Post-treatment is crucial to improve the comprehensive performance of laser-cladded martensitic stainless steel coatings. In this work, a low-temperature tempering treatment (210 °C), for first time, was performed on AISI 420 coating. The microstructure and properties pre- post-tempering specimens were carefully investigated by XRD, SEM, TEM, micro-hardness tester, universal material testing machine an electrochemical workstation. results show that as-cladded coating mainly consisted...
Martensitic stainless steel (MSS) coatings with different vanadium (V) contents (0–1.0 wt%) by microalloying have been successfully fabricated utilizing a unique laser cladding technique. The microstructure and properties of the resulting MSS coatings, without element V addition, carefully investigated various advanced techniques, including XRD, SEM, TEM, microhardness tester, universal material testing machine, electrochemical workstation. It was found that V-free coating mainly composed...
The corrosion protection of Hastelloy-N alloy in LiF-NaF-KF (commonly referred to as FLiNaK) molten salt has been developed by pure Ni and Co coatings using the laser cladding technique. An immersion experiment with samples was performed FLiNaK at 900 °C for 100 h. It found that rates Ni-coated specimen Co-coated are 39.9% 35.7% alloy, respectively. A careful microstructural characterization indicates a selective dissolution elemental Cr occurred surface bare showing severe intergranular...
Robot-assisted surgery is being widely used as an effective approach to improve the performance of surgical procedures. Autonomous control robots essential for tele-surgery with time delay and increased patient safety. In order safety reliability procedure tissue compression heating, a strategy simultaneously automating task presented in this paper. First, electrosurgical such vessel closure that involves heating has been modelled multiple-input–multiple-output (MIMO) non-linear system...
The first virtual-reality-based simulator for Natural Orifice Translumenal Endoscopic Surgery (NOTES) is developed called the Virtual Trainer (VTESTTM). VTESTTMaims to simulate hybrid NOTES cholecystectomy procedure using a rigid scope inserted through vaginal port. hardware interface designed accurate motion tracking of and laparoscopic instruments reproduce unique hand-eye coordination. haptic-enabled multimodal interactive simulation includes exposing Calot's triangle detaching gall...
Robotic surgery is being used widely due to its various benefits that includes reduced patient trauma and increased dexterity ergonomics for the operating surgeon. Making whole or part of surgical procedure autonomous increases safety will enable robotic platform be in telesurgery. In this work, an Electrosurgery involves tissue compression application heat such as coaptic vessel closure has been automated. A MIMO nonlinear model characterizing stiffness conductance under was feedback...
Four different impregnation methods, namely ultrasonic co-impregnation, stepwise impregnation, co-impregnation and were used to prepare Cu/B/Ca/Al2O3 catalyst. The effects of ultrasonic-assisted on the physicochemical properties, morphology hydrogenation performance sec-butyl acetate investigated, difference between was further explored. catalysts characterized by inductively coupled plasma atomic emission spectrometry, X-ray diffraction, scanning electron microscopy, Transmission microscope...
AISI 431 martensitic stainless steels (MSS) with 2.5 wt% Cu were fabricated via laser-directed energy deposition additive manufacturing followed by single-step tempering treatment. The influences of different times at 600 °C on microstructure and mechanical properties the as-deposited 431-2.5Cu MSS have been explored analyzed. specimen primarily consisted lath martensite, austenite M23C6 carbide. After treatment °C, Cu-enriched (ԑ-Cu) nano-precipitates reverse can be formed promoted...
