Loaʻa i nā mea hana carbide i uhi ʻia nā pono penei:
(1) He paʻakikī loa ka mea uhi o ka papa ʻili a me ke kūpaʻa ʻana i ka ʻaʻahu. Ke hoʻohālikelike ʻia me ka carbide sima i uhi ʻole ʻia, ʻae ka carbide sima i uhi ʻia i ka hoʻohana ʻana i nā wikiwiki ʻoki kiʻekiʻe, no laila e hoʻomaikaʻi ai i ka pono hana, a i ʻole hiki ke hoʻonui nui i ke ola o ka mea hana ma ka wikiwiki ʻoki like.
(2) He liʻiliʻi ke koina o ka friction ma waena o ka mea i uhi ʻia a me ka mea i hana ʻia. Ke hoʻohālikelike ʻia me ka carbide sima i uhi ʻole ʻia, ua hoʻemi ʻia ka ikaika ʻoki o ka carbide sima i uhi ʻia i kekahi ʻano, a ʻoi aku ka maikaʻi o ka ʻili i hana ʻia.
(3) Ma muli o ka hana piha maikaʻi, ʻoi aku ka maikaʻi o ka versatility o ka pahi carbide i uhi ʻia a me ka laulā o ka noi. ʻO ke ʻano hana maʻamau i hoʻohana ʻia no ka uhi ʻana i ka carbide cemented ʻo ia ka hoʻokaʻawale ʻana i ka mahu kemika kiʻekiʻe (HTCVD). Hoʻohana ʻia ka plasma chemical vapor deposition (PCVD) e uhi i ka ʻili o ka carbide cemented.
Nā ʻano uhi o nā mea ʻoki wili carbide cemented:
ʻO nā mea uhi ʻekolu maʻamau ka titanium nitride (TiN), titanium carbonitride (TiCN) a me ka titanium aluminide (TiAIN).
Hiki i ka uhi ʻana o ka Titanium nitride ke hoʻonui i ka paʻakikī a me ke kūpaʻa o ka ʻili o ka mea hana, e hōʻemi i ke koina friction, e hōʻemi i ka hana ʻana o ka lihi i kūkulu ʻia, a hoʻolōʻihi i ke ola o ka mea hana. He kūpono nā mea hana i uhi ʻia me ka Titanium nitride no ka hana ʻana i ke kila haʻahaʻa a me ke kila kila.
He hina hina ka ʻili o ka uhi titanium carbonitride, ʻoi aku ka paʻakikī ma mua o ka uhi titanium nitride, a ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka ʻaʻahu. Ke hoʻohālikelike ʻia me ka uhi titanium nitride, hiki ke hana ʻia ka mea hana uhi titanium carbonitride ma ka wikiwiki hānai a me ka wikiwiki ʻoki (40% a me 60% ʻoi aku ka kiʻekiʻe ma mua o ka uhi titanium nitride, kēlā me kēia), a ʻoi aku ka kiʻekiʻe o ka wehe ʻana i nā mea hana. Hiki i nā mea hana i uhi ʻia me ka titanium carbonitride ke hana i nā ʻano mea hana like ʻole.
He hina a ʻeleʻele paha ka uhi titanium aluminide. Uhi nui ʻia ia ma luna o ka ʻili o ke kumu mea hana carbide i hoʻopaʻa ʻia. Hiki nō ke hana ʻia ke hiki ka mahana ʻoki i 800 ℃. He kūpono ia no ka ʻoki maloʻo wikiwiki. I ka wā ʻoki maloʻo, hiki ke wehe ʻia nā ʻāpana i loko o ka wahi ʻoki me ka ea i hoʻopaʻa ʻia. He kūpono ka Titanium aluminide no ka hana ʻana i nā mea palupalu e like me ke kila paʻakikī, ka titanium alloy, ka nickel-based alloy, ka hao hoʻolei a me ka silicon kiʻekiʻe alumini alloy.
Ka hoʻopili ʻana o ka ʻoki wili carbide cemented:
Ua ʻike ʻia hoʻi ka holomua o ka ʻenehana uhi mea hana i ka pono o ka nano-coating. ʻO ka uhi ʻana i nā haneli o nā papa o nā mea me ka mānoanoa o kekahi mau nanometer ma luna o ka mea kumu mea hana ua kapa ʻia ʻo nano-coating. He liʻiliʻi loa ka nui o kēlā me kēia ʻāpana o ka mea nano-coating, no laila ua lōʻihi loa ka palena o ka palaoa, nona ka paʻakikī wela kiʻekiʻe. , Ikaika a me ka paʻakikī haki.
Hiki i ka paʻakikī Vickers o ka nano-coating ke hōʻea i HV2800～3000, a ua hoʻomaikaʻi ʻia ke kūpaʻa ʻana o ka ʻaʻahu ma ka 5%～50% ma mua o nā mea micron. Wahi a nā hōʻike, i kēia manawa, ua hoʻomohala ʻia he 62 mau papa o nā mea hana uhi me nā uhi ʻokoʻa o ka titanium carbide a me ka titanium carbonitride a me 400 mau papa o nā mea hana nano-coated TiAlN-TiAlN/Al2O3.
Ke hoʻohālikelike ʻia me nā uhi paʻakikī i luna, ua kapa ʻia ʻo sulfide (MoS2, WS2) i uhi ʻia ma ke kila wikiwiki kiʻekiʻe he uhi palupalu, kahi i hoʻohana nui ʻia no ka ʻoki ʻana i nā mea hao alumini ikaika kiʻekiʻe, nā mea hao titanium a me kekahi mau metala kakaikahi.
Inā he mau pono kāu, e ʻoluʻolu e kelepona iā MSK, mālama mākou i ka hāʻawi ʻana i nā mea hana maʻamau i ka manawa pōkole a me nā hoʻolālā mea hana maʻamau no nā mea kūʻai aku.
