Loaʻa nā pono o nā mea hana carbide i uhi ʻia:
(1) He kiʻekiʻe kiʻekiʻe ka paʻakikī o ka mea uhi o ka papa honua a me ke kūpaʻa. Ke hoʻohālikelike ʻia me ka carbide cemented uncoated, hiki i ka carbide cemented coated i ka hoʻohana ʻana i nā wikiwiki ʻoki kiʻekiʻe, a laila e hoʻomaikaʻi ai i ka hana ʻana, a i ʻole hiki ke hoʻonui nui i ke ola mea hana ma ka wikiwiki ʻoki like.
(2) He liʻiliʻi ka coefficient o friction ma waena o ka mea i uhi ʻia a me ka mea i hana ʻia. Ke hoʻohālikelike ʻia me ka carbide cemented uncoated, ua hoʻemi ʻia ka ikaika o ka ʻoki ʻana o ka carbide cemented coated i kekahi ʻano, a ʻoi aku ka maikaʻi o ka maikaʻi o ka ʻili.
(3) Ma muli o ka hana piha maikaʻi, ʻoi aku ka maikaʻi o ka pahi carbide i uhi ʻia a ʻoi aku ka laulā o ka noi. ʻO ke ʻano hoʻohana maʻamau o ka uhi ʻana i ka carbide cemented he kiʻekiʻe wela chemical vapor deposition (HTCVD). Hoʻohana ʻia ʻo Plasma chemical vapor deposition (PCVD) e uhi i ka ʻili o ka carbide cemented.
ʻO ke ʻano o ka uhi ʻana i nā mea ʻoki wili carbide cemented:
ʻO nā mea uhi maʻamau ʻekolu he titanium nitride (TiN), titanium carbonitride (TiCN) a me titanium aluminide (TiAIN).
Hiki i ka Titanium nitride coating ke hoʻonui i ka paʻakikī a me ke kūpaʻa ʻana o ka ʻili o ka mea hana, e hoʻemi i ka coefficient friction, e hoʻemi i ka hana o ka lihi kūkulu ʻia, a hoʻonui i ke ola o ka mea hana. Pono nā mea hana i uhi ʻia ʻo Titanium nitride no ka hana ʻana i ke kila haʻahaʻa a me ke kila kila.
ʻO ka ʻili o ka titanium carbonitride coating he hina, ʻoi aku ka paʻakikī ma mua o ka titanium nitride coating, a ʻoi aku ka maikaʻi o ka pale ʻana. Ke hoʻohālikelike ʻia me ka titanium nitride coating, hiki ke hana ʻia ka mea paʻahana titanium carbonitride coating i ka wikiwiki hānai nui a me ka wikiwiki o ka ʻoki ʻana (40% a me 60% kiʻekiʻe ma mua o ka titanium nitride coating, kēlā me kēia), a ʻoi aku ka kiʻekiʻe o ka mea hana. Hiki i nā mea hana i uhi ʻia ʻo Titanium carbonitride i nā ʻano mea hana.
He hina a ʻeleʻele paha ka titanium aluminide coating. Hoʻopili nui ʻia ma ka ʻili o ke kumu hana carbide cemented. Hiki ke hana ʻia i ka wā e piʻi ai ka mahana ʻoki i 800 ℃. He kūpono no ka ʻoki maloʻo kiʻekiʻe. I ka wā o ka ʻoki maloʻo, hiki ke hoʻoneʻe ʻia nā ʻāpana o ka ʻokiʻoki me ka ea paʻa. He kūpono ka Titanium aluminide no ka hoʻoponopono ʻana i nā mea palupalu e like me ke kila paʻakikī, ka alloy titanium, ka nickel-based alloy, ka hao a me ke alumini alumini kiʻekiʻe.
No ka uhi ʻana o ka mea ʻoki wili carbide i hoʻopaʻa ʻia:
Hōʻike ʻia ka holomua o ka ʻenehana hoʻopili mea hana i ka pono o ka nano-coating. ʻO ka uhi ʻana i nā haneli haneli o nā mea me ka mānoanoa o kekahi mau nanometer ma luna o ka mea paahana i kapa ʻia he nano-coating. ʻO ka nui o kēlā me kēia'āpana o ka mea nano-coating mea liʻiliʻi loa, no laila ua lōʻihi loa ka palena o ka palaoa, a he kiʻekiʻe ka wela wela. , Ka ikaika a me ka paakiki ha'i.
Hiki i ka Vickers paʻakikī o ka nano-coating ke hiki i ka HV2800~3000, a ʻoi aku ka maikaʻi o ka pale ʻana i ka lole e 5% ~ 50% ma mua o nā mea micron. Wahi a nā hōʻike, i kēia manawa, ua hoʻomohala ʻia nā ʻāpana 62 o nā mea hana hoʻopili me nā ʻāpana ʻē aʻe o ka titanium carbide a me titanium carbonitride a me 400 mau papa o TiAlN-TiAlN/Al2O3 nano-coated mea hana.
Ke hoʻohālikelike ʻia me nā mea paʻa paʻa i luna, ʻo ka sulfide (MoS2, WS2) i uhi ʻia ma ke kila kiʻekiʻe i kapa ʻia he uhi palupalu, kahi i hoʻohana nui ʻia no ka ʻoki ʻana i nā alumini alumini ikaika kiʻekiʻe, nā alloys titanium a me kekahi mau metala laha.
Inā he pono kāu, e ʻoluʻolu e kelepona iā MSK, ʻoluʻolu mākou i ka hāʻawi ʻana i nā mea hana maʻamau i ka manawa pōkole a me ka hoʻolālā mea hana maʻamau no nā mea kūʻai aku.
