<p>Disclosed is an optical fiber-housing metal pipe, comprising a base body of an optical fiber-housing metal pipe, an aluminum layer formed on the surface of the base body, and an oxide layer formed on the aluminum layer, the oxide layer serving to improve the corrosion resistance and wear resistance of the optical fiber-housing metal pipe. Also disclosed is an optical fiber-housing metal pipe comprising a base body of an optical fiber-housing metal pipe, an Al-X alloy layer formed on the surface of the base body, where X is one or two kinds of elements selected from the group consisting of Mn, Ti, Ni, Cr, Nb, Mg, Fe, In and Sn, or an Al-based composite layer containing at least one kind of a material selected from the group consisting of a carbide, an oxide and an organic compound. Further, the present invention provides a method of manufacturing an optical fiber-housing metal pipe excellent in corrosion resistance, comprising the step of forming an aluminum or aluminum alloy layer on the surface of a base body of an optical fiber-housing metal pipe, and the step of smoothing the aluminum or aluminum alloy layer to set a maximum height (Ry) of the aluminum or aluminum alloy layer at 3 mu m or less. <IMAGE></p> |
