Otu esi emepụta Tungsten Carbide
Otu esi emepụta Tungsten Carbide
Anyị niile maara na carbide alloys sitere na tungsten carbide, mana ị maara ihe nzuzo nke otu esi emepụta ya? Akụkụ a nwere ike ịgwa gị azịza ya. Mmepụta nke carbide cimented bụ ịgwakọta ntụ ntụ carbide na ntụ ntụ n'otu akụkụ, na-agbanye n'ụdị dị iche iche, wee bụrụ ọkara-sintered. Okpomọkụ na-ekpo ọkụ bụ 1300-1500C.
Mgbe ị na-emepụta carbide cemented, ntụ ntụ akụrụngwa ahọpụtara nwere nha n'etiti 1 na 2 microns, ịdị ọcha dị oke elu. A na-agwakọta ntụ ọka akụrụngwa dị ka usoro a kapịrị ọnụ si dị, ọ nwere ike iru ọkwa dị iche iche dịka nha dị iche iche nke WC na ntụ ntụ. Mgbe ahụ, a na-etinye ihe ndị ahụ na igwe ihe igwe mmiri mmiri ka ọ na-egweri ha maka ime ka ha gwakọta ma gwerie ha. Mgbe ihicha na sieving, a na-agbakwunye onye na-emepụta ihe, na ngwakọta na-akpọnwụ na sieve. Na-esote, mgbe a na-agbanye ngwakọta ahụ ma pịa ya, na-ekpo ọkụ n'akụkụ ebe mgbaze nke metal binder (1300-1500 ° C), usoro ahụ siri ike na ihe nkedo ga-eme ka eutectic alloy. Mgbe jụrụ oyi, a na-emepụta ihe siri ike. Isi ike nke carbide cimented na-adabere na ọdịnaya WC na nha ọka, ya bụ, ọnụ ọgụgụ ka ukwuu nke WC na ọka dị mma, na-esiwanye ike karị. A na-ekpebi ike nke ngwá ọrụ carbide site na ígwè njikọ. Ihe dị elu nke ọdịnaya nke ígwè njikọ, otú ahụ ka ike na-ehulata dị ukwuu.
Ị chere na emechara ngwaahịa ahụ mgbe ọ jụrụ oyi?
Azịza ya bụ mba! Mgbe nke ahụ gasịrị, a ga-eziga ya maka ọtụtụ ule. Ngwaahịa Tungsten carbide nwere ike igosipụta ọdịiche dị na akụrụngwa akụrụngwa na akụrụngwa kemịkalụ, akụkụ anụ ahụ, yana usoro ọgwụgwọ okpomọkụ. Ya mere, a na-eji ule siri ike na-eme ihe n'ọtụtụ ebe na nyocha nke ihe onwunwe carbide, nke nwere ike na-elekọta nhazi nke usoro ọgwụgwọ okpomọkụ na nyocha nke ihe ọhụrụ. Nchọpụta siri ike nke tungsten carbide na-ejikarị Rockwell hardness tester nwalee ụkpụrụ isi ike HRA. Nnwale ahụ nwere ọdịdị siri ike na nhazi akụkụ nke mpempe ule na arụmọrụ dị elu.
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.
