Babban Halayen Cemented Carbide

Carbide da aka yi da siminti wani abu ne mai ƙarfi wanda aka yi da ƙarfe mai ƙarfi na ƙarfe mai jujjuyawa da ƙarfe matrix ta hanyar aikin ƙarfe na foda. Domin abubuwan da ke ƙunshe a cikin ƙarfe na foda da hanyar shirye-shiryen sun bambanta. Halayen simintin carbide sun bambanta. Bari mu tattauna manyan halaye na ciminti carbide a cikin wannan labarin.

1. Babu shugabanci a cikin siminti carbide. Carbide da aka yi da siminti an yi shi da matsa lamba na foda. Saboda ba a yi amfani da tsarin simintin gyare-gyare ba, babu wani bambanci a cikin yawa tsakanin saman saman da abun da ke ciki, don haka yana kawar da bambancin aikin injiniya na gida wanda zai iya haifar da bambanci mai yawa.

2. Carbide da aka yi da siminti ba shi da matsalar maganin zafi. Ayyukan injiniya na ciminti carbide ba ya canzawa ta hanyar dumama da sanyaya, kawai yana rinjayar yanayin zafi yayin dumama ko sanyaya. Sabili da haka, dole ne a aiwatar da aikin da aka yi da carbide da aka yi da siminti kafin aikin simintin. Bayan sintering, zai iya aiki da kayan aikin lu'u-lu'u kawai. Aikin injiniya na siminti carbide an ƙaddara shi ne ta hanyar adadin cobalt da girman barbashi na tungsten carbide.

3. Matsakaicin Poisson na simintin carbide shine 0.21 ~ 0.24. Saboda haka, diamita na ciki na siminti na siminti yana da ɗan ƙaramin canji fiye da ƙirar ƙarfe a ƙarƙashin aikin sarrafa damuwa. Don haka, girman samfurin carbide da aka yi da siminti yana kusa da girman ƙirar.

4. Carbide yana da ƙarfin matsawa. Abubuwan da ke cikin cobalt na iya ƙayyade ƙarfin matsawa. Ƙarfin ƙarfi na samfuran carbide da aka ƙera tare da ƙaramin cobalt na iya kaiwa fiye da 6000Mpa, wanda kusan sau biyu ne na ƙarfe.

5. Carbide da aka yi da siminti yana da ƙarancin haɓakar haɓakar thermal. Ya kamata mutane suyi la'akari da wannan batu a cikin ƙira da ƙira na carbide.

6. High thermal watsin. Thermal conductivity na siminti carbide ne sau uku fiye da bakin karfe.

7. Ƙaƙƙarfan naƙasa da ƙwayar filastik na simintin carbide ƙananan ƙananan.

8. Mafi shahararren halayen simintin carbide shine babban taurinsa da tsayin daka. Lokacin amfani da tungsten carbide ya fi tsayi fiye da bakin karfe.

A halin yanzu, simintin carbides da ake amfani da su a cikin gyare-gyaren gida sun fi ƙunshi tungsten da cobalt.
