ʻO ke kila kila lapaʻau maʻemaʻe kiʻekiʻe 316LVM kūpono no nā mea lapaʻau a me nā mea hoʻokomo.

Ka Hoʻohui Kemika

ʻO ke ʻano kemika maʻamau o ke kila kila 316LVM:

• Chromium (Cr): 16.00-18.00%

•Nikala (Ni): 13.00-15.00%

•Molybdenum (Mo): 2.00-3.00%

•Manganese (Mn): ≤ 2.00%

•Silika (Si): ≤ 0.75%

•ʻO ka phosphorus (P): ≤ 0.025%

•Sulfur (S): ≤ 0.010%

•Kalapona (C): ≤ 0.030%

•Hao (Fe): Kaulike

Nā Waiwai Mekanika

ʻO ka maʻamau, loaʻa i ke kila kila 316LVM nā waiwai mechanical penei:

•Ikaika Tensile: ≥ 485 MPa (70 ksi)

•Ikaika Hua: ≥ 170 MPa (25 ksi)

•Elongation: ≥ 40%

•Paʻakikī: ≤ 95 HRB

Nā noi

Ma muli o kona maʻemaʻe kiʻekiʻe a me ka biocompatibility maikaʻi loa, hoʻohana nui ʻia ka 316LVM i:

•Nā mea hana ʻoki kino

•Nā mea hoʻokomo orthopedic

•Nā mea lapaʻau

•Nā mea hoʻokomo niho

•Nā alakaʻi pacemaker

Nā Pōmaikaʻi

•Ke Kū'ē ʻana i ka ʻAi ʻOle: ʻOi aku ka maikaʻi o ke kūpaʻa ʻana i ka ʻino o ka lua a me ka crevice, ʻoiai hoʻi i nā wahi chloride.

•Biocompatibility: Palekana no ka hoʻohana ʻana i nā implants lapaʻau a me nā mea hana e pili pono ana me nā ʻiʻo kanaka.

•Ikaika a me ka Ductility: Hoʻohui i ka ikaika kiʻekiʻe me ka ductility maikaʻi, e kūpono ai no ka hoʻokumu ʻana a me ka mīkini.

•Maʻemaʻe: Hoʻemi ke kaʻina hana hoʻoheheʻe vacuum i nā mea haumia a hōʻoia i kahi microstructure like.

Kaʻina Hana

He mea koʻikoʻi ke kaʻina hana hoʻoheheʻe hakahaka i ka hana ʻana i ke kila kila 316LVM. Pili kēia kaʻina hana i ka hoʻoheheʻe ʻana i ke kila i loko o kahi hakahaka e wehe i nā haumia a me nā kinoea, e hopena ana i kahi mea maʻemaʻe kiʻekiʻe. ʻO nā ʻanuʻu maʻamau:

1.Vacuum Induction Melting (VIM): Hoʻoheheʻe ʻia nā mea maka i loko o kahi vacuum e hōʻemi i ka haumia.

2.Vacuum Arc Remelting (VAR): Hoʻomaʻemaʻe hou i ka metala ma ka hoʻoheheʻe hou ʻana iā ia i loko o kahi vacuum e hoʻonui i ka homogeneity a hoʻopau i nā kīnā.

3. Hoʻokumu a me ka Mīkini: Ke hoʻoponopono ʻana i ke kila i nā ʻano i makemake ʻia, e like me nā kaola, nā pepa, a i ʻole nā ​​​​uea.

4.Lapaʻau Wela: Ke hoʻopili nei i nā kaʻina hana hoʻomehana a me ke anuanu i hoʻomalu ʻia e hoʻokō ai i nā waiwai mechanical a me ka microstructure i makemake ʻia.
