Test : R\u00e9sistance \u00e0 la corrosion du tuyau duplex 2205 sous frottement dynamique de l'eau de mer<\/h2>\n

Le testeur de frottement et d'usure par frottement de l'eau de mer et la station de travail \u00e9lectrochimique ont \u00e9t\u00e9 utilis\u00e9s pour tester les changements dans le r\u00e9sistance \u00e0 la corrosion<\/a> de la tuyau en acier inoxydable duplex<\/a> lors de l'usure par glissement en eau de mer.<\/p>\n

\"Test<\/a><\/p>\n

Avant le test exp\u00e9rimental, l'\u00e9chantillon a \u00e9t\u00e9 immerg\u00e9 dans de l'eau de mer artificielle pendant 10 minutes. Une fois le potentiel de circuit ouvert statique de l'\u00e9chantillon stabilis\u00e9, le testeur de frottement et d'usure \u00e0 l'eau de mer a \u00e9t\u00e9 activ\u00e9. Le temps de glissement \u00e9tait de 60 minutes. Le testeur de frottement et d'usure a \u00e9t\u00e9 arr\u00eat\u00e9 et la surface de la surface apr\u00e8s usure par glissement a \u00e9t\u00e9 test\u00e9e Potentiellement.<\/p>\n

Le potentiel de circuit ouvert de la surface d'usure du tube en acier inoxydable 2205 en cas d'usure statique et glissante change : Le potentiel de circuit ouvert dans des conditions statiques d'eau de mer est d'environ -0,2 V, et avec l'augmentation du temps d'immersion, le potentiel de circuit ouvert est plus stable et a l\u00e9g\u00e8re tendance \u00e0 la hausse, indiquant qu'avec l'augmentation du temps de trempage, le film de passivation form\u00e9 \u00e0 la surface du tuyau en acier inoxydable 2205 est plus stable et plus dense, am\u00e9liorant ainsi la r\u00e9sistance \u00e0 la corrosion de l'acier duplex\u00a0;<\/p>\n

Lorsque l'usure par glissement commence, le potentiel en circuit ouvert diminue fortement jusqu'\u00e0 environ -0,75, et \u00e0 mesure que la charge appliqu\u00e9e augmente, le potentiel en circuit ouvert diminue davantage. Avec l'usure par glissement, le potentiel de circuit ouvert devient plus stable et inf\u00e9rieur \u00e0 -0,8V, donc 2205 Le potentiel de protection cathodique du tube en acier inoxydable a \u00e9t\u00e9 r\u00e9gl\u00e9 \u00e0 -0,8V. Les r\u00e9sultats du changement de potentiel de circuit ouvert ont montr\u00e9 que l'usure par glissement a endommag\u00e9 le film de passivation \u00e0 la surface du tube en acier inoxydable 2205, ce qui a entra\u00een\u00e9 une forte diminution du potentiel de circuit ouvert. Et r\u00e9parer \u00e0 un certain \u00e9quilibre dynamique, de sorte que le potentiel de circuit ouvert conserve une valeur stable pendant le processus de glissement\u00a0;<\/p>\n

Lorsque l'usure par glissement s'arr\u00eate, le potentiel en circuit ouvert augmente rapidement, et avec l'augmentation du temps de trempage statique, le potentiel en circuit ouvert redevient stable, environ -0,55 ou inf\u00e9rieur \u00e0 -0,2 avant l'usure par glissement.<\/p>\n

Ce qui pr\u00e9c\u00e8de montre que l'usure par glissement du 2205 tuyau duplex<\/a> modifie la microstructure de la surface et r\u00e9duit le potentiel de circuit ouvert de la surface d'usure.<\/p>","protected":false},"featured_media":5613,"template":"","categories":[186],"tags":[],"class_list":["post-5612","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nCorrosion Resistance Of 2205 Duplex Pipe Under Dynamic Seawater Friction -
