Bir kulul
Birta u adkeysiga kuleylka ayaa waxaa loola jeedaa birta qaaska ah ee loo yaqaan 'pental' oo gaar ah oo leh heerkulka sare ee kiimikada ah, oo uu sifiican ugula qabsan karo xaaladaha kuleylka sare {{1} inta badan loo isticmaalo soo-saarista kuleylka, mashiinka batroolka, iyo qalabka kale ee heerkulka ah ee ka shaqeeya qaybo ka shaqeeya {{2} {}
(1) Fikradda caabbinta kuleylka
Caabbinta kuleylka ee birta waxaa ku jira labadaba xasilloonida heerkulka ah iyo xoogga heerkulka sare .
Deganaanshaha heerkulka ah waxaa loola jeedaa awoodda birta si ay uga hortagto burburka kiimikada ee warbaahinta kala duwan, kuwa ugu muhiimsanna ay ku dadaalaan anti-{{0} ee ku darista anti-{{1} ee ku daraya anti-{{0} ee ku saabsan awoodda birta, sababta oo ah cr, al iyo s cr ayaa dhisi kara isqabasho iyo ilaalin cr oksijiin marka loo eego heerkulka sare2O3,A12O3laga yaabee Sio2Filim . CR waa sheyga loo yaqaan 'aler-ka la doorbido . markii birta WR5%, heerkulka antioxidant ee birta ayaa gaari kara 900 shahaado; Marka WCR 20% ~ 25%, heerkulka antioxidant ee birta ee birta ah ({9}, iwm {{9} ee {}, iwm {{9} ee {}, iwm {{9} ee {}, iwm {{9}, iwm {{9} ee {}} tani waxay sidoo kale horumarin kartaa xoogga ka hortagga anti-ka ee filimka oxida ah iyo birta surface. In the surface of steel seepage aluminum, silicon or chromium aluminum, chromium and silicon co-seepage have significant antioxidant capacity.
Awoodda heerkulka sare waxaa loola jeedaa awoodda birta si looga hortago cilladaha balaastigga ah ee heerkulka badan {}} ah oo lagu daray si loo qiimeeyo . inta badan lagu daro si loo qiimeeyo . ah oo lagu daro si loo qiimeeyo . ah oo lagu daro si loo qiimeeyo . ah oo lagu daro si loo qiimeeyo . ah oo lagu daray cr, {0} in lagu daro sicirka . inta badan lagu daro sicirka . si caadi ah oo lagu daray cr, {0} in lagu daro si loo qiimeeyo . inta badan lagu daro sicirka {{0}, w0, kor u qaadida heerkulka dib-u-dhaca, kordhinta heerkulka dib-u-soo-celinta iyo kordhinta xasilloonida xisaabta; Ku darista v, TI, NB, al iyo walxaha kale, sameynta karbaashka leh xasilloonida sare iyo xasilloonida kuleylka wanaagsan, ka hortagga horumarka gurguurta iyo kala firidhsan; Raadinta B oo dhifsan (Re) walxaha (RE)) iyo xoojinta xoogga heerkulka sare ee birta .
