Amanqaku aphambili kunye nembali yosetyenziso lwe-ferroboron(FeB)

I-Ferroboron yintsimbi yentsimbi eyenziwe nge-boron kunye nentsimbi, esetyenziswa kakhulu kwintsimbi kunye nentsimbi.Ukongeza i-0.07% B kwintsimbi inokuphucula kakhulu ukuqina kwentsimbi.I-Boron yongezwe kwi-18% Cr, 8% Ni intsimbi engatyiwa emva konyango inokwenza imvula ibe lukhuni, iphucule amandla obushushu obuphezulu kunye nobulukhuni.I-Boron kwintsimbi etyhidiweyo iya kuchaphazela i-graphitization, ngaloo ndlela inyusa ubunzulu bomngxuma omhlophe ukwenza kube nzima kunye nokunxiba ukuxhathisa.Ukongeza i-0.001% ~ 0.005% ye-boron kwintsimbi ekhatywayo edibeneyo iluncedo ekwenzeni inki ye-spheroidal kunye nokuphucula ukuhanjiswa kwayo.Okwangoku, i-aluminiyam ephantsi kunye ne-carbon iron boron ephantsi zezona zixhobo ziphambili ze-amorphous alloys.Ngokomgangatho we-GB5082-87, i-boron ye-iron yaseChina ihlulwe ibe yikhabhoni ephantsi kunye nekhabhoni ephakathi iindidi ezimbini zamabakala esi-8.I-Ferroboron yi-alloy ye-multicomponent eyenziwe ngentsimbi, i-boron, i-silicon kunye ne-aluminium.
I-Ferric boron yi-deoxidizer eyomeleleyo kunye ne-agent yokongeza i-boron ekwenzeni intsimbi.Indima ye-boron kwintsimbi kukuphucula ngokubonakalayo ukuqina kunye nokubuyisela inani elikhulu lezinto ezixutywayo kunye nexabiso elincinci le-boron, kwaye inokuphucula iimpawu zoomatshini, iipropati zokuguqulwa okubandayo, iipropati ze-welding kunye neempawu zokushisa okuphezulu.
Ngokomxholo wekhabhoni we-boron iron unokwahlulwa kwibakala eliphantsi lekhabhoni kunye nenqanaba lekhabhoni eliphakathi kwiindidi ezimbini, ngokulandelanayo kumabakala ahlukeneyo entsimbi.Ukwakhiwa kweekhemikhali ze-ferric boron zidweliswe kwiThebhile 5-30.I-carbon iron boride ephantsi iveliswa yindlela ye-thermit kwaye inomxholo ophezulu we-aluminium.I-carbon boron iron ephakathi iveliswa yinkqubo ye-silicothermic, enomxholo ophantsi we-aluminium kunye nomxholo ophezulu wekhabhoni.Oku kulandelayo kuya kwazisa iingongoma eziphambili kunye nembali yokusetyenziswa kwe-iron boron.
Okokuqala, iingongoma eziphambili zokusetyenziswa kwe-iron boron
Xa usebenzisa i-iron boride, la manqaku alandelayo kufuneka aqatshelwe:
1. Isixa se-boron kwi-iron boron ayifani, kwaye umehluko mkhulu kakhulu.Iqhezu lobunzima beboron elinikwe kuluhlu olusemgangathweni ukusuka kwi-2% ukuya kwi-6%.Ukuze ulawule ngokuchanekileyo umxholo we-boron, kufuneka uhlanjululwe kwisithando somlilo se-vacuum induction ngaphambi kokusetyenziswa, kwaye emva koko usetyenziswe emva kokuhlalutya;
2. Khetha ibakala elifanelekileyo le-iron boride ngokwentsimbi yokunyibilikisa.Xa kunyibilikiswa intsimbi ye-boron ephezulu kwizityalo zamandla enyukliya, kufuneka kukhethwe i-carbon ephantsi, i-aluminiyam ephantsi, i-phosphorus yentsimbi ephantsi.Xa kunyibilikiswa i-boron equlethe i-alloy structural iron, i-medium carbon grade iron boride inokukhethwa;
3. Izinga lokubuyisela i-boron kwi-iron boride yehla ngokunyuka komxholo we-boron.Ukuze ufumane isantya esingcono sokubuyisela, kunenzuzo ngakumbi ukukhetha i-iron boride kunye nomxholo ophantsi we-boron.
Okwesibini, imbali ye-iron boron
UDavid waseBrithani (H.Davy) okokuqala ngqa ukuvelisa i-boron nge-electrolysis.I-H.Moissan yavelisa i-carbon iron borate ephezulu kwiziko lombane le-arc ngo-1893. Ngeminyaka yoo-1920 kwakukho amalungelo awodwa omenzi wechiza okwenziwa kwe-iron boride.Ukuphuhliswa kweealloyi ze-amorphous kunye nezixhobo zemagnethi ezisisigxina kwi-1970s zandisa imfuno ye-iron boride.Ekupheleni kweminyaka yoo-1950, i-Beijing Iron kunye ne-Steel Research Institute yase-China yaphuhlisa ngempumelelo i-iron boride ngendlela ye-thermit.Emva koko, uJilin, uJinzhou, uLiaoyang kunye nezinye imveliso yobuninzi, emva kwe-1966, ngokukodwa yimveliso yeLiaoyang.Kwi-1973, i-iron boron yaveliswa sisithando sombane e-Liaoyang.Ngowe-1989, intsimbi ephantsi ye-aluminium-boron yaphuhliswa yindlela yesithando somlilo sombane.
