Ukubaluleka Kokugqoka i-Tungsten Carbide

Ukukhiqiza imikhiqizo ye-tungsten carbide, kufanele sithathe ukulungiselela izinto zokusetshenziswa kuqala, okuhlanganisa i-tungsten carbide powder kanye ne-binder powder. Khona-ke kufanele sizixube futhi sizigaye emshinini wokugaya ibhola, sizifafaze ku-sprayer esomile, futhi siwahlanganise abe yisimo nosayizi othile. Ngemuva kochungechunge lwezinqubo, kufanele siwacwilise esithandweni somlilo. Lokhu ukukhiqiza okuphelele ukuqinisa ukusebenza kwe-tungsten carbide. Sizokwenza lukhuni i-tungsten carbide ngokwelashwa okungaphezulu. Lesi sihloko sigxile ekufakeni i-tungsten carbide.

Ukukhiqiza i-tungsten carbide workpiece kudinga isikhathi eside. Ngesikhathi sokukhiqiza, sizogqoka i-tungsten carbide ukugwema i-oxidation ngaphansi kwamazinga okushisa aphezulu. I-tungsten carbide eboshwe inobulukhuni obuphakeme, ukumelana nokugqokwa, ukuzinza kwamakhemikhali, kanye nokungqubuzana okuncane kanye ne-thermal conductivity.

Ukufaka i-tungsten carbide kunezindlela ezimbili: eyodwa i-CVD, kanti enye i-PVD.

I-Chemical vapor deposition ibizwa nangokuthi i-CVD ngamafuphi. Umgomo wokufakwa komhwamuko wamakhemikhali ukusabela kwamakhemikhali okubangelwa ukushisa okushisayo endaweni yemikhiqizo eshisayo ye-tungsten carbide, nayo ethuthukiswayo ukuze ivumelane nezinto ezintsha kanye nemboni ye-semiconductor.

Ukufakwa komhwamuko obonakalayo kubuye kubizwe nge-PVD ngamafuphi, okuyindlela yokuhwashisa yokufaka ungqimba oluncane lwempahla emikhiqizweni ye-tungsten carbide. Ihlala inezinyathelo ezine, ukuhwamuka, ukuthutha, ukusabela, kanye ne-deposition. Le nqubo izokwenzeka ekamelweni le-vacuum futhi isebenzisa i-vacuum deposition ehlanzekile neyomile.

Ama-coatings anobulukhuni obuphezulu kakhulu kanye nokumelana nokugqoka. Uma kuqhathaniswa nemikhiqizo ye-tungsten carbide ngaphandle kwezingubo, imikhiqizo ye-tungsten carbide enezingubo zokugqoka ingasebenza ngesivinini esiphezulu sokusika, esingathuthukisa ukusebenza kahle kokukhiqiza. Ngaphezu kwalokho, lapho imikhiqizo ye-tungsten carbide ene-coatings kanye nangaphandle kwayo isebenza ngesivinini esifanayo sokusika, imikhiqizo ye-tungsten carbide enezingubo inokumelana nokugqoka okuphezulu.

Ezimweni eziningi, i-tungsten carbide idinga ukumbozwa, ikakhulukazi ukufaka i-tungsten carbide. Ukufakwa kwe-tungsten carbide kungathuthukisa ukumanzisa nobulukhuni futhi kuvikele i-tungsten carbide ekushiseni okuphezulu, i-oxidation, nokugqwala. I-coating ibalulekile ku-tungsten carbide.

Ngaphandle kokumboza, zikhona nezinye izindlela zokwenza i-tungsten carbide ibe lukhuni ngokwelashwa okungaphezulu, njengokuvela kwe-plasma, isifutho se-supersonic, ukushisela isivikelo segesi, ukuvala amalangabi, ukuvala i-vacuum, kanye nokuqina kokusabalalisa okushisayo.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
