He aha ka Chromium Carbide Overlay Wear Plate a no ke aha i ʻoi aku ai kona kūpaʻa ma mua o ke kila maʻamau?

I nā ʻoihana kaumaha e like me ke kālai ʻana, ka sima, a me ka hana mana, he pilikia nui ka ʻino o nā lako. Hoʻopilikia pinepine nā ʻāpana kila maʻamau i ka ʻānai wikiwiki ʻana, e hopena ana i ka manawa pinepine e hoʻomaha ai a me nā hoʻoponopono pipiʻi. ʻO kēia kahi e hana aipā uhi uhi chromium carbidelilo ia i mea hoʻololi pāʻani. Akā he aha ka mea e ʻoi aku ai kona kūpaʻa i ke kapa komo ma mua o ke kila maʻamau?

Ke hoʻomaopopo nei i ka pā lole ʻana o ka Chromium Carbide Overlay

ʻO ka papa hana uhi chromium carbide he mea kūikawā i hoʻolālā ʻia e kūʻē i ka ʻaʻahu nui ʻana i nā wahi abrasive. Loaʻa iā ia kahi kumu kila haʻahaʻa kalapona i uhi ʻia me kahi papa paʻakikī i waiwai i nā ʻāpana chromium carbide, ʻo Cr₇C₃ ka mea nui. Hoʻokumu ʻia kēia mau carbides i ka wā o ke kaʻina hana kuʻi a ua hoʻolaha like ʻia ma luna o ka ʻili, e hāʻawi ana i ka palekana kūikawā mai ka paheʻe ʻana o ka ʻaʻahu, ka hopena, a me ka ʻino.

ʻAʻole e like me nā papa kila maʻamau, ka mea e hilinaʻi wale ana i ka paʻakikī o ka metala kumu, hoʻohana kēia mau papa i nā ʻāpana metala paʻakikī i hoʻokomo ʻia i loko o ka matrix, e hoʻolōʻihi nui ana i ke ola lawelawe.

No ke aha e ʻoi aku ai kona maikaʻi ma mua o ke kila maʻamau

1. ʻOi aku ka maikaʻi o ke ʻano Carbide

ʻO ke kī i ke kūpaʻa ʻana o ke kapa komo aia i ke ʻano a me ka hoʻolaha ʻana o nā carbides. Loaʻa i ke kila maʻamau nā carbides hao e like me Fe₃C, he palupalu a maʻalahi hoʻi ke kapa ʻia. I ka hoʻohālikelike ʻana, hana nā papa kapa komo chromium carbide i nā carbides chromium kiʻekiʻe e like me Cr₇C₃ - nā hui e hōʻike ana i nā pae paʻakikī o HRC 58–65.

He kūpaʻa maikaʻi loa kēia mau carbides a me ke kūpaʻa ʻana i ka abrasion, ʻoi aku hoʻi ma lalo o nā kūlana paheʻe maloʻo a i ʻole nā ​​​​​​kūlana wela kiʻekiʻe.

ʻIke Leʻaleʻa: ʻO ke kiʻekiʻe o ka lakio atomika o ka chromium i ke kalapona, ʻoi aku ka paʻa a me ka paʻakikī o nā carbides - kahi kumu nui i ka hana maikaʻi ʻana ma mua o ka papa kila kūpaʻa maʻamau.

2. Hoʻonohonoho liʻiliʻi i hoʻomaikaʻi ʻia

I loko o nā papa komo maikaʻi, hōʻike ka uhi paʻakikī i kahi matrix martensitic i hoʻopili ʻia me ka nui o nā carbides i hoʻolaha like ʻia. ʻAe kēia ʻano hui i ka papa e kūʻē i ka abrasion paheʻe a me ka hopena kaulike, e hoʻolilo ana iā ia i mea maʻalahi loa.

Eia nō naʻe, inā hana like ʻole nā ​​​​carbide - e like me nā ʻano like me ka ʻupena a i ʻole ma nā palena o ka palaoa - hiki ke emi koke ke kūpaʻa o ka ʻaʻahu. ʻO ia ke kumu he mea koʻikoʻi ka hana ʻana a me ka kaohi.

3. Kākoʻo paʻa no ka hoʻoheheʻe ʻana a me ka hana ʻana

ʻAʻole e like me nā keramika palupalu a i ʻole ke kila kila,nā papa komo i hui pū ʻiahōʻike i kahi kumu kila palupalu e hiki ai ke hoʻopili maʻalahi, kūlou, a ʻokiʻoki - me ka ʻoki plasma a me ka laser. Hiki i kēia i nā mea hana ke hana i nā ʻano paʻakikī e like me nā liner curved, nā ʻāpana komo, a me nā ʻāpana kūkulu no nā hoʻonohonoho maʻamau.

Nā Hoʻohana Honua Maoli: Ma hea e hoʻohana ʻia ai kēia mau papa?

Hoʻohana nui ʻia ka papa lole i uhi ʻia me ka chromium carbide i nā ʻāpana kahi i ʻike nui ʻia ai ke ʻano o ka lole i kēlā me kēia lā:

ʻEli ʻana: Nā ʻauwai hoʻoili, nā hoppers,nā papa pale

Nā hale hana sima: Nā cone hoʻokaʻawale, nā mea hānai clinker, nā mea hoʻoili wili

Nā hale hana mana wela: Nā laina wili lanahu, nā ʻōnaehana lawelawe lehu

Nā wili kila: Nā hale hana sinter, nā ʻōpala mea,nā ʻauwai hoʻokuʻu

I kēlā me kēia hihia, ʻo ka hoʻololi ʻana i nā ʻāpana maʻamau me kahi pā lole chromium kiʻekiʻe e hoʻolōʻihi nui i ke ola a hoʻemi i ka mālama i hoʻonohonoho ʻole ʻia.

Ke koho ʻana i ka pā lole kūpono

I ke koho ʻana i kahi pā uhi chromium carbide, e noʻonoʻo i kēia mau mea:

Ka mānoanoa a me ka haku mele ʻana o ka uhi (e laʻa, 4+4mm, 6+6mm, 8+6mm)

ʻO ka hapa nui o ka Carbide (makemake ʻia ʻo 30%+)

Kaʻina hana kuʻihao (ʻāʻī i hoʻoluʻu ʻia vs. ʻāʻī hāmama)

Nā koi ʻoki (plasma, laser)

Eia kekahi, e hōʻoia mau inā kū ka huahana i nā pae hoʻohālikelike maikaʻi e like me ke kūlike o ka paʻakikī, ke ʻano metallographic, a me ke kūpaʻa i ka hopena.
