In this work, porous honeycomb lead zirconate titanate (PZT) ceramics with one dimensional ordered pore channels were fabricated by the ionotropic gelation of sodium alginate/PZT suspension SrCl2 solution, then piezoelectric cement/PZT paste different mass fraction PZT component cast into to produce cement-containing composites. The influences on microscopic morphology studied. relative permittivity (εr) and longitudinal strain coefficient (d33) composites measured predicted experiments...
In this study, we systematically examined the influence mechanisms of introduced cobalt coated alumina (Co-coated Al2O3) particles on microstructure and properties cobalt-chromium-molybdenum (CoCrMo) alloy printed by Laser Powder Bed Fusion (LPBF). The Co-coated Al2O3 composite powders with different density coating were prepared varying load from 1 g/150 mL to 2 during electroless plating process. Then they mixed CoCrMo in proportion wt.% formed standard samples LPBF technology. results...

In this work, 3-3 type porous lead zirconate titanate (PZT) ceramics were fabricated by incorporating particle-stabilized foams using the gel-casting method. Then, Portland cement pastes with different water/cement ratios (w/c) cast into to produce cement-based piezoelectric (PZT-PC) composites. The effects of w/c on phase structure, microscopic morphology, and electrical properties studied. results showed that amount hydrated products density PZT–PC composites increased increase from 0.3...
In this paper, the finite element method (FEM) and experiments were adopted to optimize processing parameters of selective laser melted cobalt-chromium (CoCr) alloys on basis volume energy density. According simulation results, both maximum temperature, heat-affected zone cooling rate molten pool increased with enhancement power scanning speed even under same By conducting relevant experiments, it is found that phase transformation, microstructure mechanical properties also influenced by...
As the largest joint of articular surface human body, hip was mainly composed femoral head and acetabulum, which a vital for activities thigh capacity bearing weight in requiring it to have good strength plasticity. In this study, Ni@Al2O3 with different particle sizes used as reinforcement phases. Additionally, influence alumina size on mechanical properties Ni@Al2O3-CoCrMo explored through tensile test.
As one of the joints with greatest load bearing capacity, hip joint requires high mechanical strength and plasticity. In this study, Ni-coated Al2O3 (Ni@Al2O3) particles different size (1μm, 10μm 30μm) were prepared by electroless plating employed to enhance properties SLM processed CoCrMo alloys. The morphology fracture section, friction experiment, tensile test all forming parts demonstrated that CoCrMo-Ni@30μmAl2O3 composites possessed best comprehensive properties. Due consistent...
