Ipropathi ebonakalayo ye-tungsten carbide

Itekhnoloji yanamhlanje inoluhlu olubanzi lokusebenziseka kwi-alloy ekhethekileyo tungsten-cobalt. Kutheni ithandwa kangaka nje? Nazi ezinyeiimpawu zomzimba yetungsten carbide. Emva kokufunda esi sicatshulwa uya kwazi iinkcukacha ngakumbi ngayo.

Ukuqina.

Sonke siyazi ukuba idayimani yenye yezona zinto zinzima zendalo emhlabeni. Ngelixa ukuqina kwe-tungsten carbide kukwesibini kwidayimane.Ukuqina yenye yezinto eziphambili zomatshini we-carbide enesamente. Ngokunyuka komxholo we-cobalt kwi-alloy okanye ukwanda kwe-carbide ubungakanani bengqolowa, ubunzima be-alloy buyancipha. Ngokomzekelo, xa umxholo we-cobalt we-industrial WC-Co ukhuphuka ukusuka kwi-2% ukuya kwi-25%, ubunzima be-alloy buyancipha ukusuka kwi-93 ukuya malunga ne-86. Kuzo zonke iipesenti ezi-3 zokunyuka kwe-cobalt, ubunzima be-alloy buyancipha nge-1 degree. Ukucoca ubungakanani beenkozo ze-tungsten carbide kunokuphucula ngokufanelekileyo ubulukhuni be-alloy.

Ukugoba amandla.

Njengokuqina, amandla okugoba yenye yezona zinto ziphambili ze-carbide enesamente. Kukho izinto ezininzi ezinzima ezichaphazela amandla okugoba e-alloy, Ngokuqhelekileyo, amandla okugoba e-alloy ayanda ngokunyuka komxholo we-cobalt. Nangona kunjalo, xa umxholo we-cobalt udlula i-25%, amandla okugoba ayancipha ngokunyuka komxholo we-cobalt. Ngokubhekiselele kwi-alloy ye-WC-Co yoshishino, amandla okugoba e-alloy ahlala enyuka ngokunyuka komxholo we-cobalt kuluhlu lwe-0-25%.

Amandla acinezelayo.

Amandla oxinzelelo lwe-cemented carbide abonisa amandla okumelana nomthwalo woxinzelelo.ngokwanda kwekobhalitiumxholo kunye nokwandisa kunye nobukhulu beenkozo zesigaba se-tungsten carbide kwi-alloy tamandla acinezelayo e-WC-Co ingxubevange ayancipha. Ke ngoko, i-alloy-grain-alloy enomxholo ophantsi we-cobalt inamandla aphezulu oxinzelelo.

Ukuqina kwempembelelo.

Ukuqina kwempembelelo isalathiso sobugcisa esibalulekileyo se-alloys yemigodi, kwaye inokubaluleka okusebenzayo kwizixhobo zokusika ezingapheliyo phantsi kweemeko ezinzima. Ukuqina kwempembelelo ye-WC-Co alloy inyuka ngokunyuka komxholo we-cobalt kunye nobukhulu beenkozo ze-tungsten carbide. Ngoko ke, ininzi ye-alloys yemigodi i-coarse-grained alloys enomxholo ophezulu we-cobalt.

Ukugcwala kwemagneti. 

TUkuqina kwemagnethi ye-alloy kuyanda ngokunyuka kwendawo yangaphandle yemagnethi. xa ubukhulu bemagnethi bufikelela kwixabiso elithile, ukunyanzeliswa kwamagnetic akusayi kunyuka, oko kukuthi, i-alloy ifikelele kwi-saturation magnetic. Ixabiso le-magnetic saturation ye-alloy lihambelana kuphela nomxholo we-cobalt kwi-alloy. Ngoko ke, ukuchithwa kwamagnetic kungasetyenziselwa ukujonga ukubunjwa okungonakalisi kwe-alloy okanye ukuchonga ukuba kukho i-non-magnetic η l isigaba kwi-alloy kunye nokubunjwa okwaziwayo.

Imodyuli ye-elastic.

NgokubaWCinemodyuli ephezulu elastiki,njengeWC-Co. I-elastic modulus iyancipha ngokunyuka komxholo we-cobalt kwi-alloy, kwaye ubukhulu bengqolowa ye-tungsten carbide kwi-alloy ayinayo impembelelo ecacileyo kwi-elastic modulus.Wngokunyuka kobushushu benkonzo tyena imodyuli elastiki yealloyi iyancipha.

I-coefficient yokwandisa i-Thermal.

I-coefficient yokwandiswa komgca we-WC-Co i-alloy inyuka ngokunyuka komxholo we-cobalt. Nangona kunjalo, i-coefficient yokwandiswa kwe-alloy iphantsi kakhulu kuneyentsimbi, eya kubangela uxinzelelo olukhulu lwe-welding xa isixhobo se-alloy sifakwe kwaye sifakwe. Ukuba amanyathelo okupholisa kancinane akathathwa, i-alloy iya kuhlala iqhekeka.

Lilonke, iTungsten carbide inomsebenzi ophezulu kwiipropathi zayo zomzimba. Ngenxa yoko, uTiimpawu ezifanelekileyo ezibonakalayo ze-carbide enesamente aziphelelanga aphoabo. Tiimpawu zemathiriyeli ezineendlela ezahlukeneyo zokusetyenziswa okukhethekileyo nazo ziya kwahluka. Ndifuna ukwazi ngakumbi ngetungsten carbide wamkelekile ukuba usilandele.
