摘要： A joined body 20 includes a porous ceramic 22 made of porous ceramic, a metal member 24 made of a metal, and a joint 30 formed of an oxide ceramic that penetrates into pores 23 of the porous ceramic 22 and joins the porous ceramic 22 to the metal member 24. The penetration depth of the oxide ceramic into the pores of the porous ceramic is preferably 10 μm or more, and more preferably 15 to 50 μm. The joined body 20 may be produced through a joining step of forming a joint by placing a metal raw material between a porous ceramic and a metal member and firing the metal raw material in the air at a temperature in the range of 400° C. to 900° C., where an oxide ceramic produced by oxidation of the metal raw material penetrates into the pores of the porous ceramic in the joint.

摘要： The invention relates to a method of forming a coating or of three-dimensional structural elements on substrate surfaces which is/are formed by TiAl. Said coating/Said three-dimensional structural elements is/are manufactured by laser build-up welding. The procedure is followed in the method in accordance with the invention that titanium and aluminum are supplied into the region of influence of at least one laser beam in wire and/or band form in a pure or alloyed form in each case as a single wire or a single band. They are melted by the thermal input and in this respect the materials are mixed with one another. The coating or three-dimensional structural elements are thereby formed with TiAl on the substrate surface.

摘要： A wear-resistant member production method includes: forming a clad layer by moving, relative to a substrate while feeding cladding powder onto the substrate and melting it using a local heating device; and cutting the clad layer. The cladding powder includes matrix powder containing a copper-based alloy, and hard powder including, as a hard phase, a silicide containing one or more elements selected from Cr, Fe, Co, Ni, and Cu, and one or more elements selected from Mo, W, and Nb. The hard powder includes first hard powder and second hard powder. The second hard powder is fed, separately from the first hard powder, to a melt pool formed by melting the first hard powder and the matrix powder, such that at least part of the second hard powder remains unmelted within the clad layer.
