molybdenum zagaye sanda ga High-zazzabi sintering da zafi magani masana'antu
Maganin zafi na molybdenum yawanci ya ƙunshi matakai waɗanda ke haɓaka kayan aikin injin sa kamar ductility, tauri, da ƙarfi. Mafi yawan hanyoyin magance zafi na molybdenum sun haɗa da annealing da damuwa:
1. Annealing: Molybdenum yakan kasance anneal don rage taurinsa da kuma ƙara ductility. Tsarin shafewa yakan haɗa da dumama molybdenum zuwa takamaiman zafin jiki (yawanci kusan 1200-1400 ° C) sannan a sanyaya shi a hankali zuwa zafin jiki. Wannan tsari yana taimakawa rage damuwa na ciki da sake sake fasalin tsarin molybdenum, inganta ductility da taurin.
2. Rage damuwa: Sassan Molybdenum waɗanda suka yi aikin sanyi mai yawa ko machining ana iya samun sauƙin damuwa don rage damuwa na ciki da haɓaka kwanciyar hankali. Tsarin ya ƙunshi dumama molybdenum zuwa takamaiman zafin jiki (yawanci a kusa da 800-1100 ° C) da kuma riƙe shi a cikin zafin jiki na ɗan lokaci kafin a kwantar da shi a hankali. Taimakon damuwa yana taimakawa rage murdiya da rage haɗarin fashe abubuwan molybdenum.
Yana da mahimmanci a lura cewa ƙayyadaddun tsarin kula da zafi na molybdenum na iya bambanta dangane da abun da ke ciki na gami, aikace-aikacen da aka yi niyya da kaddarorin kayan da ake so. Sabili da haka, ana ba da shawarar tuntuɓar ƙwararrun kayan aiki ko koma zuwa ƙayyadaddun ƙa'idodin maganin zafi na molybdenum don tabbatar da ingantaccen magani don aikace-aikacen da aka bayar.
Rarraba molybdenum ya haɗa da aiwatar da ƙaddamar da foda na molybdenum da dumama shi zuwa zafin jiki a ƙasa da wurin narkewa, yana haifar da ƙwayoyin foda guda ɗaya don haɗawa tare. Wannan tsari yana haifar da samuwar ingantaccen tsarin molybdenum tare da ingantaccen ƙarfi da yawa.
Tsarin sintering yawanci ya haɗa da matakai masu zuwa:
1. Matsa foda: Yi amfani da mold ko mutu don danna molybdenum foda zuwa siffar da ake so. Tsarin ƙaddamarwa yana taimakawa samar da tsari mai daidaituwa a cikin foda.
2. Dumama: Faɗakarwar molybdenum foda yana zafi a cikin yanayi mai sarrafawa zuwa yanayin zafi a ƙasa da wurin narkewa na molybdenum. Wannan zafin jiki yawanci yana da girma don ɓangarorin foda guda ɗaya don haɗawa tare ta hanyar yaduwa, samar da ingantaccen tsari.
3. Densification: A lokacin aikin sintering, tsarin molybdenum yana ƙididdigewa azaman barbashi guda ɗaya suna haɗuwa tare. Wannan yana haifar da ƙarar yawa da ƙarfin sassan molybdenum sintered.
Ana amfani da Sintering sau da yawa don samar da kayan aikin molybdenum tare da siffofi masu rikitarwa da kuma buƙatun masu yawa, irin su abubuwa masu zafi, kayan wuta, jiragen ruwa, da dai sauransu. Tsarin yana samar da sassan molybdenum mai ƙarfi da ɗorewa tare da ingantattun kayan aikin injiniya wanda ya dace da aikace-aikacen zafi mai zafi.
