Intsimbi yobushushu
Intsimbi engekho mthethweni ibhekisa kwintsimbi ekhethekileyo ye-alloy enozinzo oluhle lwamachiza kunye namandla aphezulu kubushushu obuphezulu, kwaye unokuziqhelanisa neemeko zobushushu obuphezulu. Isetyenziselwa ikakhulu ukwenziwa kwendawo yokufudumeza imizi-mveliso, i-injini yokudibana yangaphakathi, iPetroleum kunye noomatshini kunye nezixhobo kunye nezinye iindawo zobushushu obuphezulu.
(1) Umxholo wokumelana nobushushu
Ukumelana nobushushu bensimbi kubandakanya zombini uzinzo lwe-thermochemical kunye namandla amaqondo obushushu aphezulu.
Uzinzo lwe-thermochemical lubhekisa kubuchule bentsimbi ukuxhathisa ukuntywiliswa kweekhemidi zemithombo yeendaba ezahlukeneyo kwiqondo lomthombo eliphezulu, phakathi koko kubaluleke kakhulu kwaye okona kubaluleke kakhulu kukunganyangeki kwe-oxidation. Uzinzo lwe-thermochemical ikakhulu luzimisele ngokucokiseka kwezezikhewu zensimbi. Ukongeza i-CR, AL kunye no-SIC of CROCCDidant, ngenxa yokuba i-Antio, kuba i-CR, Al kunye ne-COCMACT kunye nokukhusela i-Oxygen xa i-oxid kubushushu obuphezulu2O3,A12O3mhlawumbi sio2Ifilimu. I-CR ye-cr yeyona nto ithandayo. Xa intsimbi yentsimbi 15%, ubushushu obushushu be-antioxidant yensimbi bunokufikelela kwinqanaba lama-900; Xa i-WCR 20% ~ 25%, Iqondo lokushisa le-antioxidant lentsimbi linokufikelela kwinqanaba le-1100. Umhlaba onqabileyo (isixa esincinci seYttrium, i-cirium, njl.njl.) Izinto zinokuphucula i-Oxidation yasebusuku. Oku ikakhulu kubangelwa kukuphuculwa kwentsebenzo ye-antioxxidant yefilimu yeside, kodwa inokuphucula amandla okubopha ifilimu yeside kunye nomphezulu wentsimbi. Kumphezulu we-Aluminum ye-Aluminum, i-Silicon okanye i-chromium aluminum, iChromium kunye ne-Silicon CO-I-CO-I-CO-I-CO-AYICE SICINGUMINGUSE.
Amaqondo obushushu aphezulu abhekisa kubuchule bentsimbi ukuze baxhathise iplastiki yeplastiki kunye nokuqhekeka kubushushu obuphezulu. Umda we-creep kunye namandla aqhubekayo asetyenziselwa ukuvavanya. Ngokongeza i-CR, NI, W, Mo nezinye izinto, ukomeleza iMatrix, ukuphucula ubushushu be-recrystallic kunye nokwandisa uzinzo lweMatrix; ukongeza v, ti, nb, i-NB, i-AL kunye nezinye izinto, ukwenza ubunzima obukhulu kunye nokuzinza kobushushu obufanelekileyo ,ntela ukukhula kwekhonkco kunye nokusasazwa; Khuphela u-B kunye nomhlaba onqabileyo (phi) kwaye uphucule amandla amaqondo obushushu aphezulu entsimbi.
