Althes an aghaidh chrome ath-sheasamh
Tha a mhion-a-machrinn iar-chrome aluminum (fecral) mar as trice a thathas a 'cleachdadh stuthan leotha fhèin ann an tagraidhean leis an teòthachd obrachaidh as motha suas gu 1,400 ° C (2,550 ° F).
Tha fios gu bheil comas luchdaichte uachdar nas àirde aig na Mion-allaidh Ferritaic, Neach-gèilleadh nas àirde agus dùmhlachd nas ìsle na roghainnean magadh (Nor) a dh 'fhaodas eadar-theangachadh gu stuthan nas lugha de stuthan agus sàbhalaidhean cuideam. Faodaidh na teòthachdan obrachaidh as àirde a bhith a 'leantainn gu beatha nas fhaide. Bidh Alathan Aluminum Iar-Life Chroome Huuminum liath liath liath liath liath liath liath (al2o3) aig 1,000 ° C (1,832 ° F) a tha a 'cur an aghaidh neo-àbhaisteach ann an inslator dealain. Thathas a 'meas gu bheil cruthachadh oxide fèin-inntinn agus a' dìon an aghaidh cuairt ghoirid ma thachras meatailt ri fèill meatailt. Tha neart meacanaigeach crolaidh chrome iar-alùmanum ann an allaidh iarainn agus an taca ri stuthan nicil chrome a bharrachd air neart creep nas ìsle.
