Kedu ihe dị iche n'etiti simenti carbide na tungsten ígwè?

Tungsten steel: Ngwaahịa emechara nwere ihe dịka 18% tungsten alloy steel. Tungsten ígwè bụ nke siri ike alloy, nke a makwaara dị ka tungsten-titanium alloy. Isi ike bụ 10K Vickers, nke abụọ naanị diamond. N'ihi nke a, ngwaahịa nchara tungsten (kacha elekere tungsten steel) nwere njirimara nke anaghị adị mfe eyi. A na-ejikarị ya eme ihe na ngwaọrụ lathe, mmetụta akuakuzinwo ibe n'ibe, iko cutter ibe n'ibe, tile cutters. Ọ dị ike, ọ dịghịkwa atụ egwu ịnwụ anwụ, ma ọ na-agbaji agbaji.

Carbide cimented: bụ nke ubi uzuzu metallurgy. Carbide cimented, nke a makwaara dị ka seramiiki ígwè, bụ seramiiki nwere ihe ụfọdụ nke ígwè, nke a na-eji ígwè carbides (WC, TaC, TiC, NbC, wdg) ma ọ bụ metal oxides (dị ka Al2O3, ZrO2, wdg) dị ka isi ihe, na ihe kwesịrị ekwesị ego nke metal ntụ ntụ (Co, Cr, Mo, Ni, Fe). A na-eji Cobalt (Co) mee ihe na-emekọ ihe na alloy, ya bụ, n'oge usoro nhazi, ọ nwere ike gbaa gburugburu tungsten carbide (WC) ntụ ntụ ma jikọta ọnụ. Mgbe ọ dị jụụ, ọ na-aghọ carbide cemented. (Mmetụta dị ka simenti na kọmpụta). Ọdịnaya na-abụkarị: 3%-30%. Tungsten carbide (WC) bụ isi akụrụngwa na-ekpebi ụfọdụ metal Njirimara nke a cemented carbide ma ọ bụ cermet, na-aza 70%-97% nke mkpokọta components (oke arọ). A na-eji ya n'ọtụtụ ebe na-eguzogide iyi, oke okpomọkụ na-eguzogide, akụkụ na-eguzogide corrosion ma ọ bụ mma na isi ngwá ọrụ na gburugburu ebe ọrụ siri ike.

Tungsten ígwè bụ nke simenti carbide, ma simenti carbide bụchaghị tungsten ígwè. N'oge a, ndị ahịa nọ na Taiwan na mba ndịda ọwụwa anyanwụ Eshia na-amasị iji okwu tungsten steel. Ọ bụrụ na ị gwa ha okwu n'ụzọ zuru ezu, ị ga-achọpụta na ọtụtụ n'ime ha ka na-ezo aka na carbide ciment.

Ihe dị iche n'etiti tungsten ígwè na carbide cimented bụ na tungsten ígwè, nke a na-akpọkwa ígwè dị elu ma ọ bụ ngwá ọrụ ígwè, na-eme ka ọ bụrụ na ọ na-agbakwunye tungsten ígwè dị ka tungsten raw material na-agbaze nchara na-eji teknụzụ ígwè, nke a makwaara dị ka ígwè dị elu ma ọ bụ ngwá ọrụ ígwè, na ọdịnaya tungsten ya na-abụkarị 15-25%; Ebe carbide cimented na-eme site na sintering tungsten carbide dị ka isi ahụ na cobalt ma ọ bụ ndị ọzọ bonding ọla na-eji ntụ ntụ metallurgy technology, na tungsten ọdịnaya na-emekarị karịa 80%. N'ikwu ya n'ụzọ dị mfe, ihe ọ bụla nwere ike karịa HRC65 ma ọ bụrụhaala na ọ bụ alloy nwere ike ịkpọ cemented carbide, na tungsten steel bụ ụdị carbide cemented nwere ike dị n'etiti HRC85 na 92, a na-ejikarị eme mma.
