Processability, Microstructure, and Mechanical Property of Al-Si …
The processability, microstructure, and mechanical property of the SLM-fabricated Al-Si-Mg-Zr-Cu alloy are systematically studied. The results indicate that the sample exhibits good SLM processability at low laser power (250 W), with a maximum relative density of 99.8%.
Electrochemical Performance of Deep-sea Sacrificial Anode in …
Abstract. The electrochemical behaviour of deep-sacrificial anode developed was evaluated in a simulated deep-sea environment through electrochemical performance test, polarization and electrochemical impedance test. The results showed an excellent electrochemical performance of these anodes in deep-sea environment.
Properties of Flame Retardancy and Low Toxicity of Siloxane …
The forming process, mechanical property, flame retardancy and low toxicity of the glass fiber reinforced siloxane modified vinyl resin composites are studied.
Microstructures and Fatigue Crack Growth Rates of Domestic and …
The microstructures and fatigue crack growth behavior of domestic and imported 5083-H116 aluminum alloys were researched. Experimental results showed that the chemical constitutions of domestic and imported 5083-H116 aluminum alloys both met the standard requirements.
Research on Preparation of Magnesium Alloy/Binder Composite …
In this study, an internal mixer is adopted to mix polymer binder with magnesium alloy powders, and an extrusion machine is employed to prepare wire materials suitable for the fused deposition modeling (FDM) process. The influence of FDM process on the surface morphologies of the green billets is investigated.
Experimental Study on Laser Cladding Remanufacturing Process of …
The hot forging die often has to bear extremely high temperature and strong impact load in the working process, and it is very easy to fail due to wear, corrosion and thermal fatigue. In this study, the process experimentation of H13 hot forging die steel laser cladding technology is studied, and the Inconel 625 high-temperature alloy coating on the surface of H13 die steel is …
Research Progress in Application of Laser Cleaning Technology
The research status of laser cleaning at home and abroad is reviewed from three aspects of mechanism, equipment and application fields. The advantages and disadvantages of laser cleaning technology in aircraft maintenance, heavy machinery, automobile remanufacturing and other industrial applications are summarized, and the potential development ...
Development of a High Damping Copper Alloy Plate Using in …
Abstract. Development of a high damping copper alloy plates used in transmission system of ships is introduced and the influences of essential heat treatments on the microstructure and performance of the alloy is investigated.
