Ngwa

N'ihi ịdị ọcha ya dị elu yana ezigbo bioacompatibility, 316LVM na-ejikarị na:

•Ngwa ịwa ahụ

•Nkwụnye orthopedic

•Ngwa ahụike

•Ntinye eze

•Onye na-eme ihe ngwa ngwa na-eduga

Uru

•Nguzogide corrosion: Nguzogide dị elu na-egbochi pitting na corrosion crevice, ọkachasị na gburugburu chloride.

•Biocompatibility: Ọ dị mma maka ojiji na ntinye ọgwụ na ngwaọrụ ndị na-abanye na anụ ahụ mmadụ ozugbo.

•Ike na Ductility: Na-ejikọta ike dị elu na ezigbo ductility, na-eme ka ọ dị mma maka ịmepụta na machining.

•Ịdị ọcha: Usoro ịgbaze oghere na-ebelata adịghị ọcha ma na-eme ka microstructure dị otu.

Usoro mmepụta

Usoro ịgbaze oghere dị oke mkpa n'ịmepụta igwe anaghị agba nchara 316LVM. Usoro a gụnyere ịgbaze ígwè n'ime oghere iji wepụ ihe ndị na-adịghị ọcha na gas, na-eme ka ihe dị ọcha dị elu. Usoro ndị a na-agụnyekarị:
