what .are .the .5 .properties .of .cobalt-chromium .alloys .for .biomaterials? .- .correct
.answer.highly .resistive .to .corrosion, .resistant .to .fatigue .cracking, .relatively .ductile,
.exceptional .bio .compatibility, .high .strength.
what .is .the .reason .austenitic .stainless .steel .is .no .longer .used .for .metal-on-metal .pairs .in
.joints .such .as .the .hip? .- .correct .answer.the .wear .resistance .is .poor
Co-Cr .based .alloys .of .Stainless .Steel .have .been .associated .with .higher .degrees .of
._______ .due .to .their .strength .and .high .modulus. .- .correct .answer.stress-shielding
what .is .the .alloy .we .talked .about .under .the .stainless .steel .unit? .- .correct .answer.cobalt-
chromium .alloys
what .element .is .sometimes .put .in .cobalt-chromium .alloys .to .further .strengthen .them?
.what .is .the .downfall? .- .correct .answer.nickel, .some .people .are .allergic
