No ke aha i ʻoi aku ai ka maikaʻi o nā papa Chromium Carbide Overlay ma mua o ke kila maʻamau

ʻO ke kapa komo ʻana i hoʻokumu ʻia e nā ʻāpana mineral paʻakikī kekahi o nā ʻano hana hōʻino koʻikoʻi loa i nā ʻoihana kaumaha e like me ke kālai ʻana, ka sima, ka hana mana, a me ka metallurgy. I ka manawa hoʻokahi nā ʻāpana kūkulu e like menā ʻauwai, nā hoppers, nā papa wili, a me nā liner conveyor e ʻike i ka pau ʻana, emi iho ka pono o nā lako, piʻi aʻe nā kumukūʻai mālama, a kū mai nā pani i hoʻolālā ʻole ʻia.

No ka hōʻemi ʻana i kēia mau pilikia, ua lilo nā papa komo chromium carbide i mea hoʻonā maʻamau o ka ʻoihana, i mahalo ʻia no ko lākou paʻakikī kiʻekiʻe, ka hoʻopaʻa metallurgical ikaika, a me ke ola lawelawe lōʻihi. Eia nō naʻe, nui nā ʻokoʻa hana ma waena o nā mea hana. Hāʻawi kēia pepa i kahi loiloi metallurgical a me ka hoʻokolohua e wehewehe i ke kumu o WodonNā papa komo Chromium Carbide Overlay (CCO)hāʻawi i ke kūpaʻa ʻana o ka ʻaʻahu i hoʻohālikelike ʻia me nā kila ʻaʻahu maʻamau a me nā papa ʻaʻahu paʻakikī no ke kumu maʻamau.

ʻO ka hoʻohuihui kemika a me ke ʻano pae

ʻO ke kūpaʻa ʻana o ka ʻaʻahu o kahi papa ʻaʻahu composite e hoʻomalu nui ʻia e ka hoʻohui kemika o ka overlay a me ka microstructure hopena. Hana ʻia nā papa Wodon me nā pae kaulike o ke kalapona (C) a me ka chromium (Cr), e hōʻoia ana i ka nui o ka ua o nā carbides waiwai chromium i ka wā o ka solidification.

Ka Hoʻokumu ʻana o ka Carbide Phase - Hoʻopili ke kalapona me ka chromium e hana i nā carbides Cr₇C₃ hexagonal mua, e hōʻike ana i nā waiwai microhardness a hiki i ka HV1800, ʻoi aku ke kiʻekiʻe ma mua o ke kila kila.

Paʻakikī o Matrix - Hāʻawi ka papa kila akahai i ka paʻakikī a me ka omo ʻana i ka hopena, ʻoiai ʻo ka uhi e hōʻoiaʻiʻo i ka paʻakikī o ka ʻili. Hoʻopuka kēia ʻano papa pālua i kahi papa komo bimetallic me ka ikaika a me ke kūpaʻa.

Nā Hana Hoʻohālikelike a me nā Hoʻāʻo no nā Papa ʻAʻahu Bimetallic

ʻAʻole e like me nā kila kūkulu a i ʻole nā ​​​​kila paila, i hoʻomalu ʻia e nā kikoʻī honua i hoʻohui ʻia (e like me nā kūlana ASTM, EN, a i ʻole GB),nā papa komo bimetallicnele i kahi kūlana honua holoʻokoʻa i kēia manawa.

No kēia kumu, ʻo ke ʻano hana kūpono loa e hōʻoia i ka hana o ka ʻaʻahu ʻana, ʻo ia ka hoʻāʻo ʻana i ka huila laholio one maloʻo. Hoʻopili kēia hoʻāʻo maʻamau i ka ʻaʻahu ʻekolu-kino ma ke kaomi ʻana i kahi huila laholio e kūʻē i ka ʻili o ka ʻaʻahu ʻoiai e hānai ana i ke one silica maloʻo ma kahi wikiwiki i kāohi ʻia. Ma ka hoʻopaʻa ʻana i ka pohō nui o nā specimens, hiki ke helu ʻia ke kūpaʻa ʻaʻahu pili me ke ʻano kūʻokoʻa a me ke hana hou ʻana.

Nā kūlana hoʻāʻo:

Ke ʻano like o nā laʻana - Ua ʻoki ʻia nā laʻana mai Wodon, nā papa komo i lawe ʻia mai, a me nā papa kūloko i nā ana like.

Medium Abrasive - Ua hoʻohana ʻia ke one quartz angular e hoʻohālike i nā kūlana abrasive huhū loa.

Ukana a me ka Lōʻihi - Ua hoʻopili ʻia kahi ukana paʻa no 45 mau minuke ma lalo o nā wahi like.

Hoʻopau kēia ʻano hana i ka manaʻo geometric a i ʻole ka hana, e hōʻoiaʻiʻo ana e hōʻike wale ana ka hana ʻaʻahu i ana ʻia i nā ʻano mea o kēlā me kēia pā.

Nā Hualoaʻa Hoʻāʻo a me ka Nānā Hoʻohālikelike

Hoʻemi kaumaha ma hope o 45 mau minuke:

Papa ʻaʻahu Wodon: 0.148 g

Nā papa komo i lawe ʻia mai: 0.229 - 0.252 g

Nā pā lole home: 0.371 - 0.399 g

Ua hōʻoia kēia haʻawina ua ʻoi aku ka maikaʻi o nā papa komo chromium carbide i hana ʻia ma o nā kaʻina hana overlay holomua ma mua o nā kila maʻamau i nā wahi abrasive.
