Metallographic Structure maka enamel na nkedo ígwè

A na-emepụta ihe eji esi nri nkedo nke nwere Enamel site na nhazi nke usoro nkedo nke gụnyere ferrite na pearlite. Ferrite bụ akụkụ dị nro na nke na-agbanwe agbanwe, ebe pearlite na-ejikọta ferrite na cementite, na-enye ya ike na ike.

N'ime usoro nke itinye mkpuchi enamel na nkedo ígwè, ọ dị oke mkpa ịghọta nhazi metallographic iji hụ na nrapanye na ịdịte aka kacha mma. Bọọgụ blọgụ a ga-enyocha usoro nhazi nke igwe nkedo, na-elekwasị anya na ọkwa nke na-enye aka na ntinye nke ọma nke mkpuchi enamel.

1. Isi oyi akwa: Igwe ntụ ntụ ntụ
Igwe nkedo a na-eji maka mkpuchi enamel na-abụkarị ígwè nkedo isi awọ. A maara ụdị nkedo a maka nnukwu carbon carbon, nke na-enye ya ike dị mma ma na-eyi nguzogide. A na-ejikwa ya mara ya site na flakes graphite, nke na-enye ezigbo conductivity thermal ma belata brittleness.
2. Nkwadebe mkpụrụ: Ịgba aja na nhicha
A ghaghị ịkwado elu igwe nkedo iji mee ka nrachi kwesịrị ekwesị nke mkpuchi enamel. Nke a na-agụnyekarị ịgbawa ájá iji wepụ ihe ọ bụla adịghị ọcha ma ọ bụ ihe ndị na-emerụ emerụ, na-esochi ya nke ọma iji hụ na ebe dị ọcha ma dị mma maka enamel na-agbaso.
Maka mkpuchi enamel, ígwè nkedo kwesịrị inwe nha nha nha nke ferrite na pearlite. Ngwakọta a na-enye ntọala siri ike maka enamel na-agbaso ma na-eme ka ọ dị ogologo oge nke mkpuchi ahụ. Oge ferrite na-enyere aka n'inweta na ikesa okpomọkụ nke ọma, ebe oge pearlite na-agbakwụnye ike na iguzogide iyi.

Na mgbakwunye na ferrite na pearlite, ihe ndị ọzọ dị ka carbon, silicon, na manganese na-ekere òkè dị mkpa. Ọdịnaya carbon kwesịrị ịdị agafeghị oke iji nye ike ma gbochie nbibi. Silicon na-enyere aka na ntinye nke mkpuchi enamel, ebe manganese na-eme ka ike zuru ezu na ike nke nkedo ahụ dịkwuo elu.
Iji chịkọta ọnụ, ihe mejupụtara dị mma maka ihe nkedo nke nkedo nwere mkpuchi enamel gụnyere nha nha nha nke ferrite na pearlite, ọdịnaya carbon na-agafeghị oke, yana ọnụnọ silicon na manganese. Ngwakọta a na-eme ka mkpuchi enamel na-adịgide adịgide, ọbụna nkesa okpomọkụ, na arụmọrụ na-adịte aka nke cookware
