeal the surface. CONSTITUTION:On the surface of a valve 1 consisting of 13 chromemartensite stainless steel, laser beams are radiated using an O2 laser oscillator, and the seat surface part 4 of a valve board body 3, the circumferential part and the end part 5 of a trunk body 2 can be fused, cooled rapidly and congealed. By this, wear and abrasion resistance and erosion resistance of the valve surface can be improved.

摘要： PURPOSE:To make mass production of products having intricate shapes without the deterioration of reinforcing fibers and the formation of preforms by subjecting the molding obtd. by injection molding of a mixture composed of metallic material powder, reinforcing fibers and org. binders to degreasing then to calcination at the m.p. of the above-mentioned metallic material powder or below. CONSTITUTION:The metallic material powder, reinforcing fibers and org. binder are kneaded and the mixture composed thereof is injection-molded by using a desired metallic mold. The injection pressure and injection temp. in this stage are adequately set to adjust the flow rate and to prevent the generation of defects such as blowholes arising from the decomposition of the binder. The molding obtd. by such injection molding is degreased (to remove the org. binder by decomposing and evaporating the same). The calcination operation is executed at the m.p. of the metallic powder or below after the degreasing. The above- mentioned org. binder includes polymer binders such as PE and polystyrene having several ten thousands mol.wt. or below and paraffinic wax having several thousands mol.wt. or below which lender fluidity to the mixture composed of the metallic powder and reinforcing fibers.

摘要： PURPOSE:To prevent the leakage of a molten metal during pressurizing and to obtain a fiber reinforced metal having uniform structure by dividing a pressurizing ram in the axial line direction and disposing glass powder between the divided pressurizing lines. CONSTITUTION:A casting mold disposed therein with fibers 16 and metal 15 is heated to the liquid phase point of the metal 15 or above by a heating element 11 around said mold. The glass powder 17 disposed between the 1st step ram 14a and the 2nd step ram 14b is above the glass softening point. The softened glass 17 is deformed between the 1st step ram 14a and the 2nd step ram 14b and the clearance between an outside cylinder 12 and the glass 17 is eliminated when the pressure is exerted to the glass by a plunger via the 2nd step ram 14b. The clearance between the softened glass 17 layer and the cylinder 12 does not exist and therefore the molten metal 15 does not leak even if the pressure is exerted to the molten metal 15. The molten metal is penetrated into the gaps of the fibers 16 preformed to the prescribed voids, by which the fibers and the metal are combined.
摘要翻译：目的：为了防止在加压期间熔融金属的泄漏，并且通过在轴线方向上分压加压冲头并且在分隔的加压管线之间设置玻璃粉末来获得具有均匀结构的纤维增强金属。构成：其中设置有纤维16和金属15的铸模被围绕所述模具的加热元件11加热到金属15或更高的液相点。设置在第一台阶压头14a和第二踏板14b之间的玻璃粉末17高于玻璃软化点。软化的玻璃17在第一台阶压头14a和第二阶梯压头14b之间变形，并且当柱塞经由第二步骤压头14b施加到玻璃上时，消除了外筒12和玻璃17之间的间隙。软化玻璃17层和气缸12之间的间隙不存在，因此即使对熔融金属15施加压力，熔融金属15也不会泄漏。熔融金属被穿入预先形成的纤维16的间隙中纤维和金属组合在一起的规定的空隙。
