ANTICORROSIVE COATING STRUCTURE AND STEEL MEMBER
To provide an anticorrosive coating structure that has a metal substrate with an anticorrosive face, of which a part is coated with a corrosion-proof metal and another part is coated with a zinc-rich coating layer, wherein the corrosion-proof metal is protected from zinc embrittlement cracking even when the corrosion-proof metal is welded, and a steel member including the anticorrosive coating structure.SOLUTION: An anticorrosive coating structure 10 includes a corrosion-proof metal 16 that coats a part of an anticorrosive face 14 of a metal substrate 12, which requires corrosion protection, and a zinc-rich coating layer 18 that coats another part of the anticorrosive face 14. Between the corrosion-proof metal 16 and the zinc-rich coating layer 18 on the anticorrosive face 14, a separation region 14A is provided to separate them. A primer coating layer 20 is also provided to coat the separation region 14A.SELECTED DRAWING: Figure 1
【課題】金属基材の被防食面の一部が耐食性金属によって被覆され、他の一部がジンクリッチ塗膜層によって被覆されていて、前記耐食性金属に対して溶接を行う場合でも、該耐食性金属に亜鉛脆化割れが発生することが抑制された防食被覆構造および該防食被覆構造を備えた鋼部材を提供する。【解決手段】防食対象の金属基材１２の被防食面１４の一部を被覆する耐食性金属１６と、被防食面１４の他の一部を被覆するジンクリッチ塗膜層１８と、を備える防食被覆構造１０であって、被防食面１４において、耐食性金属１６とジンクリッチ塗膜層１８の間には、それらを隔てる分離領域１４Ａが設けられており、分離領域１４Ａを覆うように設けられたプライマー塗膜層２０を有してなる。【選択図】図１
