摘要： PURPOSE:To prevent a defect generated at welding time and to improve the performance of a product by monocrystalizing a blade, subjecting to a heat treatment after welding by dividing it and welding it by setting such welding conditions as causing no welding defect after welding in manufacturing the welding structural blade consisting of a Ni base alloy. CONSTITUTION:The core supporting hole 2 provided at the tip part of a blade is joined by sealing it in order to facilitate support and melt-through of the core of the blade of complicated cooling structure consisting of a Ni base alloy. Or after welding said blade tip part by dividing it in the state of like horizontally splitting it the cap of the blade tip is integrated by welding it to the blade. The material is of a monocrystal or similar to that and a filler rod of Fe or Ni is used and welded under inert atmosphere or vacuum to prevent the welding crack caused by a grain boundary. The split welding is thus enabled in case of welding the blade having a complicated cooling hole, the defect generated at welding time is prevented and the product performance can be improved.

摘要： PURPOSE:To enable the mass production of the cooler with the high-density arrangement of fine coolant paths which has a large area of heat transfer and high cooling efficiency, by a method wherein photoetching is adopted for the formation of cooling grooves serving as junction coolant paths. CONSTITUTION:A copper plate of 0.5mm thickness and a plate of 0.5mm thickness comprised of 10 pieces of cooling-groove patterns 0.1mm wide and 0.1mm deep formed by photoetching are prepared and loaded into a vacuum chamber. After the junction plane is cleaned by irradiation with Ar ion beams, a Cu-30wt%Ti alloy film is deposited 2mum by sputter evaporation. These films are laminated, loaded into a diffusion furnace, and subjected to 1hr junction under a junction pressure of 0.2kg/mm at 940 deg.C into an integral body. Then, coolers are produced by cutting each cooling-groove pattern; finally, pipes serving as coolant inflow-outflow ports are brazed, thus completing the coolers.

The constituting material 3 of such target 1 is driven out by the electrons confined in the magnetic field 2 of magnets N, S and is stuck onto the joint surfaces of the materials 5 by which a sputtered alloy film 4 is formed. The films 4, 4 are brought into tight contact with each other and the materials 5, 5 are pressurized and are heated and held to and at a prescribed temp. by which the materials are diffusion-joined. The sputtered alloy film for diffusion joining is uniformly formed with good dimensional accuracy and the joint part having high quality is obtd. in short time by the above-mentioned method.
