<\/a><\/p>\nAntes do teste experimental, a amostra foi imersa em \u00e1gua do mar artificial por 10 minutos. Depois que o potencial de circuito aberto est\u00e1tico da amostra foi estabilizado, o testador de desgaste e fric\u00e7\u00e3o de limpeza de \u00e1gua do mar foi ligado. O tempo de deslizamento foi de 60 minutos. O testador de atrito e desgaste foi interrompido e a superf\u00edcie da superf\u00edcie ap\u00f3s o desgaste por deslizamento foi testada. Potencial.<\/p>\n
O potencial de circuito aberto da superf\u00edcie de desgaste do tubo de a\u00e7o inoxid\u00e1vel 2205 em mudan\u00e7as de desgaste est\u00e1tico e deslizante: O potencial de circuito aberto sob condi\u00e7\u00f5es est\u00e1ticas da \u00e1gua do mar \u00e9 de cerca de -0,2 V, e com o aumento do tempo de imers\u00e3o, o potencial de circuito aberto \u00e9 mais est\u00e1vel e tem um tend\u00eancia de ligeiro aumento, indicando que Com o aumento do tempo de imers\u00e3o, o filme de passiva\u00e7\u00e3o formado na superf\u00edcie do tubo de a\u00e7o inoxid\u00e1vel 2205 \u00e9 mais est\u00e1vel e mais denso, melhorando assim a resist\u00eancia \u00e0 corros\u00e3o do a\u00e7o duplex;<\/p>\n
Quando o desgaste por deslizamento come\u00e7a, o potencial de circuito aberto diminui drasticamente para cerca de -0,75 e, \u00e0 medida que a carga aplicada aumenta, o potencial de circuito aberto diminui mais. Com o desgaste por deslizamento, o potencial de circuito aberto se torna mais est\u00e1vel e inferior a -0,8 V, ent\u00e3o 2205 O potencial de prote\u00e7\u00e3o cat\u00f3dica do tubo de a\u00e7o inoxid\u00e1vel foi definido para -0,8 V. Os resultados da mudan\u00e7a de potencial de circuito aberto mostraram que o desgaste por deslizamento danificou o filme de passiva\u00e7\u00e3o na superf\u00edcie do tubo de a\u00e7o inoxid\u00e1vel 2205, o que fez com que o potencial de circuito aberto diminu\u00edsse drasticamente. E repare a um certo equil\u00edbrio din\u00e2mico, de forma que o potencial de circuito aberto mantenha um valor est\u00e1vel durante o processo de deslizamento;<\/p>\n
Quando o desgaste por deslizamento para, o potencial de circuito aberto aumenta rapidamente e, com o aumento do tempo de imers\u00e3o est\u00e1tica, o potencial de circuito aberto volta a ficar est\u00e1vel, cerca de -0,55 ou menos de -0,2 antes do desgaste por deslizamento.<\/p>\n
O acima mostra que o desgaste por deslizamento do 2205 tubo duplex<\/a> muda a microestrutura da superf\u00edcie e reduz o potencial de circuito aberto da superf\u00edcie de desgaste.<\/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 -
