A slide member is provided with a base material, a plated slide layer and an intermediate plated layer. The plated slide layer contains a solid lubricant. The intermediate plated layer is disposed between the base material and the plated slide layer, the intermediate plated layer increasing cohesion of the base material and the plated slide layer. The plated slide layer has a content of the solid lubricant in a range from 30 to 70 vol %, inclusive.

Provided are a zinc-base plated steel material comprising a base steel and a zinc-based plated layer and a post-treatment film, which are sequentially formed on the base steel. The post-treatment film comprises an oxide or oxide salt of at least one group A element selected from B, Al, V, and Fe and an organic compound, wherein the content of oxygen atoms in the post-treatment film is 50 atom % or more, and wherein when the mole number of oxygen atoms forming a covalent bond with hydrogen in the post-treatment film is a and the mole number of oxygen atoms not forming the covalent bond with hydrogen is b, a/b is 0.3 or greater; and a composition for forming the post-treatment film.

A workpiece of Ti or a Ti alloy includes a surface with a coating layer of titanium nitride. A region of the surface includes a connection zone of a Ti—N solid solution alloy. A second Ti or Ti alloy workpiece is contacted with the connection zone, and a weld joint is formed across the connection zone with a resistance welding process. The weld joint extends into the first Ti workpiece and the second Ti workpiece.

Provided is a titanium composite material 1 including: a first surface layer portion 2; an inner layer portion 4; and a second surface layer portion 3; wherein: the first surface layer portion 2 and the second surface layer portion 3 are composed of a titanium alloy; the inner layer portion 4 is composed of a commercially pure titanium including pores; a thickness of at least one of the first surface layer portion 2 and the second surface layer portion 3 is 2 μm or more, and a proportion of the thickness with respect to an overall thickness of the titanium composite material 1 is 40% or less; and a porosity in a cross section perpendicular to a sheet thickness direction is more than 0% and 30% or less.

Compositions are provided that exhibit an austenitic nickel microstructure. The compositions comprise Ni, Cr, Mo and at least one element selected from the group consisting of Al, Si, and Ti. Feedstock having the composition may be in the form of a cored wire or wires, a solid wire or wires, or a powder.

In various embodiments, electronic devices such as touch-panel displays incorporate interconnects featuring a conductor layer and, disposed above the conductor layer, a capping layer comprising an alloy of Cu and one or more refractory metal elements selected from the group consisting of Ta, Nb, Mo, W, Zr, Hf, Re, Os, Ru, Rh, Ti, V, Cr, and Ni.

To provide a copper-clad laminate which maintains adhesion between a resin film and a conductor layer and which suppresses the occurrence of wrinkles. A copper-clad laminate has a base film containing a thermoplastic resin, an underlying metal layer film-formed on a surface of the base film by a dry plating method, and a copper layer film-formed on a surface of the underlying metal layer. The underlying metal layer has a mean thickness of 0.3 to 1.9 nm. Since the underlying metal layer has a mean thickness of 0.3 nm or more, it is possible to maintain adhesion between the base film and a conductor layer. Since the underlying metal layer has a mean thickness of 1.9 nm or less, it is possible to suppress an increase in the temperature of a film during film-forming of the underlying metal layer, and it is possible to suppress the occurrence of wrinkles.

An optical mount part having a body that includes a composite of a titanium-zirconium-niobium alloy. The titanium-niobium-zirconium alloy includes titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 weight % (wt. %) niobium. The titanium-niobium-zirconium alloy has a congruent melting temperature of about 1750 to about 1800 Celsius ( C.).

In various embodiments, electronic devices such as touch-panel displays incorporate interconnects featuring a conductor layer and, disposed above the conductor layer, a capping layer comprising an alloy of Cu and one or more refractory metal elements selected from the group consisting of Ta, Nb, Mo, W, Zr, Hf, Re, Os, Ru, Rh, Ti, V, Cr, and Ni.

A titanium material for hot rolling 1 includes a titanium cast piece 3, and titanium sheets 4 that are welded to faces corresponding to rolling surfaces 3a of the titanium cast piece 3. The titanium cast piece 3 and the titanium sheets 4 have the same kind of chemical composition. The titanium material for hot rolling 1 can maintain good surface properties after hot rolling even if a slabbing process or a finishing process is omitted.
