Xa usiva Stellite 20, yintoni ethi qatha engqondweni? Kubantu abaninzi, kwanabanye kurhwebo, yenye nje into enzima okanye i-cobalt engagungqiyo. Bayidibanisa kunye ne-Stellite 6 okanye i-12. Kulapho kwenzeka khona impazamo yokuqala. Lirhamncwa elahlukileyo ngokupheleleyo. Eyam ingqikelelo kwangethuba yayikukuba ichromium yayo ephezulu kunye nomxholo we-tungsten yenze ukuba ibe yinguqulelo enzima yokuqhawuka kakhulu. Ithathe iintsilelo ezimbalwa zehlabathi lokwenyani ukuqonda i-niche yayo yokwenyani kulapho ufuna khona obo bunzima, ewe, kodwa kunye nomlo onzima ngokuchasene nohlobo oluthile lohlaselo olunokutya oluya kudla amanye amabanga ephila. Ayisosisombululo sendalo yonke, kwaye ukuyiphatha njengenye yindlela ekhawulezayo yokutshisa ibhajethi.
Ubume bezinto ezibonakalayo kunye nesizathu sokuba buqhathe abantu
Jonga ukubunjwa kwegama: malunga ne-50% yeCobalt, i-30% yeChromium, i-4.5% yeTungsten, i-1% yeCarbon. Kwiliso elingaqeqeshwanga, ifundeka njengefomula yeStellite yakudala. Umtyholi ukwibhalansi kunye nezinto ezincinci. Elo nqanaba le-Cr liphezulu kwisibhakabhaka kuthotho. Ityhala i-alloy kwindawo apho ukuziphatha kwayo kokudlula kwi-oxidizing acids itshintsha. Ndikhumbula iprojekthi yomkhono wempompo yeekhemikhali apho i-spec isanda kuthi i-cobalt alloy yokunxiba kunye nenkonzo yemichiza. Umyili uhambe nomgangatho ongaphezulu weStellite 6. Yahlala malunga neenyanga ezintathu ngaphambi kokuba i-pitting ibambe kwindawo ye-nitric acid. Uphononongo lwesidumbu lwasikhomba kulo Stellite 20. Undoqo yayingebobulukhuni nje; yayilaa maleko ashinyeneyo, anechromium-rich oxide eyenza kwaye ibambe phantsi kwezo meko.
Apha kulapho iitshati zokukhetha imathiriyeli eqhelekileyo zisilela khona. Baza kudwelisa iqela leengxubevange zokubola kunye nokunxiba, kodwa inxalenye ye-corrosion ayicacanga kakhulu. Ngaba i-sulfuric, i-hydrochloric, i-nitric, okanye i-slurry ene-chlorides? Stellite 20 ikhanya kwimidiya ye-oxidizing. Ekunciphiseni iiasidi? Hayi okuninzi. Kufuneka ulazi utshaba oluchanekileyo. Ndifunde oku ngolingo olunexabiso eliphezulu kunye neblade yomxube kwisityalo se-phosphoric acid. Imekobume yayineempawu zefluoride. Sisebenzise iStellite 20, kwaye ngelixa ixhathisa ukubola ngokubanzi ngcono kakhulu kunokwandulelayo, sabona amaxabiso okunxiba angalindelekanga. Iifluoride zaziwunciphisa lo mgangatho wokhuselo. Yayiluloyiso oluyinxenye kodwa yaqaqambisa imfuno yokucaciswa okugqithisileyo.
Olunye uqwalaselo oluqhelekileyo kubuchule balo ngendlela eyenziweyo, okanye kunoko, ukungabikho kwayo. Ihlala inikezelwa njengesamente okanye umgubo wokuwelda. Ukuba ucinga ukuba uya kufumana isitokhwe sebha kwaye uyijike njenge-316 engenasici, yilibale. Inethiwekhi ye-carbide ikhohlakele kwizixhobo.

Iinyani zeSicelo: iiMpumelelo kunye neeMisses ezikufutshane
Ndikhe ndayibona isebenza phi ngokuqinisekileyo? I-Valve trim kwinkonzo ye-nitric acid yincwadi yokufunda. Ayisiyiyo nje isihlalo, kodwa iziqu zeplagi kunye nezikhokelo apho uhlala unxibelelana ngokutyibilika kwindawo eshushu, ene-oxidizing. Umxhasi wayenemiba yokurhala okungapheliyo kunye ne-corrosion kunye neentsimbi ezikumgangatho ophezulu. Ukutshintshela kwi Stellite 20 nciphisa amaxesha okubaleka awandisiweyo ngomlinganiselo wesine. Kodwa ukufakela kwakubalulekile. I-substrate yayifanele ifudunyezwe ngaphambili, i-weld overlay ilawulwa ukuze igweme i-dilution kunye nokuqhekeka, kwaye emva koko umhlaba ugqityiwe. Yayingeyiyo into yokulahla; yayiyinkqubo yohlengahlengiso.
Olunye usetyenziso oluluqilima lukwiintlobo ezithile zemilomo yokutshiza ukwenzela udaka lwekhemikhali enobundlongondlongo. Indibaniselwano yefuthe lesantya esiphezulu sesuntswana kunye nokuvezwa kweekhemikhali kufuna lo mxube wepropati. Sasisebenzisa imilomo kwiplanti yokulungisa izimbiwa ephethe i-acidic, i-abrasive slurry. Imilomo ye-aluminiyam oxide yeceramic yangaphambili yayigqabhuka. I-Stellite 20 iphose imilomo yayinxibe ngokulinganayo kwaye iqikelelwa, ivumela ukucwangciswa kolondolozo endaweni yokuvalwa okungxamisekileyo. Iindleko beziphezulu ngaphambili, kodwa ixabiso lilonke lobunini lehla.
Ngoku malunga nokuphoswa. Umzi-mveliso wephepha wawufuna iblade kagqirha yokomisa umqulu, ojongene nobushushu obuphezulu kunye ne-acidic condensate. Banyanzelise iStellite 20 ngokusekwe kubushushu benkonzo ephezulu yephepha ledatha. Sasinamathandabuzo malunga nokudinwa kwe-thermal. Le blade yenziwe, yafakwa, yaza yasebenza kakuhle ekunxityweni kangangeenyanga ezisibhozo. Emva koko yaqhekeka, kungekhona ngenxa yokuguga, kodwa ngenxa yoxinzelelo lwebhayisikile eshushu. Sifunda ntoni? Stellite 20 inobunzima obushushu obulungileyo, kodwa ukuhanjiswa kwayo kwe-thermal kunye nokwandiswa kwe-coefficient ayingomlingo. Ngomothuko we-cyclic thermal, amanye amabanga e-cobalt okanye i-alloys esekwe kwi-nickel inokuba yinto engcono. Bekufanele ukuba sityhale umva ngakumbi kuphononongo lwesicelo.
Umqobo wokuCasa kunye noMachining
Olu ludonga olusebenzayo olubetha abaninzi. Ukufumana ukusasazwa kwesandi Stellite 20 Ukukhululeka kokushwabana kwe-porosity kunye neenyembezi ezishushu akuyonto encinci.
