Microstructure， electrochemical， wear and corrosive wear performance of laser-based powder bed fusion(lpbf) and wrought biomedical Ti-6Al-4V alloys

Transactions of Nonferrous Metals society of China 2024年

Wrought and laser powder bed fusion （LPbF） Ti-6Al-4V specimens were comparatively evaluated， with the objective to determine LPbF Ti-6-4’s suitability for biomedical applications. Testing included nanoindentation， cyclic polarization in simulated body fluid （sbF， 37 ℃ ）， and dry and sbF “ball-on-Plate” sliding. Wrought Ti-6-4 exhibited a lamellar （α+β） microstructure， whereas LPbF displayed a fine-grained α'-martensite microstructure. LPbF Ti-6-4 demonstrated ～3% higher indentation modulus and ～32% higher hardness， while wrought Ti-6-4 showed ～8% higher plasticity. both alloys exhibited low corrosion rates (10–5mA/cm2order) and true passivity (10–4mA/cm2order). No localized corrosion was observed in either alloy， except for occasional metastable pitting in the LPbF alloy. However， LPbF Ti-6-4 presented higher corrosion rate and passive current， ascribed to its martensitic structure. During dry sliding， LPbF Ti-6-4 exhibited ～14% lower volume loss compared to wrought Ti-6-4. sliding in sbF increased volume losses for both alloys， with wear resistances nearly equalized， as the advantage of LPbF Ti-6-4 decreased due to more intensive wear-accelerated corrosion induced by the stressed martensite. Overall， the results demonstrate the suitability of LPbF Ti-6Al-4V for biomedical uses.

The complete and incomplete fusion cross sections for ^(6)Li+^(209)bi were measured using the in-beamγ-ray method around the Coulomb *** cross sections of(deuteron captured)incomplete fusion(iCF)products were re-quantified experimentally for this reaction *** results reveal that the iCF cross section is equivalent to that of complete fusion(CF)above the Coulomb barrier and dominant near or below the Coulomb barrier.A theoretical calculation based on the continuum discretized coupled channel(CDCC)method was performed for the aforementioned CF and iCF cross sections;the result is consistent with the *** universal fusion function(UFF)was also compared with the measured CF cross section for different barrier parameters,demonstrating that the CF suppression factor is significantly influenced by the choice of potential,which can reflect both dynamic and static effects of breakup on the fusion process.
