Kedu ka esi eme ntinye ntụgharị?
Ihe ntinye na-atụgharị bụ ihe eji egbutu ihe eji eme ihe maka imepụta ígwè, igwe anaghị agba nchara, na ihe ndị ọzọ. Ihe ntinye na-atụgharị nwere ezigbo nguzogide okpomọkụ ma na-eyi nkwụsi ike, n'ihi ya, a na-ahụ ha n'ọtụtụ ngwá ọrụ na igwe. Ihe fọrọ nke nta ka ọ bụrụ ntinye ntụgharị bụ nke ihe kachasị sie ike n'ụwa, tungsten carbide. N'isiokwu a, a ga-ewebata usoro mmepụta nke ịtụgharị ntinye.
Gwakọta ntụ ntụ tungsten carbide na ntụ ntụ. Iji mee ntinye ntụgharị, ụlọ ọrụ anyị ga-azụta 100% akụrụngwa tungsten carbide ntụ ntụ ma tinye ntụ ntụ cobalt na ya. Ndị na-ekekọta ihe ga-ejikọta akụkụ carbide tungsten ọnụ. A na-azụta akụrụngwa niile, gụnyere tungsten carbide ntụ ntụ, ntụ ntụ, na ihe ndị ọzọ, n'aka ndị na-ebubata ya. Na akụrụngwa a ga-enyocha nke ọma na ụlọ nyocha.
A na-egwe ọka mgbe niile n'igwe igwe igwe nwere mmiri mmiri dị ka mmiri na ethanol. Usoro a ga-ewe ogologo oge iji nweta ụfọdụ nha ọka.
A ga-awụsa slurry a gweriri n'ime igwe na-agba mmiri. A ga-agbakwunye gas na-adịghị arụ ọrụ dị ka nitrogen na okpomọkụ dị elu iji wepụ mmiri mmiri. Ntụ ọka, mgbe ịgbasachara, ga-abụ nkụ, nke ga-erite uru site na ịpị na sintering.
N'oge ịpị, ntinye ntụgharị tungsten carbide ga-ejikọta ya na-akpaghị aka. Ihe ntinye ntụgharị a na-agbanye na-esighi ike ma dị mfe imebi. Ya mere, a ga-etinye ha n'ime ọkụ ọkụ. Okpomọkụ na-ekpo ọkụ ga-abụ ihe dịka 1,500 ° C.
Mgbe emechara, ihe ntinye ga-abụ ala iji nweta nha ha, geometry, na ndidi. A ga-ekpuchi ọtụtụ ihe ntinye site na ntinye uzuoku kemịkalụ, CVD, ma ọ bụ ntinye ikuku anụ ahụ, PVD. Usoro CVD bụ inwe mmeghachi omume kemịkalụ n'elu ihe ntinye na-atụgharị iji mee ka ntinye ahụ sie ike ma sie ike karị. N'ime usoro PVD, a ga-etinye ntinye ntụgharị nke tungsten carbide n'ime ihe ndozi, ihe mkpuchi ahụ ga-apụkwa n'elu ihe ntinye.
Ugbu a, a ga-enyocha ntinye nke tungsten carbide ọzọ wee kwakọba ya iziga ndị ahịa.
Ọ bụrụ na ị nwere mmasị na ntinye ntụgharị tungsten carbide ma chọọ ozi ndị ọzọ na nkọwapụta, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala ibe.
