Abstract
Disclosed herein is a process for producing a narrow titanium-containing wire, comprising steps of: (i) providing a structure comprising a substrate having a titanium-containing surface and a porous layer containing narrow pores extending towards the surface; and (ii) forming narrow titanium-containing wires in the respective narrow pores by heat treatment of the structure obtained in the step (i).
Claims19
A process for producing a structure comprising steps of:
- (i) providing a substrate having a surface consisting essentially of at least one of titanium and a titanium alloy and a porous layer containing narrow pores extending toward the surface;
- and
- (ii) growing wires from a portion of the substrate in the respective pores by heat treatment of the structure obtained in step (i).
A process for producing a device having an electrode comprising the steps of:
- i) providing a member having a porous region obtained by anodic oxidation;
- and
- ii) growing wires from a portion of the substrate comprising titanium or a titanium alloy in respective pores of the porous region by a heat treatment under an atmosphere containing a hydrocarbon, wherein a layer with which voltage can be applied between the layer and said electrode is provided under the porous region of said member.
A process for producing a structure comprising the steps of:
- (i) preparing a substrate having a layer containing at least one pore, wherein the pore penetrates the layer;
- and
- (ii) forming a wire in the pore by a heat treatment of the structure obtained in step (i), wherein the wire is made of (a) a material from the substrate, which said material comprises titanium or a titanium alloy and (b) a material from a gas.
