Semiconductor usebenzisa i-accessory emnyama ye-alumina ye-ceramic ingalo

Semiconductor usebenzisa i-accessory emnyama alumina ingalo ceramic Umfanekiso ofakiweyo

Inkcazelo emfutshane:

Ukumelana nokunxiba kwe-alumina ceramics kuyafana ne-corundum, ukufikelela kwinqanaba lobulukhuni be-Mohs 9, kwaye ukunyanzeliswa kokugqoka kuthelekiswa ne-alloys superhard.Ukumelana nokushisa kwe-alumina ceramics kuneempawu ze-coefficient encinci yokwandisa i-thermal, amandla aphezulu omatshini kunye nokuhanjiswa kakuhle kwe-thermal.Kwangaxeshanye, i-alumina isetyenziswa ngokubanzi kwiindawo zoomatshini ezisetyenziswa phantsi kweemeko zobushushu obuphezulu ngenxa yokusebenza kwayo okuphezulu kobushushu obuphezulu (ukuya kuthi ga kwi-1700℃).

Iiseramikhi zealumina

1. Ubunzima obuphezulu

Ukuqina kwe-Rockwell yi-HRA80-90, ubunzima bungaphantsi kunedayimani, bungaphezulu kakhulu kunokumelana nokunxitywa kwentsimbi enganyangekiyo kunye nentsimbi engenasici.

2. Ukumelana nokunxiba okugqwesileyo

Ilinganiswe ngamaziko ophando oluchwephesha, ukumelana kwayo nokunxiba kufana namaxesha angama-266 entsimbi ye-manganese.I-Gaoming cast iron 171.5 amaxesha, ngokweminyaka yethu engaphezu kweshumi yophando lokulandelela abathengi, phantsi kweemeko ezifanayo zokusebenza, inokwandisa ubomi benkonzo yezixhobo ubuncinane amaxesha alishumi ngaphezulu.

3. Ubunzima obulula

Ubuninzi bayo be-3.5g / cm3 kuphela isiqingatha sentsimbi, enokunciphisa kakhulu umthwalo wezixhobo.
