Micro-arc oxidation (MAO) treatment with various voltages was carried out on Ti alloys in 10% H2SO4 aqueous solution to enhance surface wettability for biological application. The effects of applied voltage the morphology, phase constituents, functional group, roughness and MAO coatings were investigated comprehensively. Increasing significantly change morphology coatings. Higher are favorable form higher fraction rutile phase, larger micro-pores roughness. apparent contact angle decreases...
NPCS with an extreme fine microstructure displayed superior sono-Fenton-like catalytic activity compared to NPC.
The mechanical properties and corrosion performance of the N10276 alloy welded joint were investigated with nano-hardness testing electrochemical measurement. results showed that solidification mode changes from equiaxed crystal to columnar center weldment fusion zone. With increase immersion times, diameter capacitance arc impedance modulus increase, resistance HAZ decreases. strengthening effect metal was more obvious than heat affected zone for nickel-based especially in coarse grained...
An analytical model is developed to predict residual stresses formed during plasma cladding process. This based on the force and moment balances misfit strain caused by differential coefficient of thermal expansion (CTE) substrate layers cooling. The can be implemented a simple programming. Residual predicted from knowledge material properties, temperature specimen dimensions. are calculated after each layer rather than as whole. Specific results obtained for distribution within Co-based...
Shielded metal arc butt welded joints for 9%Ni steel using nickel-based filler were analyzed by optical microscopy, scanning electron microscope, as well transmission microscopy. The nanoindentation method was used to study the correlation between structure and micromechanical properties of fusion joint. results show that there is a microstructural evolution from melted deposit base steel. A significant coarse lath martensite-bainite mixture has been obtained in close boundary while retained...
Influence of solid solution temperature on microstructures and corrosion properties CoNiCrMo alloy were investigated by means optical microscopy (OM), scanning electron microscope (SEM) electronic differential system. The resistance in 0.9%NaCl aqueous was also investigated. results indicated that with the increase treatment temperature, dendrites gradually disappeared. Thus, decreased. When is 1200ºC, almost disappeared most carbide dissolved, begins to spheroidization. treated at 1000ºC...
Unreasonable weights of position and orientation data in the robot pose calibration model lead to low accuracy or even divergence parameter identification. This article presents a kinematic method based on minimal error model, separating parameters process. A is built Product Exponentials (POE) formula adjoint transformation. non-singular with complete obtained by removing redundant The linear mapping corresponding twist derived differentiating are separately identified using least-squares...
Transmission electron microscopy (TEM) image drift correction has been effectively addressed using diverse approaches, including the cross correlation algorithm (CC) and other strategies. However, most of strategies fall short achieving sufficient accuracy or cannot strike a balance between time consumption accuracy. The present study proposes TEM strategy that enhances without any additional consumption. Unlike CC matches pixels one by one, our approach involves extraction multiple feature...
The effect of dendritic structure and secondary phases on the fatigue crack propagation mechanism ERNiCrMo-3 weld metal was investigated in present study. Element segregation caused severe lattice distortion interdendritic region, which led to instability rates, resulting considerable differences mechanical properties between dendrite core region. limited plastic deformation capability region contraction local zone at tip, increased stress concentration accelerated propagation. Meanwhile,...
