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 lokulandela umkhondo wabathengi, 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.
