NiCr 80/20ucingo lokutshiza olushushuyimathiriyeli ekumgangatho ophezulu eyenzelwe izicelo zokutshiza i-arc. Olu cingo lwenziwe nge-80% yenickel kunye ne-20% yechromium, iyenza ibe lolona khetho lubalaseleyo ekudaleni iingubo ezifuna ukumelana nobushushu obuphezulu, ukumelana nokugqwala, kunye nokumelana ne-oxidation. I-NiCr 80/20 isetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya i-aerospace, ukuveliswa kwamandla, i-petrochemical, kunye nokuveliswa, ukukhusela nokubuyisela umgangatho, ukomeleza ukuxhathisa ukunxiba, kunye nokwandisa ubomi bezinto ezibalulekileyo. Ukusebenza kwayo okuphezulu kwiindawo ezinzima kwenza kube sisisombululo esithembekileyo kwizicelo ezifunayo.
Ukulungiswa okufanelekileyo komphezulu kubalulekile ukufikelela kwiziphumo ezizezona zilungileyo nge-NiCr 80/20ucingo lokutshiza olushushu. Umphezulu oza kugqunywa kufuneka ucocwe ngokucokisekileyo ukususa izinto ezingcolisa ezifana negrisi, ioyile, ubumdaka kunye neeoksidi. I-grit blasting kunye ne-aluminium oxide okanye i-silicon carbide iyacetyiswa ukuba ifezekise uburhabaxa bomphezulu be-50-75 microns. Ukuqinisekisa ukuba indawo ecocekileyo kunye nerhabaxa iphucula ukunamathela kwengubo yokutshiza ye-thermal, ekhokelela ekusebenzeni okuphuculweyo kunye nobomi obude.
