摘要： PURPOSE:To aim at enhancing the hydrogen-corrosion countermeasure by subjecting a welded metal part and thermally affected part of a welded structure member to shot-peeling treatment after it is welded and post-weld heat- treatment. CONSTITUTION:After a welded structure for a high temperature and high pressure hydrogen gas pressure container or the like, is welded and subjected to post-weld heat treatment, it is subjected to shot-peeling treatment. With this process, it is possible to prevent micro-strain which is liable to generate at the interface between carbide and the base, and therefore it is possible to prevent methanization due to the diffusion and collection of hydrogen to the above- mentioned parts, which are problems during residual tensile stress action, thereby it is possible to aim at enhancing the hydrogen corrosion resistance.

摘要： PURPOSE:To prevent the stripping and cracking of a cladding member by forming a ferrite decarburized layer at a required depth on the surface of a steel base material and cladding by welding an austenitic stainless steel on said surface. CONSTITUTION:There are various methods to be adopted for decarburizing the surface of the steel base material in addition to a method using CO2. If the depth of the ferrite decarburized layer is =1.5mm.. The austenitic stainless steel welding material is not particularly limited. The operation is more convenient if the welding material consisting essentially of 19-26W% Cr, 9-23W% Ni and the balance Fe and added with Si, Mn and Nb for the purpose of improving weldability is used.
摘要翻译：目的：通过在所述表面上焊接奥氏体不锈钢，在钢基材和包层的表面上形成所需深度的铁素体脱碳层来防止包层部件的剥离和破裂。构成：除了使用二氧化碳的方法之外，还有各种各样的方法用于对钢基材表面进行脱碳。如果铁素体脱碳层的深度<1.5mm，铁素体脱碳层通过焊接在奥氏体不锈钢的包层阶段熔化，从而降低防止剥离和开裂的效果。因此，铁素体脱碳层的深度被限制为> = 1.5mm。奥氏体不锈钢焊接材料没有特别限制。使用基本上由19-26W％Cr，9-23W％Ni和余量的Fe组成的焊接材料，为了提高可焊性而加入Si，Mn和Nb的操作更方便。

摘要： PURPOSE: To improve the durability of the air nozzle by a method wherein the main body of the over-fire air nozzle is subjected to a diffusion-penetration treatment with Al or the like and then flame-sprayed with Ni-Cr alloy and finally flame-sprayed with ceramic material thereon.
CONSTITUTION: The desired part in a metallic material 3 is permeated by diffusion with metal such as Cr, Al, Al-Cr alloy, Si, B or the like by means of diffusing permeation treatment method in order to form diffusing permeation treated layers 4. At this time, only the diffused layers are left behind by removing pure metallic layers at the outmost surface by means of blasting. In succession, Ni-Cr alloy layers 5 are formed on said diffused layers by means of plasma spraying method. The sprayed layers 5 serve for the improvement of the adhesiveness of ceramic material in the next process and for obtaining better adhesiveness by promoting the alloying with substrate diffusing permeation treated layers 4. Furthermore, the sprayed layers 5 are coated with ceramics 6 such as zirconia, which has excellent oxidizing resistance, thermal resistance and the like, or the like in order to give the layers 5 oxidizing resistance, thermal resistance and corrosion resistance. And, the air nozzle is divided into two pieces or into a main body side nozzle 7 and a tip side nozzle 8, both of which are fitted with each other by bolts 9, resulting in enabling to change the burnt-out piece.

摘要： PURPOSE:To cheaply obtain a damping material with high damping capacity in large quantities by sensitizing the surface of steel after heat treatment followed by crystal boundary etching and coating of a resin film. CONSTITUTION:An austenitic stainless steel strip from uncoiler 1 is passed through a pretreating process consisting of degreasing vessel 2, washing vessel 3 and dryer 4, and it reaches heat treating furnace 6, where the strip surface is sensitized by high frequency heating or the like. The strip is then cooled with cold air cooler 7 in an inert gas atmosphere and subjected to crystal boundary etching in a boiling aq. soln. contg. copper sulfate and sulfuric acid for several min to form fine cavities. Resin film 14 is press. bonded to the strip with roll 3, and the strip reaches coiler 18 through hardening furnace 15, cooler 16, etc. Owing to innumerable fine cavities vibration is prevented, and the resin film prevents sound waves from escaping out. Thus, a damping material with high damping capacity is cheaply obtd. in large quantities.
