Uyenza njani iTungsten Carbide

Sonke siyazi ukuba i-carbide alloys yenziwe kwi-tungsten carbide, kodwa ngaba uyayazi imfihlelo yendlela yokuvelisa? Eli nqaku liza kukunika impendulo. Ukuveliswa kwe-carbide ene-cemented kukuxuba i-carbide powder kunye ne-bond powder kwinqanaba elithile, ucinezele kwiimo ezahlukeneyo, kwaye emva koko u-semi-sintered. Ubushushu be-sintering yi-1300-1500 ° C.

Xa kuveliswa i-carbide ene-cemented, i-powder eluhlaza ekhethiweyo inobungakanani be-particle phakathi kwe-1 kunye ne-2 microns, kwaye ubunyulu buphezulu kakhulu. I-powders yezinto eziluhlaza zixutywe ngokomlinganiselo ochaziweyo wokubunjwa, unokufikelela kumabakala ahlukeneyo ngokwemilinganiselo eyahlukeneyo ye-WC kunye ne-bond powder. Emva koko i-medium yongezwa kwi-mill yebhola emanzi ukuze imanzi-yigaye ukuze idibanise ngokupheleleyo kwaye icolile. Emva kokumisa kunye ne-sieving, i-agent agent yongezwa, kwaye umxube womile kwaye uhlanjululwe. Emva koko, xa umxube uhlanjululwe kwaye ucinezelekile, kwaye ushushu kufuphi nendawo yokuncibilika kwensimbi ye-binder (1300-1500 ° C), isigaba esinzima kunye nentsimbi ye-binder iya kwenza i-eutectic alloy. Emva kokupholisa, yonke into eqinileyo yenziwa. Ubunzima be-carbide ene-cemented buxhomekeke kumxholo we-WC kunye nobukhulu bengqolowa, oko kukuthi, ubuninzi be-WC kunye ne-grains ecolekileyo, ubunzima obukhulu. Ukuqina kwesixhobo se-carbide kunqunywe yintsimbi yebhondi. Ukuphakama komxholo wentsimbi yebhondi, amandla amakhulu okugoba.

Ngaba ucinga ukuba emva kokupholisa imveliso yenziwe ngokupheleleyo?

Impendulo nguhayi! Emva koko, iya kuthunyelwa kwiimvavanyo ezininzi. Iimveliso ze-tungsten ze-carbide zingabonakalisa umahluko kwiipropati zomatshini kumacandelo ekhemikhali, izakhiwo zezicubu, kunye nenkqubo yokunyanga ukushisa. Ngoko ke, uvavanyo lobunzima lusetyenziswa ngokubanzi ekuhloleni izakhiwo ze-carbide, ezinokubeka iliso ngokuchaneka kwenkqubo yonyango lokushisa kunye nophando lwezinto ezintsha. Ukufunyanwa kobulukhuni be-tungsten carbide ikakhulu kusetyenziswa i-Rockwell hardness tester ukuvavanya amaxabiso obunzima be-HRA. Uvavanyo lunemilo eyomeleleyo kunye nokuguquguquka kwe-dimensional yesiqwenga sovavanyo kunye nokusebenza okuphezulu.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
