Fadada ion Alloy Kovar Wire Alloy-4J29

(Sunan gama gari: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 wanda aka fi sani da Kovar alloy. An ƙirƙiro shi ne don biyan buƙatar ingantaccen hatimin gilashi-zuwa-ƙarfe, wanda ake buƙata a cikin na'urorin lantarki kamar kwararan fitila, bututun injin, bututun hasken cathode, da kuma a cikin tsarin injin injin a cikin sinadarai da sauran binciken kimiyya. Yawancin ƙarfe ba za su iya rufewa da gilashi ba saboda yawan zafin su na exAN SIon ba iri ɗaya bane da gilashi, don haka yayin da haɗin ke sanyaya bayan an ƙera shi, damuwa saboda bambancin ƙimar exAN SIon na gilashi da ƙarfe yana sa haɗin ya fashe.

Kovar wani ƙarfe ne mai ƙarfe na nickel-cobalt wanda yayi kama da Fernico, wanda aka ƙera don ya dace da halayen thermal expAN SIon na gilashin borosilicate (~5 × 10?6 /K tsakanin 30 da 200 °C, zuwa ~10 × 10?6 /K a 800 °C) don ba da damar haɗin kai tsaye na injiniya a cikin yanayin zafi daban-daban. Yana samun aikace-aikace a cikin masu amfani da wutar lantarki waɗanda ke shiga cikin ambulan gilashin sassan lantarki kamar bututun injin (bawuloli), bututun X-ray da microwave da wasu kwararan fitila.
Ana amfani da sunan Kovar a matsayin kalma ta gabaɗaya don ƙarfen Fe-Ni tare da waɗannan takamaiman kaddarorin ƙarfen SIon na thermal expAN. Lura da takamaiman haɗin Fe-Ni wanda ke nuna ƙaramin ƙarfin ƙarfen SIon.

An ƙirƙiro Alloy-4J29 ne don biyan buƙatar ingantaccen hatimin gilashi-zuwa-ƙarfe, wanda ake buƙata a cikin na'urorin lantarki kamar kwararan fitila, bututun injin, bututun hasken cathode, da kuma a cikin tsarin injin injin a cikin sinadarai da sauran binciken kimiyya. Yawancin ƙarfe ba za su iya rufewa da gilashi ba saboda yawan zafin su na exAN SIon ba iri ɗaya bane da gilashi, don haka yayin da haɗin ke sanyaya bayan an ƙera shi, damuwa saboda bambancin ƙimar exAN SIon na gilashi da ƙarfe yana sa haɗin ya fashe.

Alloy-4J29 ba wai kawai yana da expand SIon mai zafi kamar gilashi ba, har ma ana iya yin lanƙwasa na thermal expand SIon ɗinsa wanda ba layi ba sau da yawa don daidaita gilashi, don haka yana ba da damar haɗin gwiwa ya jure yanayin zafi mai faɗi. A kimiyyance, yana haɗuwa da gilashi ta hanyar matsakaicin oxide Layer na nickel oxide da cobalt oxide; rabon ƙarfe oxide yana da ƙasa saboda raguwarsa da cobalt. Ƙarfin haɗin ya dogara sosai akan kauri da halayen oxide Layer. Kasancewar cobalt yana sa Layer oxide ya fi sauƙi ya narke kuma ya narke a cikin gilashin da aka narke. Launin toka, launin toka-shuɗi ko launin toka-kasa yana nuna kyakkyawan hatimi. Launin ƙarfe yana nuna rashin oxide, yayin da launin baƙi yana nuna ƙarfe da aka yi oxidized sosai, a duka biyun yana haifar da rauni a haɗin gwiwa.

Ana amfani da shi galibi a cikin kayan aikin injin tsabtace wutar lantarki da kuma sarrafa fitar da hayaki, bututun girgiza, bututun ƙonewa, magnetron na gilashi, TRAN SIstors, toshe hatimi, relay, jagorar da'irori masu haɗawa, chassis, maƙallan ƙarfe da sauran hatimin gidaje.
