TRAINING 59 Graduation Thesis GVHD: Assoc Prof TRAN NGOC DAM, Ph.D Chapter 7: CONCLUSION AND DEVELOMENT DIRECTION FACULTY FOR HIGH QUALITY TRAINING 60 Graduation Thesis GVHD: Assoc Prof TRAN NGOC DAM, Ph.D 7.1 Conclusion Through research and research on green treatment technologies and the great influence of this technology in the field of surface treatment We have proposed and implemented the development and manufacture of an effective machine treatment system using plasma technology directly applied to the present: " Metal surface treatment system applying plasma technology" Using many methods of analysis and comparison from different design options, we have come up with the optimal design principle for the system based on the basic surface treatment principle of plasma technology In this topic, we have successfully designed and manufactured a metal surface treatment system with a capacity of 2÷4m/min using plasma technology, initially meeting the group's goals Metal surface treatment systems applying plasma technology have the advantages:  Compact, easy to operate, maintain maintenance, minimize installation area  Plasma technology does not use chemicals for processing which further contributes to protection, safety and environmental friendliness  Energy saving, maximum shortened processing time while still producing the best results  High processing efficiency: the output surface quality meets national standards  Save installation, operation and maintenance costs With this topic, we want to provide an optimal solution for the treatment of metal surfaces with the application of plasma technology Thereby, helping to improve productivity, the quality of surface treatment brings a new breeze to the development of the country 7.2 Development direction After completing the design and manufacture of the metal surface treatment system, the team realized that the topic still had many shortcomings and offered some development directions as follows: Continue to research and develop the system, optimize energy to help the operation of the system use the lowest energy source but still achieve the highest efficiency Improve the automatic ability of the machine, the machine runs fully automatically, can run when the water quality is low Optimize investment costs for production and machine productivity FACULTY FOR HIGH QUALITY TRAINING 61
