Sirrin foda mai launin kore na silicon carbide don inganta aikin kayan haɗin gwiwa

Waɗanda suka yi aiki a cikin kayan haɗin gwiwa sun san cewa yana da wuya a haɗa fa'idodin kayan aiki daban-daban zuwa abinci mai kyau fiye da daidaita dangantakar da ke tsakanin suruka da suruka. Amma tun bayan bayyanarfoda mai launin kore na silicon carbide, "sihiri mai kayan ƙanshi", da'irar kayan haɗin kai ta kunna kai tsaye kan "yanayin buɗewa". A yau, bari mu buɗe wannan mayafin mai ban mamaki mu ga yadda wannan tarin foda kore zai iya sa manyan masu alfahari kamar su carbon fiber da yumbu su yi biyayya.

1. Jarumin "mai hazaka mai siffar murabba'i"

An haifi foda mai launin kore na silicon carbide a matsayin "foda ta mafarki" ta kayan haɗin. Taurin Mohs shine 9.5, wanda numfashinsa ya fi lu'u-lu'u muni. Wata masana'antar birki a Guangdong ta yi kwatancen. Kayan haɗin da aka haɗa da carbide mai launin kore na silicon 20% yana da ma'aunin juriyar lalacewa wanda ya ninka kayan gargajiya sau 3. Daraktan bitar Lao Huang ya taɓa samfurin ya yi gunaguni: "Da wannan tauri, ba za ku iya barin alama ba bayan goge shi da takarda mai yashi na rabin sa'a!"

Lantarkin zafin ya fi muni. Cibiyar Bincike ta Shandong ta auna bayanai kuma ta gano cewa ƙarfin wutar lantarki na kayan haɗin aluminum waɗanda ke ɗauke da 15% na silicon carbide kore ya tashi zuwa 220W/(m·K), wanda ya fi ƙarfin aluminum tsantsa da 30%. Ma'aikaci Xiao Liu ya kalli na'urar daukar hoton zafi ya yi ihu: "Wannan ingancin watsawar zafi yana kama da shigar da tsarin sanyaya ruwa akan CPU!"

Kwanciyar hankali a fannin sinadarai ya fi na musamman. A wani gwaji da aka yi kan kayan rufin bututun sinadarai a Ningbo, an jika kayan hade-haden silicon carbide kore a cikin sinadarin sulfuric acid mai yawa na tsawon rabin shekara, kuma yawan asarar nauyi bai kai kashi 0.3% ba. Mai duba inganci Lao Wang ya ɗaga samfurin ya yi alfahari da cewa: "Wannan juriyar tsatsa, har ma da tanderun alchemy na Taishang Laojun dole ne ya wuce sigari!"

2. "Lokacin sihiri" na tsarin haɗin gwiwa

Fasahar watsawa yanzu ta yi kyau sosai. Wani kamfani a Jiangsu ya ƙirƙiro haɗin "na'urar niƙa ta duban dan tayi + ƙwallon ƙwallo", wanda ke watsa ƙwayar micropowder daidai gwargwado fiye da lu'u-lu'u da ke cikin shayin madara. Jagora Lao Li ya ɗaga hoton na'urar hangen nesa ta lantarki ya yi alfahari da cewa: "Duba wannan yawan rarrabawa, tururuwa za su ɓace idan suka hau sama!"

Baƙar fasahar haɗakar hanyoyin sadarwa ta fi tsanani. Maganin haɗin nano da wani dakin gwaje-gwaje ya ƙirƙiro a Shanghai ya ƙara ƙarfin haɗin da ke tsakanin micropowder da matrix zuwa 150MPa. Shugaban aikin ya ɗaga gilashinsa ya ce: "Lokaci na ƙarshe da muka yi gwajin yankewa, kayan haɗin sun lalace, amma kayan haɗin bai wargaje ba!"

3. "Haskaka yanayin" gwajin yaƙi na gaske

Masana'antar sararin samaniya ta daɗe tana da hauka. Ana amfani da ruwan turbine na wani masana'antar injinan jiragen sama a Chengdu.kore silicon carbidedon ƙarfafa kayan haɗin da aka yi da yumbu, kuma juriyar zafin jiki kai tsaye har zuwa 1600℃. Direban gwaji Lao Zhang ya kalli allon jagora ya yi ajiyar zuciya: "Da wannan aikin, injinan jiragen sama dole ne su kira baba!"

Maƙallin batirin sabbin motocin makamashi ya fi ban sha'awa. Maƙallin haɗakar carbon fiber na wani masana'anta a Ningde yana da takamaiman ƙarfin ƙarfe sau 8 bayan an haɗa shi da carbide mai launin kore na silicon. A lokacin gwajin karo, injiniyan tsaro Lao Li ya taɓa ƙofar motar ya yi dariya: "Yanzu wannan jikin motar kamar sanye da riguna masu hana harsashi guda uku!"

Fannin na'urorin dumama zafi na tashar tushe ta 5G abin mamaki ne. Na'urar sanyaya zafi mai amfani da aluminum ta wani kamfanin kera ta Hangzhou tana da ma'aunin faɗaɗa zafi wanda aka sarrafa zuwa 4.8×10⁻⁶/℃. Daraktan fasaha ya nuna bayanan gwajin zagayowar zafi kuma ya yi alfahari da cewa: "Ana iya daidaita shi daga -50℃ zuwa 200℃, kuma canjin girman ya fi Virgo tsanani!"

4, "Tsawon lokaci" a cikin asusun farashi

Kada ka duba tsadar na'urarfoda mai siffar silicon carbide kore, tabbas yana da riba idan aka ƙididdige jimlar asusun. Wata masana'antar injina a Chongqing ta yi lissafin kuɗi: kodayake farashin kayan aiki ya ƙaru da kashi 25%, tsawon rayuwar kayan ya ninka sau huɗu, kuma kuɗin gyara da aka adana a cikin shekaru uku ya isa a gina sabon bita. Matar kuɗi ta danna kalkuleta ta yi dariya: "Wannan kasuwancin ya fi riba fiye da karɓar lamuni!"

Inganta ingancin samarwa ya fi farin ciki a ɓoye. A cewar ainihin ma'aunin layin samarwa mai sarrafa kansa a Tianjin, lokacin tsaftace kayan haɗin an rage shi da kashi 40%. Daraktan bitar ya kalli babban allon ya mari ƙafafunsa: "Yanzu ƙarfin samarwa kamar hawa roka ne, kuma abokan ciniki ba sa firgita lokacin da suke buƙatar yin oda!"

Micropowder na yau mai launin kore na silicon carbide ba ya zama samfurin ra'ayi a dakin gwaje-gwaje. Daga sararin samaniya mai shawagi a sararin samaniya zuwa sabbin motocin makamashi da ke gudana a ƙasa, daga guntun wayar hannu mai girman dabino zuwa ruwan injin turbine mai tsawon mita 100, yana ko'ina. Tsoffin masana'antar sun ce wannan abu ya yi rami a cikin rufin aiki na kayan haɗin gwiwa. A ganina, wannan ba kawai haɓakawa ne mai sauƙi ba, amma "harbi a hannu" ga masana'antar zamani. Idan wannan yanayin ya ci gaba, yana yiwuwa wata rana allunan yanke mu za su yi amfani da wannan fasahar baƙar fata - bayan haka, wa ba ya son kayan kicin ɗin su kasance daidai da kayan sararin samaniya?
