    摘要: The invention relates to the protection of metal boiler tubes from corrosion and erosion. Accordingly, the invention provides a metal boiler tube whereof at least a selected part of its surface is initially porous and whereof the initially porous surface has been coated with at least one stable metal oxide by the aplication to the porous surface of a solution containing salts or oxides of such metals followed by the conversion of such salts or treatment of such oxides of metals to attach the stable metal oxides to the porous surface.
