Ubhedu lwe-phosphorus, ekwabizwa ngokuba yi-phosphor bronze, tin bronze, tin phosphorus bronze. I-Bronze yenziwe nge-agent ye-degassing enomxholo we-phosphorus we-0.03-0.35%, umxholo we-tin we-5-8%, kunye nezinye izinto ezilandelwayo ezifana ne-iron Fe, i-zinc Zn, njl. Ine-ductility enhle kunye nokumelana nokukhathala, kwaye ingaba isetyenziswe kwizinto zombane kunye nezomatshini ezinokuthembeka okuphezulu kunemveliso yealloy yethusi ngokubanzi.
Ubhedu lwe-phosphorus, i-alloy ye-phosphorus kunye nobhedu. Faka esikhundleni i-phosphorus ecocekileyo yokunciphisa ubhedu kunye ne-alloys yobhedu, kwaye uyisebenzise njenge-phosphorus additive ekwenzeni i-phosphor bronze. Ikwahlulwe ibe ngamanqanaba ama-5%, i-10%, kunye ne-15% kwaye inokongezwa ngokuthe ngqo kwintsimbi etyhidiweyo. Umsebenzi wayo unamandla okunciphisa, kwaye i-phosphorus yenza ubhedu lube nzima. Kwanokongeza inani elincinci le-phosphorus kwi-copper okanye ubhedu kunokuphucula amandla ayo okukhathala.
Ukwenzaubhedu lwephosphor, kuyimfuneko ukucinezela ibhloko ye-phosphorus kwi-copper encibilikisiweyo kuze kube yilapho ukusabela kuyeka. Xa umlinganiselo we phosphorus kubhedu ungaphakathi kwe 8.27%, iyanyibilika kwaye yenze i-Cu3P, enendawo yokunyibilika engama-707 ℃. Indawo yokunyibilika kobhedu lwe phosphorus equlathe i 10% ye phosphorus yi 850 ℃, kwaye indawo yokunyibilika ye phosphorus yobhedu equlathe 15% ye phosphorus yi 1022 ℃. Xa idlula i-15%, i-alloy ayizinzile. Ubhedu lwephosphorus luthengiswa ngamaqhekeza okanye iigranules. EJamani, i-phosphorus zinc isetyenziswa endaweni yecopper ye-phosphorus ukonga ikopolo.
I-MetaIlophos ligama le-phosphozinc yaseJamani equlethe i-20-30% ye-phosphorus. Ubhedu lwentengiso oluncitshiswe nge-phosphorus, kunye nomxholo we-phosphorus ongaphantsi kwe-0.50%, ikwabizwa ngokuba yi-phosphor copper. Nangona i-conductivity yehla malunga ne-30%, ukuqina kunye namandla kwanda. Itoti ye-Phosphorus yingxubevange ye-tin kunye ne-phosphorus, esetyenziselwa ukunyibilikisa ubhedu ukuvelisa ubhedu lwe-phosphor. Itoti yePhosphorus idla ngokuqulatha ngaphezulu kwe 5% yephosphorus, kodwa ayinalothe. Inkangeleko yayo ifana ne-antimony, yikristale enkulu ekhanya ngokuqaqambileyo. Thengisa ngamashiti. Ngokwemigaqo ye-federal e-United States, kufuneka iqulethe i-3.5% ye-phosphorus kunye nokungcola okungaphantsi kwe-0.50%.
Iimpawu zobhedu lwe-phosphorus
Ibronzi ye-tin phosphorus inokumelana nokugqwala okuphezulu, ukumelana nokunxiba, kwaye ayivelisi iintlantsi ngexesha lempembelelo. Isetyenziselwa isantya esiphakathi kunye neebheringi ezisindayo, ezinobushushu obuphezulu bokusebenza obungama-250 ℃. Ixhotyiswe nge-othomathikhi ye-othomathikhi, inokusingatha izakhiwo zombane ezigobileyo ngaphandle koqhagamshelwano lwe-rivet okanye uqhagamshelwano lwe-friction, ukuqinisekisa uqhagamshelwano olulungileyo, u-elasticity olungileyo, kunye nokufakwa kunye nokususwa ngokutyibilikayo. Le ngxubevange ineepropathi ezigqwesileyo zokwenziwa koomatshini kunye neepropathi zokwenza itshiphu, ezinokucutha ngokukhawuleza ixesha lokwenziwa kweenxalenye.Ubhedu lwe-phosphorus, njenge-alloy ephakathi esetyenziselwa ukuphosa ubhedu, i-soldering kunye nezinye iindawo, ithatha indawo ebalulekileyo ekuphuhliseni uqoqosho lwelizwe.
