saxan bir ahdhab ahaantii waa nooc ka mid ah alaabada aan sahlanayn in la soo saaro daxalka, marka laga reebo xaalado halis ah. Dhab ahaantii, waa wax aan suurtagal ahayn in alaab kasta oo aan la daxdin karin, haddii saxankeena birta ah uu daxaloobay, waxay saameyn kartaa isticmaalkeeda caadiga ah, markaa waxaan u baahanahay inaan sameyno tallaabooyin ka hortag ah si looga fogaado xaaladdan. Halkan waxaa ah laba arrimood oo sababi kara daxalka taarikada birta ah.
1. Daxalka Electrochemical.
saxan bir ahama ay sabab u tahay xoqin ay sababto xiriir la qaybaha birta carbon, saxan birta ah ka dib formation of unugyada galvanic leh dhexdhexaad ah daxalka, kaas oo soo saari doona daxalka electrochemical, pickling saamayn passivation ma wanaagsana, waxa kale oo ay ka dhigi doonaa filimka passivation on dusha saxan ma aha mid lebis ah ama aad u dhuuban, sidaas darteed waa ay fududahay in la soo saaro daxalka electrochemical, splash iyo qaybaha kale ee saxan fudud ka dib markii unugyo galvanic saxan ka dib Natiijadu tahay daxalka korantada, nadiifinta passivation pickling ma aha mid nadiif ah, taasoo keentay pickling haraaga passivation dareere ah alaabta daxalka kiimikada saxanka, ka dibna la sameeyo daxalka electrochemical saxanka.
2. Kiimikada daxalka.
Xaaladaha qaarkood, saliid badan, boodh ama acid, cusbo ku lifaaqan dusha saxan bir ah oo dhexdhexaad ah, falcelinta kiimikada leh qaybo ka mid ah saxanka, taasoo keentay daxalka kiimikada iyo miridhku, nadiifinta passivation ma nadiif ah oo ku filan 3 ay sababtay dareeraha haraaga ah ee haray, taas oo si toos ah u daxalisay saxan, dusha saxan la xoqay, taasoo keentay in filimka passivation burburay, Sidaa darteed, saxan la dhimay awoodda kiimikaad ee dhexdhexaadka ah, kaas oo si fudud u hagaajin karo kiimikada, miridhku
