摘要 ：
Centrifugal self-propagation high-temperature synthesis (SHS) is a newly developed composite preparation technique by which a ceramic-alloy-carbon steel multilayer composite tube can be prepared. The hot deformation behaviors of the alloy steel layer at 800 degrees C-1000 degrees C, strain rates of 0.01 s(-1), 0.1 s(-1), 1.0 s(-1)and 10 s(-1)were studied by Gleeble-1500 thermal simulator. Rheological curve characteristics were analyzed under different thermal compression processes and a phenomenological hyperbolic sinusoidal Arrhenius constitutive equation was established to characterize the rheological mechanics of the material. The results show that the alloy steel is sensitive to temperature and strain rate, and its value of true stress decreases with the increase of temperature and strain rate. Thermal deformation process is the interaction between work hardening and dynamic softening, which is accompanied by the increase and extinction of dislocations. Under the strain rate of 10 s(-1), the stress-strain curve has a significant decrease when the strain exceeds 0.5. According to the observation of microstructure, this phenomenon can be attributed to the micro-crack generated by the local instability flow in the denatured zone. With the strain rate decreases, the softening mechanism of the alloy changes from dynamic recovery to dynamic recrystallization. The calculation results of the Arrhenius constitutive equation (AARE = 6.54 %,R = 0.99452) indicate that the model can predict the flow stress of the alloy accurately.

摘要 ：
The anticorrosion mechanism of Al-Ti-Si-RE coating in the environment of simulated deep sea was investigated using electrochemical measurement and micro-analysis. The result shows that Al-Ti-Si-RE coating possesses better corrosion resistance at hydrostatic pressure than at atmospheric pressure. After 480 h immersion at 3 MPa, a platform similar to a passivation region occurs in the anode of the potentiodynamic polarization curve because corrosion products block the corrosion channels. At the same time, at hydrostatic pressure, electrochemical impedance spectroscopy (EIS) indicates that Al passive film dissolves within 6 h of immersion, then tends to be stable after 12 h, and hardly changes between 300 and 480 h. To further analyze the original corrosion process, electrochemical noise (EN) of 0 similar to 64 ks at 0.1 and 3 MPa was measured, which quantificationally described the corrosion process from passive film dissolving to corrosion product fast-forming to stabilization. From morphology observation and X-ray diffraction (XRD) analysis, the rich Ti phase (Ti-Al intermetallics, etc) of the coating is cellular and has good corrosion resistance, whose construction could fix the Al oxide inside the coating, and thicken the coating to inhibit the corrosion.

摘要 ：
The thermal shock resistance and electrochemical corrosion behaviors of Al-Ti-Si-RE coating before and after thermal shock were investigated. The results show that the Al-Ti-Si-RE coating could keep good thermal shock resistance at 500 degrees C, and the electrochemical corrosion resistance before and after thermal shock does not decline sharply, which is caused by more metallurgical combinations between the coating and the substrate due to the reaction heat of Ti and Al in the high speed electric arc spraying process. At the same time, by transmission electron microscopy (TEM) observation, the grain sizes of the coating are small, and Al and Ti-Al intermetallics have a good coherency, which could all reduce the coating cracking sensitivity. In addition, Al-Ti-Si-RE coating has a good cage construction, whose voids and coating cracks could be sealed by Al oxides, and it could play the role of self-sealing and self-healing, and make the coating thicker with good resistances of thermal shock and electrochemical corrosion.

摘要 ：
High velocity arc spraying (HVAS) process was used to deposit Al-Ni-Y-Co amorphous and nanocrystalline composite coating on AZ91 magnesium alloy substrate. The microstructure of the coating was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS) and transmission electron microscopy (TEM). The results show that the coating with thickness of 500 mu m presents a dense layered structure with low porosity (1.8%). The coating consists of amorphous, nanocrystalline, and crystalline phases. The microhardness was measured by a microhardness tester. The average values of Vickers hardness for the Al-Ni-Y-Co coating, pure Al coating and AZ91 alloys are about HV0.1 310, HV0.1 70, and HV0.1 60, respectively. The electrochemical corrosion resistance of the coating in 5 wt% NaCl aqueous solution was also investigated, and the results showed that the Al-Ni-Y-Co coating exhibits better corrosion resistance than pure Al coating and AZ91 magnesium alloy.

摘要 ：
The corrosion behavior of Ti-Al pseudo-alloy coating under high hydrostatic pressure were investigated using electrochemical measurement and microstructure analysis. The results show that the corrosion resistance of Ti-Al pseudo-alloy coating remains excellent at 6 MPa hydrostatic pressure. It is because rich Ti phase performs the cage construction as an inert electrode and rich Al phase offers cathode protection to steel as the sacrifices. At the same time, the cage construction of rich Ti phase is full of corrosion products of Al, so the coating resistance is improved due to the effect of high self-sealing.
