Umgaqo weDayimane yeDayimani yokuphucula amandla okufakwa kwephakheji

1. Ukuveliswa kwedayimani edityanisiweyo ye-carbide

Umgaqo wokudibanisa umgubo wensimbi ngedayimani, ukufudumeza kubushushu obumiselweyo kunye nokufakwa ixesha elithile phantsi kwe-vacuum. Kula maqondo obushushu, uxinzelelo lwentsimbi lwanele ukugubungela, kwaye kwangaxeshanye, isinyithi sikhutshiwe kumgangatho wedayimani ukwenza idayimane edityanisiweyo.

2. Ukukhetha intsimbi edityanisiweyo

Ukwenzela ukuba idayimane iqinile kwaye ithembekile, kwaye iqonde ngakumbi impembelelo yokubekwa kwengqekembe kwi-COARD kwi-COARD, inyibilikiswe isinyithi esihlekisayo. Siyazi ukuba idayimane yi-Allomorphism ye-C, kwaye i-lattare yayo yi-tetrahedron eqhelekileyo, ngoko ke umgaqo wokudibanisa ubume besinyithi kukuba isinyithi sinobubele obulungileyo kwikhabhoni. Ngale ndlela, phantsi kweemeko ezithile, ukusebenzisana kwemichiza kwenzeka kwi-interwection, kusenziwa i-comicalbone yekhemikhali, kwaye i-membrane ye-Me-c. Ukungenelela kunye nethiyori ye-Adhesion kwinkqubo yentsimbi yedayimani ichaza ukuba intsasazo yemichiza yenzeka kuphela xa umsebenzi wobumbango we-Aw> 0 kwaye ufikelela kwixabiso elithile. Iqela elifutshane lexesha elifutshane lensimbi ye-AFET kwitafile yexesha, enjenge-cu, i-SN, AG, Zon. I-metrition yenguqu kwitafile ende, efana ne-TI, V, CR, MN Amandla amakhulu e-C.

3. Isibane sovavanyo

Kwiqondo lobushushu le-8500c, idayimani ayinakufikelela kumandla asimahla kwii-atom ze-carbon esebenzayo kunye ne-powder yedayimane yokwenza amandla e-carbide yentsimbi, kwaye ubuncinci i-9000c ukufezekisa amandla e-carbide yentsimbi. Nangona kunjalo, ukuba amaqondo obushushu aphezulu kakhulu, iya kuvelisa ilahleko evuthayo kwidayimane. Ukujonga impembelelo yempazamo yobushushu besilinganisa kunye nezinye izinto, amaqondo obushushu ovavanyo onamanzi amiselwe kwi-9500c. Njengoko kunokubonwa kubudlelwane phakathi kwexesha lokufakwa kunye nesantya sokuphendula (ngezantsi) ,? Emva kokufikelela kumandla asimahla esi sizukulwana sentsimbi sentsimbi, indlela yokuphendula iqhubeka ngokukhawuleza, kunye nesizukulwana sabadli, izinga lokuphendula liya kuncipha. Alithandabuzeki elokuba ngokulwandiswa kwexesha lokufakwa, ukuxinana kunye nomgangatho womaleko kuya kuphuculwa, kodwa emva kwemizuzu engama-60, umgangatho we-sueer akachaphazelekanga kangangeyure enye njengeyure enye; Ukuphakama kwe-vacuum, engcono, kodwa ilinganiselwe kwiimeko zovavanyo, sisebenzisa i-10ommhg.

Iphakheji ye-Intset I-Intset

Iziphumo zovavanyo zibonisa ukuba umzimba wesibeleko unamandla kwidayimani enamagqabi kunedayimane engacacanga. Isizathu sokubandakanywa kwesakhono sokufakelwa komzimba kwidayimani edityanisiweyo kukuba, ngokobuqu, kukho iziphene ezingaphezulu kunye nemicro-rocks kumphezulu okanye ngaphakathi kuyo nayiphi na idayimani engaphandle kwedayimane. Ngenxa yobukho bale microcract, amandla edayimani ayancipha, kwelinye icala, inqaku ledayimane alifane liphendule ngamacandelo omzimba wesibeleko. Ke ngoko, idiliya yediliya yedayimani engabhalwanga ingumsunguli wepakethi yoomatshini, kwaye olu hlobo lwephakheji lubuthathaka kakhulu. Nje ukuba umthwalo, ii-microcracks ezingentla ziya kukhokelela kuxinzelelo loxinzelelo, zikhokelela ekuhlakeni kwephakheji. Imeko yedayimane engaphezulu yahlukile, ngenxa yokubekwa kwefilimu yesinyithi, iziphene ezincinci zedayimani ziyagcwaliswa, kwelinye icala, kungekho nxalenye yedayinti enamachaphaza, akusekho uxinzelelo oluncinci. Okubaluleke ngakumbi, ukungenisa inyibilikisi kwi-nyibila kwi-soriy umzimba kuguqulwa ibe yikharbon kwidayimani kwidayimani yokungenisa idayisi. Isiphumo sensimbi yokuxhoma i-angle yedayimani isuka ngaphezulu kwe-100 o ukuya ngaphantsi kwe-500, iphucule kakhulu i-fayili yedayimani yedayimani yedayimani, i-dayini yedayili yedayisi, ke iphucula imizimba yediliya, ngaloo ndlela siphucule umzimba wesibeleko

Iphakheji yokubuyisa amandla. Kwangelo xesha, sikwakholelwa nokuba ezinye izinto ezinjengeeramitha ezithi, ubungakanani bedayimane, ibakala, ubungakanani bomzimba wesithambiso kwaye sinefuthe elithile kwi-Peage Proces. Ingcinezelo efanelekileyo ye-yenkunkuma inokunyusa ukuxinana ngoxinano kunye nokuphucula ubulukhuni bequmrhu elirhabaxa. Iqondo lobushushu elifanelekileyo lokushisa kunye nexesha lokufanisa linokukhuthaza iqondo lokuphendula lezikhephethi le-chimicaration kunye ne-ron edikwelweni kunye nenqanaba ledayimani lilingane, kwaye inqanaba elifanayo linyibilikisi.
