Tungsten Carbide-Nickel ọ bụ magnetik ma ọ bụ na-abụghị magnetik?

Tungsten carbide, nke a na-akpọkwa carbide cimented, bụ nke tungsten carbide ntụ ntụ na ntụ ntụ. Ihe na-ekekọta ntụ ntụ nwere ike ịbụ ntụ ntụ cobalt ma ọ bụ ntụ ntụ nickel. Mgbe anyị na-eji ntụ ntụ cobalt dị ka ihe nkedo n'ichepụta ngwaahịa tungsten carbide, anyị ga-enwe ule magnetik cobalt iji nyochaa ọnụọgụ cobalt na tungsten carbide. Ya mere, ọ bụ n'ezie na tungsten carbide-cobalt bụ magnetik. Otú ọ dị, tungsten carbide-nickel abụghị magnetik.

Ị nwere ike iche na ọ bụ ihe a na-apụghị ikweta ekweta na mmalite. Ma ọ bụ eziokwu. Tungsten carbide-nickel bụ ụdị ihe na-abụghị magnetik nwere mmetụta dị mma. N'isiokwu a, ọ ga-amasị m ịkọwara gị nke a.

Dị ka ọla edo edo edo, cobalt na nickel bụ magnetik. Mgbe ịgwakọta, ịpị, na singing na tungsten carbide ntụ ntụ, tungsten carbide-cobalt ka bụ magnetik, ma tungsten carbide-nickel abụghị. Nke a bụ n'ihi na atom tungsten na-abanye n'ime lattice nke nickel ma gbanwee ntụgharị eletrọn nke nickel. Mgbe ahụ igwe eletrọn nke tungsten carbide nwere ike ịkagbu. Ya mere, tungsten carbide-nickel enweghị ike ịdọrọ magnet. Na ndụ anyị kwa ụbọchị, igwe anaghị agba nchara na-etinyekwa ụkpụrụ a.

Gịnị bụ eletrọn spin? Igwe eletrọn bụ otu n'ime ihe atọ dị n'ime elektrọn. Ihe abụọ ndị ọzọ bụ oke na ụgwọ nke eletrọn.

Ihe ka ọtụtụ n'ime ihe mejupụtara bụ ụmụ irighiri ihe, ụmụ irighiri ihe mejupụtara atom, na atom bụ nke nuclei na electrons. Na atom, eletrọn na-agbagharị mgbe niile ma na-atụgharị gburugburu oghere. Mmegharị ndị a nke eletrọn nwere ike ịmepụta magnetism. N'ihe ụfọdụ, electrons na-aga n'akụkụ dị iche iche, mmetụta magnetik nwere ike ịkagbu nke mere na ihe ndị a abụghị magnetik n'okpuru ọnọdụ nkịtị.

Agbanyeghị, ụfọdụ ihe ferromagnetic dị ka ígwè, cobalt, nickel, ma ọ bụ ferrite dị iche. Enwere ike ịhazi igwe eletrọn ha n'obere ebe iji mepụta ngalaba magnetik. Nke a bụ ihe mere cobalt na nickel a sachara ọcha ji bụrụ magnetik na magnet nwere ike dọta ya.

Na tungsten carbide-nickel, atom tungsten na-emetụta ụda eletrọn nke nickel, yabụ tungsten carbide-nickel abụghị magnetik ọzọ.

Dịka ọtụtụ nsonaazụ sayensị siri kwuo, tungsten carbide-nickel nwere nguzogide corrosion dị elu na nguzogide oxidation karịa tungsten carbide-cobalt. Na sintering, nickel nwere ike na-etolite a mmiri mmiri mmiri n'ụzọ dị mfe, nke nwere ike inye mma mmiri ike na tungsten carbide n'elu. Kedu ihe ọzọ, nickel dị ọnụ ala karịa cobalt.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe.
