阳极保护 [yáng jí bǎo hù]
[化学] anodic protection
- 然而，防腐蚀铸层与钢脚间的结合不良将削弱锌的阳极保护作用。
However the poor bond between the anticorrosion casting coating and steel-foot would weaken the anodic protection of zinc. - 激光焊缝窄，基材锌层阳极保护作用得以保存，激光焊接板仍具有较好耐蚀性。
Since laser weld is narrow, and the anode protection effect of zinc on the base metal was not destroyed, the joint has good corrosion resistance. - 腐蚀介质到达基体时，将发生电偶腐蚀，铝涂层会作为牺牲阳极保护基体免受腐蚀。
Once corrosive solution arrived at the substrate, galvanic corrosion occurred, and aluminum coatings acted as the sacrificial anode protecting the steel substrate from corrosion.
