Q355NH birta cimilada leh oo leh alxanka alxanka oo isku mid ah

Hordhac birta cimilada

Birta cimiladu waa heer bir ah oo leh iska caabin xawli ah oo heer sare ah, taas oo ah in lagu daro qadar yar oo Cr, Ni, Cu, P ah iyo walxo kale birta kaarboon si ay u sameeyaan lakab ilaalin dusha sare ee matrixka birta, si ay hoos ugu sii dhacdo daxalka.Iska caabinta daxalka atmospheric birta cimiladu waa 2 ~ 8 jeer in kaarboonka caadiga ah, oo leh caabbinta miridhku, kordhinta nolosha adeegga qaybaha qaab dhismeedka, khafiifinta iyo dhimista isticmaalka, iwm, inta badan loo isticmaalo baabuurta, buundooyinka, weelasha, dhismayaasha, munaaradaha. iyo soo-gaadhista kale ee muddada dheer ee dhismayaasha birta atmospheric.

Tusaha iska caabbinta daxalka atmospheric

Tusaha iska caabbinta daxalka atmospheric (I) waa index muhiim ah si loo qiimeeyo caabbinta cimilada ee alaabta, index ka weyn, si fiican u caabbinta daxalka atmospheric birta, waxaa guud ahaan la rumeysan yahay in marka index (I) ≥ 6.0 steel uu leeyahay jawi ka wanaagsan. iska caabin daxalka.

Tusaha iska caabinta daxalka atmospheric (I) waxaa loo xisaabiyaa sida soo socota:
I=26.01(%Cu)+3.88(%Ni)+1.20(%Cr)+1.49(%Si)+17.28(%P)-7.29(%Cu)(%Ni)-9.10(%Ni)(%P) -33.39 (%Cu)2
