Nano aluminum/titanium oxide spraying process was explored and the mechanical properties were studied. Atmosphere plasma spraying method was used for preparing aluminum/titanium oxide ceramic coating with nano structure, and fixing spraying current, spraying distance and powder feeder rotation speed. Four groups of hot spraying specimens with different processes were prepared by adjusting the main air pressure and spraying voltage, which optimized the preparation process. The bonding strength, microstructure, hardness, fracture toughness, cupping property and thermal shock resistance after optimization were represented, and the friction and wear performances of nano ceramic coating in the ball disc mode were also represented. The optimal nano ceramic coating was AT13, which was determined by the microstructure hardness, crack resistance and fracture toughness data of coating. Nano ceramic coating had higher bonding strength and hardness, and nano tissue of original powder inherited excellent cupping resistance of nano coating, so the toughness is obviously better than that of traditional micron coating. After water quenching cycle test at 400°C for 50 times, the coating did not lose efficacy at all. In the ball disc friction wear under high load, the wear extent of nano ceramic coating is low, and the friction coefficient is stable, which shows good wear resistance. Nano aluminum oxide ceramic coating has high bonding strength, excellent cupping performance, wear resistance, good comprehensive mechanical properties, so it could be used for rigid working environment.
With the national emphasis on environmental issues is gradually increasing, more and more experts and scholars on the environmental art design system of more and more research. The requirement of environmental art design system is getting higher and higher. Traditionally, two-dimensional images are used to describe environmental art geography, and the environmental information obtained lacks intuitiveness and interactivity. The purpose of this paper is to realize the social sharing and service of environmental art information so that the public can conveniently enjoy the risk warning service of environmental information. Starting from the framework reconstruction of system construction, this paper takes the Web framework pattern as the basic framework of system realization, and creates different entity models and terrain models in virtual environment through Creator modeling software. After collecting the original environmental data, the edge processing of the environmental data is carried out to produce the 3D environmental design system. In the process of 3D virtual reproduction of the environment, Vega driver software was used to shape the Web 3D scene of the environment, and the Marine environment module in Vega was used to realize dynamic and static environment simulation and simulation effect. The experimental results show that the display effect of the environmental art design system constructed in the Web mode is more realistic, intuitive, interactive and satisfactory.
The landscape design as the human living space geographical composition is very important part of ecological system, the existence of regional landscape not only provides residents with a versatility, layout, balanced, open outdoor public space of free activities, whereas in the past the landscape design of the system is designed in accordance with the local geographical factors, more is not fully consider various comprehensive factors. The purpose of this paper is to properly introduce the existing technology based on distributed theory such as remote sensing positioning and data analysis to optimize the landscape design system. By using the data sensing module of Hadoop landscape design system and the distributed coding technology for genetic algorithm, the application of 3D landscape design is carried out. Its characteristic and innovation is the fusion of distributed storage and cluster, the design of big data dynamic storage system, analysis of its operation depends on the analysis and algorithm technology, compared with the final system operation effect. Experimental results show that the landscape design system based on distributed very well to the geographical location, topography, the surrounding environment, traffic conditions, historical and cultural factors, such as analysis, determine the theme of the landscape planning and design positioning, functional partition and content of ecological landscape, through the analysis of the landscape planning and design, take its long, avoid its short, problem solving, superposition of advantages, for a more reasonable and high quality to complete the landscape planning and design is of great significance.
