Si3N4 yumbu kwallaye

Silicon nitride yumbu kwallaye suna da ƙarfi mai ƙarfi, juriya mai ɗorewa, ƙarfin zafin jiki mai ƙarfi, juriya ta lalata, asid da haɓakar alkali, kuma za a iya amfani da su na dogon lokaci a cikin ruwan teku, kuma suna da kyawawan halayen rufi. Zai iya jimre wa amfani da rikitarwa da yanayin aiki.

Si3N4 yumbu kwallaye da babban tauri da nauyi nauyi. Lokacin amfani da su a cikin takamaiman kayan haɗi ko kayan aiki, suna da ƙaramin coefficient na gogayya da hanzari na nauyi, wanda ke haifar da rashin lalacewa da tsawaita rayuwar sabis ɗin kayan haɗi.

Si3N4 yumbu kwallaye suna da tsayayya ga yanayin zafi mai yawa kuma suna iya aiki tsayayye a cikin yanayin yanayin zafin ƙasa da ke ƙasa da digiri 1200 Celsius tare da ƙananan canje-canje masu girma. Ingantaccen aikin jijjiga na thermal, zafin faɗakarwar zafin jiki shine 900-1000 digiri Celsius.

Hakanan yana da kayan shafawa na shafa mai kuma ana iya amfani dashi a cikin mahallan da babu matsakaicin man shafawa mai ƙazantar. Zama kayan zabi don yumbu bearings da matasan yumbu ball bearings.

Idan aka kwatanta da ƙwallan ƙarfe, babban fa'idar kwallayen yumbu sune:

(1) Ya fi 59% haske fiye da ƙwallan ƙarfe, wanda ke rage ƙarfin tsakiya, mirgina da abrasion akan hanyar tsere lokacin da ɗaukar abu ke gudana cikin sauri;

(2) Yanayin elasticity ya fi na ƙarfe kashi 44%, wanda ke nufin cewa yawan lalacewa ya yi ƙasa da na ƙwallan ƙarfe lokacin da aka tilasta su;

(3) nessarfi ya fi ƙarfe, HRC ya kai 78;

(4) Coefficient na gogayya ne karami, ba magnetic, lantarki insulated, kuma mafi jure sinadaran lalata da karfe.

(5) Halin haɓakar haɓakar thermal shine 1/4 na ƙarfe, wanda zai iya tsayayya da canje-canje na zafin jiki kwatsam;

(6) finisharshen farfajiyar ya fi kyau, Ra na iya kaiwa 4-6 nanometers;

(7) Babban juriya mai zafin jiki, kwalin yumbu har yanzu yana da ƙarfi da ƙarfi a 1050 digiri Celsius;

(8) Ba zai yi tsatsa ba kuma zai iya aiki a ƙarƙashin yanayin shafawa mai-mai.
