ʻO nā ʻano uhi kumu o ka wili hope

ʻIke ʻia ʻo ka mill hope carbide he mill hope carbide cemented. ʻO ka paʻakikī o ka mea hana pono'ī ma waena o HRA88-96 degere. Akā me ka uhi ʻana ma ka ʻili, hiki mai ka ʻokoʻa. ʻO ke ala liʻiliʻi loa e hoʻomaikaʻi ai i ka hana o kahi wili hope e hoʻohui i ka uhi kūpono. Hiki iā ia ke hoʻonui i ke ola o ka mea hana a me ka hana.

He aha nā uhi kumu o ka wili hope ma ka mākeke?

1.TiN - Titanium Nitride - ka uhi pale ku'e no ke kumu nui

ʻO TiN ka ʻaʻahu maʻamau a me ka pale ʻana i ka abrasion. Hoʻemi ia i ka friction, hoʻonui i ka paʻa kemika a me ka mahana a hoʻemi i ka pipili ʻana o nā mea i hana pinepine ʻia i ka wā e hana ana i nā kila palupalu. He kūpono ʻo TiN no ka uhi ʻana i nā mea hana i hana ʻia me nā carbides i hoʻopaʻa ʻia - nā pahu drill, nā mea ʻoki wili, nā mea hoʻokomo mea hana ʻoki, nā kī, nā reamers, nā pahi kuʻi, nā mea ʻoki ʻoki, nā mea ʻoki a me nā flexion, matrices, forms, etc. No ka mea he biocompatible, hiki iā ia. e hoʻohana ʻia ma nā mea lapaʻau (nā ʻoki a me nā niho) a me nā mea implantable. Ma muli o kona leo kala gula, ua ʻike ʻo TiN i ka hoʻohana ākea ma ke ʻano he uhi hoʻonaninani. Hoʻopau maʻalahi ka uhi ʻia ʻo TiN mai nā kila mea hana. Hiki i ka hoʻoponopono hou ʻana i nā mea hana ke hoʻemi nui i nā kumukūʻai ʻoi aku ka nui o ka hoʻohana ʻana i nā mea hana makamae.

2.TiCN - Titanium Carbo-Nitride - e hoʻohana i ka uhi kūpaʻa kū'ē i ka ʻino

ʻO ka TiCN kahi mea hoʻopili maikaʻi loa. ʻOi aku ka paʻakikī a ʻoi aku ka paʻakikī o TiCN ma mua o TiN. Hiki ke hoʻohana ʻia no ka ʻaʻahu ʻana i nā mea hana ʻokiʻoki, ke kuʻi ʻana a me ka hana ʻana i nā mea hana, nā ʻāpana mold injection a me nā mea lole ʻē aʻe. No ka mea biocompatible, hiki ke hoʻohana ʻia ma nā mea lapaʻau a me nā mea implantable. Hiki ke hoʻonui ʻia ka wikiwiki o ka mīkini a hiki ke hoʻonui ʻia ke ola o ka mea hana e like me 8x i ka hilinaʻi ʻana i ka noi, coolant a me nā kūlana machining ʻē aʻe. Manaʻo ʻia ka uhi ʻana o TiCN e hoʻohana no ka ʻoki ʻana i ka maʻalili ma muli o kona kūpaʻa haʻahaʻa haʻahaʻa. Hoʻopau maʻalahi ka uhi ʻana o TiCN i hoʻohana ʻia a hoʻihoʻi hou ʻia ka mea hana. Hiki i ka hoʻoponopono hou ʻana i nā mea hana makamae ke hoʻemi nui i nā kumukūʻai.

3. ʻO ka ʻili aluminika-titanium-nitride (AlTiN)

He hui kemika ia o nā ʻeleu ʻekolu, aluminika, titanium, a me ka nitrogen. Aia ka mānoanoa o ka uhi ma waena o 1-4 micrometers (μm).

ʻO ka hiʻohiʻona kūikawā o ka uhi ʻana o AlTiN ʻo ia ke kūpaʻa kiʻekiʻe loa i ka wela a me ka oxidation. ʻO kēia kekahi ma muli o ka paʻakikī nano o 38 Gigapascal (GPa). ʻO ka hopena, ʻo ia ka mea e paʻa mau ana ka ʻōnaehana uhi ʻoiai ʻoi aku ka wikiwiki o ka ʻoki ʻana a me ka mahana ʻoki kiʻekiʻe. Hoʻohālikelike ʻia me nā mea hana ʻole, ka uhi ʻana o AlTiN, ma muli o ka noi, e hoʻonui i ke ola lawelawe a hiki i ʻumikumamāhā.

Ua kūpono loa ka uhi ʻana i loko o ka alumini no nā mea paahana pololei, e ʻoki i nā mea paʻakikī e like me ka laʻana. kila (N/mm²)

ʻO ka wela o ka hoʻohana ʻana he 900° Celcius (ma kahi o 1,650° Fahrenheit) a ua hoʻohālikelike ʻia me ka uhi ʻana o TiN he 300° Celcius ke kū kūʻē i ka wela.

ʻAʻole koi ʻia ka hoʻoluʻu. Ma ka laulā, hoʻonui naʻe ka hoʻoluʻu i ke ola lawelawe o ka mea hana.

E like me ka mea i ʻōlelo ʻia ma TiAlN coating ma keʻano laulā, pono e hoʻomaopopo ʻia ʻo ka uhi ʻana a me ke kila mea hana pono ke kūpono no ka hoʻohana ʻana i nā mea paʻakikī. ʻO ia ke kumu i uhi ai mākou i nā drill kūikawā i hana ʻia me ka tungsten-carbide me AlTiN.

4.TiAlN - Titanium Aluminum Nitride - hoʻokomo i ka pale pale no ka ʻoki wikiwiki

ʻO TiAlN kahi uhi me ka paʻakikī maikaʻi loa a me ke kūpaʻa wela a me ka oxidation. ʻO ka hoʻohui ʻia ʻana o ka alumini ka mea i hoʻonui ai i ke kūpaʻa wela o kēia uhi PVD composite e pili ana i ka uhi TiN maʻamau e 100°C. Hoʻopili pinepine ʻia ʻo TiAlN i nā mea hana ʻoki wikiwiki i hoʻohana ʻia ma nā mīkini CNC no ka mīkini ʻana i nā mea ʻoi aku ka ʻoi aku ka paʻakikī a me nā kūlana ʻoki koʻikoʻi. He kūpono ʻo TiAlN no nā mea ʻoki wili metala paʻakikī monolithic, nā ʻāpana drill, nā mea hoʻokomo mea hana ʻoki a me nā pahi hana. Hiki ke hoʻohana ʻia i nā noi mīkini maloʻo a kokoke paha maloʻo.
