Kev phais mob Hlau ShowDown: 316L vs . 17-4 pH rau kev ua haujlwm immant

 

Vim li cas 316l nyiam tshaj 304 rau cov pob txha pob txha?
316L's ultra-low carbon (<=0.03%) prevents corrosion at welded joints in moist environments. Molybdenum (2.1-2.5%) enhances chloride resistance in bodily fluids. Nqus tau melting txo cov impurities rau<0.35 μg/cm²/week nickel ion release.

 

{17-4 p w frdict tau rov ua kom tsis muaj menyuam?
H900 Kev Kho Cua sov sov tau ua tiav 44 HRC Hardness Thaum Tswj Ductility Tsis kam (134 Degree}}}}

 

Cov alloys puas tuaj yeem ua rau MRI teeb meem?
316L: Tsis muaj zog paramagnetic (nyab xeeb rau 3T MT MRI) .
17-4PH: Ferromagnetic – may displace implants >7cm los ntawm scanner iSocener .

Lus teb: Siv 316L rau lub hlwb / txhappe immants nyob ze mri cov teb .

 

Dab tsi ua rau milant tsis ua tiav?
Fretting corrosion ntawm modular junctions {{0} Kev ntxhov siab ntawm thaj chaw muaj kev ntxhov siab hauv {}}% {}}

 

Kev cog hniav zoo li cas?
▫️ Grit-blasting: Tsim {3-5} μm roughness rau cov pob txha sib xyaw ua ke
▫️ Kev Hluav Taws Xob: Tshem tawm cov microbigrrts kom txo tau kev phom sij
▫️ HIS TXHEEJ: Hydroxyapatite txhawb nqa hluav taws xob
