● Ogwe ahụ dum enweghị ntụpọ ma ọ bụ nkwonkwo n'ogologo ya niile.

Isi Ihe Ndị Dị Mkpa Banyere Njikwa Ogo

● Ihe mejupụtara kemịkalụ: Nyocha spectrometer (SPECTRO) nke a na-eme na okpomọkụ ọ bụla; ihe niile e ji achọpụta ihe (P, Fe, Sb, Bi, wdg) na-achịkwa ruo 50% nke oke ọkọlọtọ ma ọ bụ sie ike.
● Njirimara igwe: Ụkpụrụ nkịtị maka ogwe Φ≥200mm: Ike nrụgide ≥450 MPa, ike mmepụta 0.2% ≥200 MPa, ogologo ≥15%, ike siri ike HB120–180 (ekwe nkwa nke ọma).
● Ịdị mma dị n'ime: Nnwale ultrasonic 100% dịka ọkwa ASTM B594 Klas A ma ọ bụ SEP 1921 E/e si dị site na iji nyocha 6–10 MHz. Akụkọ UT zuru oke na foto macro/microstructure dị maka otu mmanya ma ọ bụrụ na a rịọ ya.
● Ndozi nha: Ndozi dayameta ±0.5 ruo ±1.5 mm (ka mma karịa H11), ịdị larịị ≤1 mm/m, ntachi obi ogologo ịkpụ ±20 mm.
● Mmecha elu: A tụgharịrị nke ọma mgbe e wepụsịrị ya, oke iru ala Ra ≤3.2 μm, enweghị mgbawa, ihe ndị dị na ya, ma ọ bụ ntụpọ oroma-peel.

Ntụaka ọkọnọ

● Nnukwu ihe mkpuchi mmiri (otu CuSn10Zn2 bars 3–5 tọn)
● Ndị na-eme mkpọtụ sekit voltaji dị elu (CuSn6/CuSn8)
● Sistemụ ọkpọkọ mmiri mmiri (obosara C51900 buru ibu)
● Bronze tin-phosphor siri ike nke nwere ike dị elu maka njem ụgbọ okporo ígwè na ngwa ike ifufe
