Ruitai Kitchen Knives: Babban Tushenku don Saitin Wuƙaƙen Kayan Wuka na Musamman daga China
Akwai nau'o'i biyu na hanyoyin shafa kayan aiki gama gari: haɓakar tururi na sinadarai (cvd) da ajiyar tururi ta jiki (pvd) a halin yanzu. A cikin 'yan shekarun nan, wasu sababbin matakai na sutura sun bayyana, wanda yana da kyakkyawan fata na aikace-aikacen.
CVD
CVD Hanyar, wanda nasa ne atomic jijjiga, ne mai Hanyar forming m Deposition Layer a saman dumama matrix ta yin amfani da tururi, hydrogen da sauran sinadaran aka gyara na karfe halide a high zafin jiki na 950 ~ 1050 ℃. Tsarin ya ƙunshi matakai guda uku: vaporization na abu, kai zuwa kusa da matrix da samuwar mai rufi akan matrix.
Daga cikin kowane nau'in hanyoyin cvd, vacuum ion bombardment da magnetron ion reaction spray ne aka fi amfani da su. cvd fasahar da aka yafi amfani da surface shafi na cimined carbide sabon kayan aikin, wanda ya dace da babban gudun roughing da Semi-kammala na matsakaici da nauyi sabon.
Idan aka kwatanta da sauran hanyoyin rufewa, hanyar cvd ba wai kawai tana da fa'idodin kayan aiki mai sauƙi ba, babban tsari, amma kuma yana da fa'idodi masu zuwa:
Akwai nau'i-nau'i iri-iri, waɗanda za'a iya shafa su da karafa, gami, carbides, nitrides, borides, oxides, carbon nitrides, oxygen nitrides, hydro-carbon nitrides, da sauransu: Tare da haɓaka mai girma da daidaituwa, ana iya samun suturar multilayer tare da kyallen takarda daban-daban, kuma kauri mai kauri yana da daidaituwa. Adadin ajiya yana da girma kuma mai sauƙin sarrafawa. Rubutun yana da tsabta mai tsabta da lafiya da hatsi mai yawa. Ƙarfin mannewa zai iya samun sutura mai kauri. Low tsari kudin, dace da taro samar.
PVD
Hanyar PVD ita ce cire kayan daga tushen da aka yi niyya ta nau'ikan jiki kamar evaporation ko sputtering, sa'an nan kuma saka waɗannan ions tururi mai kuzari a kan ƙasa ko ɓangaren ɓangaren don samar da Layer na fim ta hanyar sarari ko sarari. Halin tururi na atom ɗin ƙarfe da aka ƙafe ko sputtered yana kaiwa zuwa jibgewar mahadi da ake buƙata akan saman kayan aiki. pvd shafi za a iya mai rufi da titanium nitride, titanium carbon nitride, aluminum titanium nitrogen mahadi, kazalika da daban-daban refractory karafa na carbides da nitrides.
PVD fasahar da aka yafi amfani da surface jiyya na hadedde cimined carbide kayayyakin aiki da kuma high gudun kayan aiki karfe kayayyakin aiki. An yadu amfani da shafi jiyya na cimented carbide bit, milling abun yanka, reamer, famfo, musamman-dimbin yawa kayan aiki, waldi kayan aiki da sauransu.
MT-CVD
A tcn shafi tare da m fibrous crystalline ilimin halittar jiki za a iya samu ta matsakaicin zafin jiki sinadaran tururi shaida (MT-CVD) a 700 ~ 900 ℃. A shafi kauri iya isa 8 ~ 10μm, kuma zai iya zama a2o3, tin a kan surface Layer ta cvd fasaha.
MT-CVD shafi ruwa ya dace da babban gudun, high zafin jiki, babban kaya, bushe bushe yanayi, ta rayuwa ne game da sau biyu a matsayin high kamar yadda na talakawa shafi ruwa. Babban koma baya na cvd na hanyar shine cewa yawan zafin jiki na ajiya yana da girma, kuma kayan aikin annealing da nakasawa zai faru lokacin da kayan aikin ƙarfe mai ƙarfi ya kasance mai rufi. Don haka dole ne a kashe kayan aikin da aka ajiye.
