Iimpawu eziphambili zeCarbide eneCemented
I-carbide ene-cemented yi-alloy material eyenziwe nge-compound eqinile yentsimbi ephikisayo kunye nentsimbi ye-matrix ngokusebenzisa inkqubo ye-metallurgy powder. Ngenxa yokuba izithako eziqulethwe kwi-powder metallurgy kunye nendlela yokulungiselela ziyahluka. Iimpawu ze-carbide ene-cemented zihlukile. Makhe sixoxe ngeempawu eziphambili ze-carbide ene-cemented kweli nqaku.
1. Akukho sikhokelo kwi-carbide enesamente. I-carbide enesamente yenziwe nge-powder pressure sintering. Ngenxa yokuba inkqubo yokuphosa ingasetyenziswanga, akukho mahluko kubuninzi phakathi komgangatho ophezulu kunye nokwakheka kwangaphakathi, ngaloo ndlela kupheliswe umahluko womsebenzi womatshini onokuthi ubangelwe ngumahluko woxinaniso.
2. I-carbide ene-cemented ayinayo ingxaki yonyango lokushisa. Umsebenzi womatshini we-carbide ene-cemented awutshintshi ngokufudumeza kunye nokupholisa, uphenjelelwa kuphela ngoxinzelelo lwe-thermal ngexesha lokufudumala okanye ukupholisa. Ngoko ke, ukucwangciswa kwangaphambili kwe-carbide ene-cemented kufuneka kuqhutywe phambi kwenkqubo ye-sintering. Emva kwe-sintering, inokusebenza kuphela ngezixhobo zedayimani. Umsebenzi womatshini we-carbide ene-cemented ikakhulu unqunywe ngumlinganiselo we-cobalt kunye ne-particle size ye-tungsten carbide.
3. Umlinganiselo wePoisson we-cemented carbide yi-0.21 ~ 0.24. Ngoko ke, i-samente ye-carbide mold ye-diameter yangaphakathi inotshintsho oluncinci kakhulu kunobumba lwensimbi phantsi kwesenzo soxinzelelo. Ngoko ke, ubungakanani bemveliso ye-carbide ene-cemented isondele kakhulu kubukhulu besikhunta.
4. I-Carbide inamandla aphezulu oxinzelelo. Umxholo we-cobalt unokumisela amandla oxinzelelo. Amandla oxinzelelo lweemveliso ze-carbide ezine-cobalt ephantsi zinokufikelela ngaphezulu kwe-6000Mpa, ephantse ibe kabini yentsimbi.
5. I-carbide ene-cemented ine-coefficient ephantsi yokwandiswa kwe-thermal. Abantu kufuneka bathathele ingqalelo le ngongoma kuyilo lwe-carbide mold kunye nokuveliswa.
6. I-thermal conductivity ephezulu. I-thermal conductivity ye-carbide ene-cemented iphindwe kathathu ngaphezu kwensimbi engenasici.
7. I-elastic deformation kunye ne-plastic deformation ye-cemented carbide incinci.
8. Uninzi lweempawu ezidumileyo ze-carbide ene-cemented bubunzima bayo obuphezulu kunye nokumelana nokugqoka okuphezulu. Ixesha lokusetyenziswa kwe-tungsten carbide lide kunentsimbi engenasici.
Okwangoku, i-carbides ene-cemented esetyenziswa kwi-molds yasekhaya iquka i-tungsten kunye ne-cobalt.
