Izakhiwo zomzimba ze-Tungsten Carbide

I-Tungsten carbide, eyaziwa nangokuthi i-cemented carbide, ingenye yezinto ezisetshenziswa embonini yesimanje. Imikhiqizo ye-Tungsten carbide ihlale inezindawo zokuqina okuphezulu, ukumelana nokugqoka, namandla amahle okuqhekeka okunqamulayo. Izakhiwo eziningi zomzimba zithintwa inani le-cobalt ne-carbon, usayizi wokusanhlamvu, kanye ne-porosity.

Ukuminyana

Kusukela esicini somzimba, ukuminyana kwemikhiqizo ye-tungsten carbide isilinganiso sobunzima bayo nomthamo wabo. Ukuminyana kungahlolwa ngebhalansi yokuhlaziya. Ubuningi be-tungsten carbide bungathinteka ngobuningi kanye nomthamo we-tungsten carbide. Lokho kusho ukuthi yonke into engathinta ubukhulu noma ivolumu nayo ingathinta ukuminyana.

Inani labo lingathinta ukuminyana kwe-tungsten carbide. Ubuningi be-cobalt bukhulu kunobuningi bekhabhoni. Ngakho-ke lapho i-cobalt ingeziwe ku-tungsten carbide, ukuminyana okuphezulu kwe-tungsten carbide kuba. Ngokuphambene nalokho, i-carbon eyengeziwe iba ku-tungsten carbide, ukuminyana okuphansi kwe-tungsten carbide. I-porosity ingase futhi ithinte ukuminyana. I-porosity ephezulu idala ukuminyana okuphansi.

Ukuqina

Ukwahlulela ubulukhuni bempahla kufana nokumelana kwayo nokugqoka. Umkhiqizo we-tungsten carbide onobulukhuni obuphezulu ungabekezelela umthelela futhi ugqoke kangcono, ngakho-ke ungasebenza isikhathi eside.

Njenge-bonder, i-cobalt encane ibangela ubulukhuni obungcono. Futhi i-carbon ephansi ingenza i-tungsten carbide ibe nzima. Kodwa i-decarbonization ingenza i-tungsten carbide ibe lula ukuyilimaza. Ngokuvamile, i-tungsten carbide enhle izokwandisa ubulukhuni bayo.

Amandla okuqhekeka okuguquguqukayo

Amandla okuqhekeka okuguquguqukayo yikhono le-tungsten carbide ukumelana nokugoba. I-Tungsten carbide enamandla angcono wokuqhekeka aguquguqukayo inzima kakhulu ukuyonakalisa ngaphansi komthelela. I-tungsten carbide enhle inamandla angcono okuqhekeka okuphambene. Futhi lapho izinhlayiya ze-tungsten carbide zisakazwa ngokulinganayo, i-transverse ingcono, futhi i-tungsten carbide akulula ukuyilimaza.

Ngaphandle kwalezi zakhiwo ezintathu ezibonakalayo, kusekuningi okufanele sikwazi, futhi zingahlolwa ngemishini.

Abasebenzi bokuhlola ikhwalithi bahlale behlola isakhiwo se-metallographic ngaphansi kwesibonakhulu se-metallurgical. Lapho i-cobalt eyeqile igxila endaweni, izokwakha ichibi le-cobalt.

Singakwazi ukwazi inani le-cobalt ngokuhlola uzibuthe we-cobalt nge-cobalt magnetic tester. Futhi amandla enkambu ephoqelelayo angabuye ahlolwe ngomphoqeleli.

Kusukela kulezi zakhiwo ezibonakalayo, kusobala ukuthi i-tungsten carbide inezakhiwo eziningi kanye nezinzuzo zokumba izimayini, ukubhoreka, ukusika, nokumba.

Uma ufuna ukwazi ulwazi olwengeziwe kanye nemininingwane, ungasithinta ngenombolo yocingo noma nge-imeyili kwesokunxele, noma Sithumele Imeyili ezansi kuleli khasi.
