Tungsten’s histori

Tungsten carbide ke thepa e kopantsoeng e nang le WC joalo ka karolo e thata le cobalt(Co) joalo ka karolo e kopanyang.Nalane ea setsi sena e ka saloa morao ho tloha 1700s. Ka nako eo, basebetsi ba merafong ba Lithabeng tsa Erz tse Saxony Jeremane ba ile ba hlokomela hore ore e meng e ne e tla kena-kenana le phokotso eacassiterite le ho hlahisa slag.But tungsten e ne e lee ntšitsoeng pele lejoeng wolframiteka Juan JoseD’Elhuyar le moen’ae Fausto. They e bilefeela fokotsa tungstic acid e sebelisa mashala ho etsa tšepe.Ka ho etsa joalo, ba fumane ka phoso hore ntlha e phahameng ka ho fetisisa ea ho qhibiliha ea ntho ena ke3422likhato Celsius----Tšepe e nang le ntlha e phahameng ka ho fetisisa ea ho qhibilihaho feta makhetlo a mabeli sebaka se qhibilihang sa polatinamo.Ka 1841, setsebi sa k'hemistri Robert Oxland o ile a fumana litokelo tsa patent tsa Brithani bakeng sa mekhoa ea tlhahiso ea sodium tungstate, tungstic acid, le metallic tungsten. Ena e bile tsoelo-pele e khōlō historing ea kajeno ea k'hemistri ea tungsten 'me e ile ea bula tsela bakeng sa tlhahiso ea indasteri ea tungsten.

Ka 1896, ho qaptjoa ka phoso ha tungsten carbide ho tlisitse liphetoho tsa phetoho indastering mme ho na le tšusumetso e kholo sechabeng sohle.It e ile ea sibolloa keHenri Moissanke mang eaMoputso oa Nobelr. Ho batla ho hlahisaan taemane ea maiketsetso, tsoekere e futhumetseng ea Moisson le tungsten oxide ka seboping. Tsoekere e ne e sebetsa e le ntho e fokotsang hore oxide e hlahisee tungsten carbide e qhibilihisitsoeng. E ne e bontša lintho tse ling tse lakatsehang, empa e ne e le brittle haholo hore e ka sebelisoa molemong ofe kapa ofe oa khoebo.Hho feta, Lebone la Osram le sebetsa Berlin WHOhlokomelazedbokhoni ba carbide haufinyane o ile a nka monyetla oa ho etsa samente ea tšepe, e nang le likaroloana tsa tungsten carbide tse kentsoeng ka har'a matrix ea cobalt. Carbide e ne e le thata ka mokhoa o makatsang hape e teteaneng ka makhetlo a mane ho feta titanium. The iindasteri e ile ea sebelisa motsoako oa tšepe kapele lits'ebetsong tsa eona tsa tlhahiso. 

In 1913, Khaellooflitaemane tsa indasteri Jeremane li etsa hore bafuputsi ba batle mokhoa o mong oa ho shoa ha daemane, o sebelisoang ho hula terata.

K'hamphani ea libonela-motlakase ea Jeremane e fana ka patent ea tungsten carbide kapa ka thata tšepe ka 1923. E entsoe ka "samente"haholotungsten e thatao lithollo tsa carbide (WC) ka har'a matrix a binder ea tšepe e thata ea cobalt ka mokelikeli oa mokelikeli. Sephetho se fetotse nalane ea tungsten: thepahorekopanya matla a phahameng, ho tiea, le boima bo phahameng.

Nakong ea lefatšeWWII, Majeremane ke bona ba pele ba ho sebelisa tungsten carbide core ka holimo-lebelo la lihlomo-ho phunya projectile. Litanka tsa Brithani li batla li "qhibiliha" ha li otloa ke li-projectiles tsena tsa tungsten carbide.

The1950s: Ho hlahisoa ha tšepe, nickel le cobalt superalloy ho qala ho tlatsa tlhoko ea thepa e ka mamellang mocheso o makatsang oa lienjine tsa jete.

1960-1990: Tungsten carbide kehaholothata,Taemane kentho e le 'ngoe ea tlhaho e ka e ngoaeang.

Nowadays tungsten carbide e atile haholo, mme ts'ebeliso ea eona e kenyelletsas ho seha tšepe, ho sebetsa ka mapolanka, ho kopanya metsoako, li-ceramics tse bonolo, tse se nang chips (ho chesa le ho bata), meepo, kaho, ho cheka majoe, likarolo tsa sebopeho, likarolo tsa moaparo le likarolo tsa sesole. Ho tloha ho extra-grippy cycling tiRes ho lisebelisoa tse nepahetseng tsa ho buoa, ho thata ho fumana sehlahisoa se tšoarellang se sa sebeliseng mofuta o itseng oa carbid.e.
