摘要： PURPOSE:To facilitate brazing for corrugated fins of heat exchanger, by intermediately providing spacers between each of bends of meandering pipe adjacent to each other, when the tops of fins and the surface of pipe are brazed after the corrugated fins of slant type are inserted to be pinched with pressure between each of the straight parts of meandering pipe. CONSTITUTION:The heat exchanger is installed in a jig, with corrugated fins 2 of slant type inserted between each of straight parts 21 of the meandering pipe 3, and spacers 20 having rigidity as equal as of bends 23 intermediately provided to the open parts. Then the heat exchanger is pinched with pressure between the upper and the lower supporting boards 9 and 8 of the jig. As a result, the corrugated fins 2 are also pinched with pressure by the straight parts 21 of the pipe. Since the amount of displacement of bends 23 and that of open parts are being made equal by the spacers 20 intermediately provided between each of them, the straight parts 21 of the pipe are pressed in parallel to each other and can pinch the corrugated fins uniformly. The tops of corrugated fins 2 and the surface of straight parts 21 of the pipe are closely contacted to each other, therefore, brazing can be performed in this condition.

摘要： PURPOSE:To easily produce a cylinder of superior abrasion resistance and sliding characteristics by using a core which is coated with a soluble material and a liner material for cylinder on the surface of a cylindrical core material, in casting a cylinder for engines. CONSTITUTION:A lightweight cylinder used for automotive engines, compressors for coolers, etc. is die-cast of an Al alloy. Since the Al alloy is inferior in abrasion resistance, lubricity, etc., a liner which is superior in these characteristics is formed on the inside surface of the cylinder. A water soluble material 2 such as NaCl which firmly solidifies when melt-sprayed and is readily made dissolved with water or the like is melt-sprayed onto the surface of a cylindrical core material 1 of 0.2- 4mm. thickness for use as the core. A cylinder liner material 3 such as metals, ceramics or cermet is melt-sprayed thereon to 0.5-1.5mm. thickness and this is fitted onto a mandrel 5 of a die-casting machine. Molten Al alloy is cast to insert the liner material 3 to the inside surface of the cylinder 4, and the core material 2 is removed easily by dissolving NaCl in water.

摘要： PURPOSE: To improve considerably corrosion resistance by subjecting Al or the alloy thereof to a Zn diffusion-cementation treatment then anodizing the surface thereof.
CONSTITUTION: Al or an Al alloy is subjected to a Zn diffusion-cementation treatment. The surface thereof is anodized to elute a part of Zn and to form an oxide film consisting essentially of Al, thereby controlling the concn. of the diffused Zn and improving considerably the corrosion resistance. After an oxide film consisting essentially of Al is formed, the alloy is dipped in boiling water or exposed in steam to form the hydrate of Zn and Al or the alloy is dipped thereafter in a chemical conversion liquid contg. dichromate or chromate to change the Zn in the oxide film to insoluble zinc chromate, by which more preferable result is obtd.

摘要： PURPOSE:To drastically increase the number of time capable of repeatedly using a core material, in a method for forming a transfer flame spraying film on the surface of the core material having coefficient of expansion higher than that of said transfer flame spraying film, by prelimiarily forming an anodic oxidation film on the surface of the core material. CONSTITUTION:For example, in preparing the cylinder of a compressor for an engine, an anodic oxidation film 1' is applied to the plasma spraying surface of a core material 1 made of an Al base alloy. In the next step, a desired flame spraying material is uniformly flame sprayed to the core material 1a in a desired thickness. At this time, blast treatment applied as the pretreatment of usual flame spraying is not applied to the core material 1a and only degreasing is applied thereto while the core material 1a is preheated prior to flame sparying to sufficiently expand the same under heating. When the core material is cooled to a room temp. after flame spraying, a gap is formed between the flame spraying film 10 and the core material 1a because of the difference in coefficient of expansion therebetween and, because the core material 1a is smooth, the film 100 can be easily separated. The mantle 12 of an Al die cast mold 11 is covered with this film 100 and the outer periphery of said film is subjected to internal chill transfer by an Al base alloy 13.
摘要翻译：目的：为了大幅度地增加能够重复使用芯材的时间，在将具有比所述转印火焰喷涂膜高的膨胀系数的芯材的表面上形成转印火焰喷涂膜的方法中，在芯材表面形成阳极氧化膜。构成：例如，在制造发动机的压缩机的气缸时，将阳极氧化膜1'施加到由Al基合金制成的芯材1的等离子体喷涂面上。在下一步骤中，将期望的火焰喷涂材料以期望的厚度均匀地火焰喷涂到芯材1a上。此时，作为通常的火焰喷涂的预处理而施加的喷砂处理不施加到芯材1a上，并且只有在芯材1a在加热之前在火焰喷射之前被预热而充分膨胀时才将其脱脂。当芯材冷却到室温时在火焰喷涂之后，由于它们之间的膨胀系数的差异，在火焰喷涂膜10和芯材1a之间形成间隙，并且由于芯材1a平滑，所以膜100容易分离。铝压铸模具11的外壳12被该膜100覆盖，并且所述膜的外周由Al基合金13进行内部冷却转印。

摘要： PURPOSE:To enhance the corrosion resistance of the heat exchanger by a structure wherein a heat exchange tube consists of a cladding material of pure aluminum and a core material of aluminum alloy. CONSTITUTION:The heat exchanger is made of an aluminum clad tube, which consists of the cladding material 4 of pure aluminum and the core material 3 of aluminum alloy, which is nobler than pure aluminum with respect to electrode potential and along the periphery of which fins 2 are fixed by vacuum soldering. Owing to the structure as described above, because pure aluminum is used as the cladding material of the aluminum clad tube, the contamination by zinc in a vacuum soldering furnace, which is the conventional problem in vacuum soldering, can be completely evaded and, because the core material 3, which is nobler than pure aluminum with respect to electrode potential, the cladding material 4 turns to be a sacrificial anode. Accordingly, the heat exchange tube 1, made of aluminum clad tube of subject heat exchanger has more excellent pitting corrosion resistance than that made of aluminum tube having no clad structure.
