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

Hoʻohui Kimia

ʻO ka hui kemika maʻamau o 316LVM stainless steel me:

• Chromium (Cr): 16.00-18.00%

•Nikela (Ni): 13.00-15.00%

•Molybdenum (Mo): 2.00-3.00%

•Manganese (Mn): ≤ 2.00%

•Silikino (Si): ≤ 0.75%

•ʻO Phosphorus (P): ≤ 0.025%

•Sulfur (S): ≤ 0.010%

•Kalapona (C): ≤ 0.030%

•Hao (Fe): Kaulike

Na Waiwai Mechanical

Loaʻa i ka 316LVM stainless steel nā waiwai mechanical penei:

•ʻOi aku ka ikaika: ≥ 485 MPa (70 ksi)

•Ka ikaika o ka hua: ≥ 170 MPa (25 ksi)

•Elongation: ≥ 40%

•Paʻakiki: ≤ 95 HRB

Nā noi

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

•Nā mea hana ʻokiʻoki

•Nā mea hoʻokomo orthopedic

•Nā mea lapaʻau

•Hoʻokomo niho

•Alakaʻi ʻo Pacemaker

Pono

•Kū'ē Kū'ē: Ke kū'ē maikaʻi loa i ka lua a me ka crevice corrosion, ʻoi aku hoʻi ma nā wahi chloride.

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

•Ka ikaika a me ka Ductility: Hoʻohui i ka ikaika kiʻekiʻe me ka ductility maikaʻi, kūpono ia no ka hana ʻana a me ka mīkini.

•Hoʻomaʻemaʻe: ʻO ke kaʻina hoʻoheheʻe ʻana i ka lepo e hōʻemi i nā haumia a hōʻoia i kahi microstructure like ʻole.

Kaʻina Hana Hana

He mea koʻikoʻi ke kaʻina hoʻoheheʻe vacuum i ka hana ʻana i ke kila kila 316LVM. ʻO kēia kaʻina hana i ka hoʻoheheʻe ʻana i ke kila i loko o kahi pahu e wehe ai i nā haumia a me nā kinoea, e loaʻa ai kahi mea maʻemaʻe kiʻekiʻe. Aia nā ʻanuʻu maʻamau:

1.Vacuum Induction Melting (VIM): E hoʻoheheʻe i nā mea maka i loko o kahi pahu e hoʻemi i ka haumia.

2.Vacuum Arc Remelting (VAR): E hoʻomaʻemaʻe hou i ka metala ma o ka hoʻoheheʻe ʻana i loko o kahi pahu e hoʻonui ai i ka homogeneity a hoʻopau i nā hemahema.

3.Forming and Machining: Hoʻopili i ke kila i nā ʻano i makemake ʻia, e like me nā kaola, nā lau, a i ʻole nā ​​uea.

4.Heat Treatment: Ke hoʻohana nei i nā kaʻina hana hoʻomehana a me ka hoʻomaha ʻana e hoʻokō i nā waiwai mechanical a me ka microstructure i makemake ʻia.
