1st Power Spraying Symposium

On June 11, 2011, the Kinetic Metallization Seminar co-sponsored by Advanced Machinery Equipment Co., Ltd., Beijing Institute of Technology Surface Engineering Laboratory and American INOVATI Company was successfully held in Beijing Institute of Technology. This seminar carried out in-depth research and discussion on the relevant information of power spraying through technical lectures, interactive exchanges and other means. This seminar attracted the participation of many universities, research institutes, companies, and factories.

The meeting was presided over by Mr. Li Zhigang, general manager of Advanced Machinery Equipment Co., Ltd. Mr. Howard Gabel, CEO of INOVATI, a manufacturer of power spraying systems in the United States, gave a technical lecture on power spraying for the participants. Mr. Howard Gabel gave a detailed introduction to the composition of the power spray system, the basic working principle, the performance of the power spray coating and the application of power spray.

　　Power spraying is a new type of low temperature sonic spraying. The process of power spraying has a long air acceleration range and high air velocity (up to the speed of sound). The spray powder is heated at a low temperature and sent into the high-speed air flow for full acceleration. The particles are fully deformed during deposition, and extremely high coating performance can be obtained. The oxide content in the dynamic spraying coating is almost zero, the coating density is extremely high (porosity can be less than 0.1%), the interface is well bonded, the coating bonding strength is high, and in most cases the surface of the substrate does not need sandblasting treatment so that The interface pollution problem caused by surface blasting treatment is avoided. The ablation resistance of the MCrAlY coating prepared by this process is better than that of the high-pressure plasma spraying coating. Power spraying has now been widely used in dimensional repair, solar cells, anti-corrosion and wear resistance, high temperature anti-oxidation, polymer spraying and other fields.

Then, participants conducted further interactive discussions with Howard Gabel on issues such as the overlap of flattened particles during power spray deposition, the application fields of power spray, and whether power spray may replace cold spray in the future.

 Professor Ning Xianjin (right) and Howard Gabel (left) from the Power Spraying Laboratory of Beijing Institute of Technology had a friendly discussion on the design and modification of the power spraying system, and conducted in-depth exchanges on the research status and development direction of power spraying.

After the seminar, the participants visited the power spraying laboratory of Beijing Institute of Technology and observed the actual use of the power spraying system. Professor Ning Jinjin, head of the power spraying laboratory of Beijing Institute of Technology, exchanged precautions for power spraying with the participants, demonstrated the operation process of power spraying on the spot, and carried out spraying experiments. The actual spraying process fully demonstrates the characteristics of low noise and high deposition efficiency of power spraying.

With the joint efforts of the participants and the sponsor, this power spraying seminar was a complete success. This seminar showed everyone a new spraying process and promoted technical exchanges at home and abroad. In order to promote the development of thermal spraying application technology in my country, Advanced Machinery Equipment Co., Ltd. will hold more thermal spraying technology seminars in the future, and welcome everyone to participate.
