Mokhoa oa ho etsa tlhahlobo ea metallographic ka mor’a ho tima sebōpi sa ho futhumatsa ka induction?

Tlhahlobo ea Metallographic ea likarolo tsa tšepe tsa pearlite ductile ka mor’a ente e futhumatsang mollo ho tima ho tla etsoa ho latela JB/T 9205-2008 “Induction futhumatsang sebōpi se timang tlhahlobo ea metallographic ea likarolo tsa tšepe tsa pearlite ductile”

1) Kamora hore tšepe ea pearlitic ductile e tingoe ka har’a libopi tse futhumatsang tse phahameng le tse mahareng le mocheso o tlase oa mocheso (W200T), lisampole tsa metallographic li tla nkuoa bohareng ba sebaka sa ho tima kapa sebakeng se boletsoeng ke tekheniki. maemo.

2) Ka mor’a ho sila, sampuli ea metallographic e kenngoa ka tharollo ea joala e nang le 2% ho ea ho 5% ea nitric acid ka molumo ho fihlela lera le hlakileng le thata le bontšoa.

3) Ho ea ka litaelo tsa lihlopha tsa microstructure tse bontšitsoeng ho Lethathamo la 6.2 le chate ea likarolo tsa microstructure ho JB / T 9205-2008, etsa tlhahlobo ea metallographic. Har’a bona, sehlopha sa 3 ho isa ho sa 6 se na le mangolo; ha ho na le litlhoko tse khethehileng, li tla kenngoa ts’ebetsong ho latela litokomane tse amehang tsa tekheniki.

Letlapa la 6-2 Tlhaloso ea likarolo tsa microstructure ea pearlite ductile iron castings ka mor’a ho tima sebōping sa ho futhumatsa ka induction
