Menene Passivation

Passivation wani tsari ne na sinadarai wanda ke kawar da baƙin ƙarfe kyauta da sauran gurɓataccen ƙasa daga bakin karfe. Bayan tsaftacewa, ana bi da ƙarfe tare da ɗan ƙaramin oxidant, yawanci nitric acid ko citric acid, don haɓaka samuwar siraren sirara mai haske a saman.

Wannan Layer na kariya yana inganta juriyar ƙarfe ga tsatsa da lalata ta hanyar hana wuraren aiki waɗanda ke haifar da halayen sinadarai tare da muhalli.
