E hoʻohana i ka pā kila kūpaʻa

ʻO ka pā kila kūpaʻa ʻaʻahu i haku ʻia me ka pā hao hao haʻahaʻa a me ka ʻāpana pale ʻaʻahu.ʻO ka papa hana paʻa paʻa i ka alloy he 1 / 3 ~ 1 / 2 o ka nui o ka mānoanoa.I ka wā o ka hana, hāʻawi ka matrix i nā waiwai holoʻokoʻa e like me ka ikaika, ka paʻakikī a me ka plasticity e kūʻē i nā mana o waho, a ʻo ka ʻāpana paʻa paʻa paʻa e hāʻawi i nā waiwai pale e kūpono i nā koi o nā kūlana hana.

Hoʻopaʻa ʻia ka pā kila me ka hoʻopaʻa ʻana ma waena o ka ʻāpana pale a me ka substrate.Ma o nā lako hana kūikawā a me ke kaʻina hana hoʻoheheʻe ʻakomi, ua hoʻopaʻa ʻia ka paʻakikī paʻakikī paʻakikī paʻa ponoʻī i ka uwea hoʻoheheʻe ʻia ma ka substrate.ʻO ka helu o nā papa hana hoʻokahi a ʻelua a i ʻole nā ​​papa he nui.I ka wā o ke kaʻina hana, ʻike ʻia nā māwae transverse like ʻole ma muli o ka lākiō hoʻemi ʻokoʻa o ka alloy, ʻo ia ka hiʻohiʻona kupaianaha o ka pā kila pale.

Hoʻohui nui ʻia ka papa hana paʻa i ka chromium alloy, a ua hoʻohui pū ʻia nā ʻāpana ʻē aʻe e like me manganese, molybdenum, niobium a me nickel.Hoʻokaʻawale ʻia nā carbide i loko o ke ʻano metallographic i ke ʻano fiber, a pololei ke kuhikuhi o ka fiber i ka ʻili.Hiki i ka micro hardness o ka carbide ke piʻi ma luna o ka hv1700-2000 a hiki i ka paʻakikī o ka honua ke hiki i ka HRC58-62.Loaʻa ka paʻa paʻa o Alloy carbide i ka wela kiʻekiʻe, mālama i ka paʻakikī kiʻekiʻe, a loaʻa ka pale oxidation maikaʻi.Hiki ke hoʻohana maʻamau i loko o 500 ℃.

ʻO ke ʻano o ka ʻaʻahu ʻaʻahu i ke ʻano o ke kahawai haiki (2.5-3.5mm), ke kahawai ākea (8-12mm), ka pihi (s, w), etc.;Hoʻokumu nui ʻia ia me ka chromium alloy a me nā mea hoʻohui ʻē aʻe e like me manganese, molybdenum, niobium, nickel a me boron.Hoʻokaʻawale ʻia nā carbide i loko o ke ʻano metallographic i ke ʻano fiber, a pololei ke kuhikuhi o ka fiber i ka ʻili.ʻO ka maʻiʻo carbide he 40-60%, hiki i ka microhardness ke piʻi aku ma mua o ka hv1700, a hiki i ka paʻakikī o ka honua ke hiki i ka HRC58-62.

Ka laulā o ka noi

ʻO ka pā kila kūʻokoʻa he kiʻekiʻe ke kūpaʻa a me ka hopena maikaʻi.Hiki ke ʻoki, kūlou a welded.Hiki ke hoʻohui ʻia me nā hale ʻē aʻe e ka welding, plug welding a me ka pili bolt.He mea mālama manawa a maʻalahi i ke kaʻina o ka mālama.Hoʻohana nui ʻia ia i ka metallurgy, ka lanahu, ka sima, ka mana uila, ke aniani, ka mining, nā mea kūkulu hale, nā pōhaku lepo a me nā ʻoihana ʻē aʻe.Ke hoʻohālikelikeʻia me nā mea'ē aʻe, he hana koʻikoʻi koʻikoʻi, Ua makemake nuiʻia e nāʻoihana a me nā mea hana.
