摘要： A sliding component and its producing method are provided. The sliding component includes a base section made of steel or cast iron, and a sliding section having a sliding surface, made of copper alloy including hard particles, and joined to the base section. The hard particles in the sliding section are arranged such that those in a region including an outer periphery of the interface with the base section have their longitudinal directions coinciding with the directions along the outer periphery as compared to those in an inner peripheral side. This improves the durability of the sliding section in its region including the outer periphery of the interface with the base section.

摘要： The present invention relates to a tube for transporting fluids in seawater. The tube has a tubular body formed of an alloy selected from duplex stainless steel, superduplex stainless steel, a ferritic steel, a martensitic steel or a nickel superalloy and a layer configured to protect the tube from hydrogen induced stress cracking arranged on an outer surface of the tubular body. The layer is formed of an alloy having a copper content of 50-95 wt % and a nickel content of 5-50 wt %. The tube has a metallurgical bond, formed in the solid state, at an interface between the tubular body and the layer. The metallurgical bond is formed by a hot isostatic pressing process for a predetermined time at a predetermined pressure and a predetermined temperature. The present invention also relates to a method for manufacturing a tube. The present invention also relates to a subsea arrangement.

摘要： A welding structure includes: a first metal member and a second metal member that are superimposed and welded together. The first metal member has a hole. The second metal member includes a nugget portion where a part of the second metal member has been melted by heat of laser light and has re-solidified. A peripheral portion of the hole in the first metal member covers the nugget portion. A part of the nugget portion is exposed through the hole.

摘要： A machine component includes a first region having a first linear expansion coefficient, and a second region having a second linear expansion coefficient greater than the first linear expansion coefficient and joined to the first region. A region including an outer periphery of an interface between the first region and the second region is inclined toward the second region side over the entire periphery. On a surface of the first region, a groove is formed to extend along the outer periphery of the interface.

摘要： A method of assembling a first part made from a metal and a second part includes providing a first part comprising an assembly surface, and a second part comprising at least one through orifice. At least part of the second part is arranged on the assembly surface such that the orifice extends across from the assembly surface. A metal connecting part is positioned on the orifice to cover the orifice across from the assembly surface. The connecting part and/or the assembly surface are projected on one another to obtain high-speed plating and welding between the connecting part and the surface part.
