▌ Ụdị Alloy siri ike
A na-ekewa ụdị alloy siri ike a na-ahụkarị n'ụdị atọ dabere na nhazi na njirimara arụmọrụ: tungsten-cobalt, tungsten-titanium-cobalt, na tungsten-titanium-tantalum (niobium) alloys.Ihe kachasị eji eme ihe bụ tungsten-cobalt na tungsten-titanium-cobalt hard alloys.
(1)Tungsten-Cobalt Hard Alloy:
Ihe ndị bụ isi bụ tungsten carbide (WC) na cobalt.A na-egosipụta akararị ahụ site na koodu "YG", na-esote pasentị ọdịnaya cobalt.Dịka ọmụmaatụ, YG6 na-egosi tungsten-cobalt hard alloy nwere 6% cobalt ọdịnaya yana 94% tungsten carbide ọdịnaya.
(2)Tungsten-Titanium-Cobalt Alloy siri ike:
Ihe ndị bụ isi bụ tungsten carbide (WC), titanium carbide (TiC), na cobalt.A na-egosipụta akararị ahụ site na koodu "YT", na-esote pasentị ọdịnaya carbide titanium.Dịka ọmụmaatụ, YT15 na-egosi tungsten-titanium-cobalt hard alloy nwere 15% titanium carbide ọdịnaya.
(3)Tungsten-Titanium-Tantalum (Niobium) Alloy siri ike:
A na-akpọkwa ụdị alloy siri ike dị ka ihe siri ike zuru ụwa ọnụ ma ọ bụ ihe na-agbanwe agbanwe.Ihe ndị bụ isi bụ tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC), ma ọ bụ niobium carbide (NbC), na cobalt.A na-egosipụta akararị ahụ site na koodu "YW" (mkpụrụokwu nke "Ying" na "Wan," nke pụtara siri ike na nke zuru ụwa ọnụ na Chinese), na-esote ọnụọgụgụ.
▌ Ngwa nke Hard Alloy
(1)Ngwa Ngwa ịkpụ:
A na-eji alloy siri ike na-emepụta ihe eji egbutu ngwá ọrụ, gụnyere ngwá ọrụ ntụgharị, ndị na-egwe ọka, agụba planer, drills, wdg Tungsten-cobalt siri ike alloys na-adabara obere mgbawa machining nke ferrous na ndị na-abụghị ferrous ọla, dị ka nkedo ígwè. , nkedo ọla, na osisi ngwakọta.Tungsten-titanium-cobalt siri ike alloys dabara maka ogologo mgbawa machining nke ígwè na ndị ọzọ ferrous ọla.N'etiti alloys, ndị nwere ọdịnaya cobalt dị elu dị mma maka ịrụ ọrụ siri ike, ebe ndị nwere obere cobalt dị mma maka imecha.Alloys siri ike zuru ụwa ọnụ nwere ndụ ngwa ọrụ ogologo oge mgbe ị na-eji ihe siri ike ịkpụ dị ka igwe anaghị agba nchara.
(2)Ngwa Akpụkpọ
A na-ejikarị alloy siri ike mee ihe maka ịse oyi, oyi stamping anwụ, oyi extrusion anwụ, na oyi isi na-anwụ.
A na-edobe isi iyi oyi siri ike n'okpuru mmetụta ma ọ bụ ọnọdụ mmetụta siri ike.Ngwongwo ndị dị mkpa achọrọ bụ mmetụta siri ike nke ọma, mgbaji siri ike, ike ike ọgwụgwụ, ike na-ehulata, na ezigbo nguzogide eyi.Na-emekarị, a na-ahọrọ ihe dị n'etiti ma ọ bụ nnukwu ọdịnaya cobalt na ọkara ruo nke nwere nnukwu ọka.Ọkachamara ndị a na-ahụkarị gụnyere YG15C.
N'ozuzu, enwere mgbanwe n'etiti nguzogide iyi na ike siri ike na ihe alloy siri ike.Ịkwalite nguzogide iyi ga-eme ka ike sie ike belata, ebe ime ka ike sie ike ga-eduga n'ibelata.
Ọ bụrụ na akara ahọpụtara dị mfe ịmepụta n'oge mgbawa na mmebi na-eji, ọ bụ ihe kwesịrị ekwesị na-ahọrọ a ika na elu siri ike;Ọ bụrụ na akara ahọpụtara dị mfe ịmepụta n'oge na-emebi emebi na-eji, ọ bụ ihe kwesịrị ekwesị ịhọrọ akara nwere ike dị elu na nkwụsi ike ka mma.Ndị a akara ule: YG15C, YG18C, YG20C, YL60, YG22C, YG25C si n'aka ekpe gaa n'aka nri, ike na-ebelata, eyi iguzogide na-ebelata, ike na-mma;N'ụzọ megidere nke ahụ, ihe dị iche bụ eziokwu.
(3) Ngwá ọrụ nha na akụkụ ndị na-eguzogide iyi
A na-eji Tungsten carbide maka inlays elu abrasive na akụkụ nke ngwaọrụ nha, igwe na-egweri nke ọma, ntuziaka na ogwe ntụzịaka nke igwe igwe na-egweri etiti, yana akụkụ na-eguzogide ọgwụ dị ka ebe a na-akpụ ahịhịa.
