| E-2000 Powder feeder | 1. The powder feeder is a high-precision powder feeding mechanism based on the principle of toothed dial with vibration structure and gravity falling, with uniform powder output and wide particle size range. 2. After the top cover is sealed, the powder condition in the powder cylinder can be clearly seen through the visual transparent observation window on the powder cylinder. 3. Nitrogen or argon with small flow is used as powder gas. The powder is rotated to the powder outlet along with the powder tray at the bottom and enters into the spray gun together with the powder gas. 4. Adopting the latest international turnover structure, it is convenient to clean the powder, which can be discharged from the lower mouth, or can be poured from the barrel body. | 1. Powder feeding: toothed dial 2. Cleaning method: barrel body flip 3. Volume of powder storage tube :2L 4. Powder feed gas: nitrogen 5. Powder feeding air pressure: 0.15-1.2mpa 6.

HA-2000 has many functions and features, and its advantages are mainly reflected in the following aspects:
1) Touch screen operation, the design structure of the equipment adopts full closed-loop automatic control structure, the gas is all controlled by pressure sensors imported from the United States and pressure regulating valves imported from Japan, the pressure can be monitored in real time and automatically reach the set value of the process.
2) The fuel is propane and the combustion-supporting agent is air, which is the safest combustion mode among the gas models in the market at present;
3) The structure of the spray gun is designed according to the principle of the rocket generator. The flame flow speed reaches over 2000m/s, with large output power and stepless adjustment;
4) The spray gun adopts axial center powder feeding. This new injection method makes the powder dissolve well and distribute evenly in the whole flame, which improves the coverage efficiency and coating quality;
5) It has the function of process recipe storage and invocation. Parameters can be added, modified and saved.
6) The system fuel adopts full closed-loop design, modular design, high-performance PLC control, safe and simple operation;
7) The coating produced has excellent performance with low porosity less than 1% (average porosity less than 0.5%) and high spray efficiency (up to 30KG powder per hour).
With the development of aviation, aerospace and civil technology, the temperature requirement of hot end parts is higher and higher, which has reached the limit of superalloy and single crystal materials. Take the heated parts of the fuel turbine, such as nozzle, blade and combustion chamber, for example, they are in the harsh environment of high-temperature oxidation and high-temperature airflow erosion, bearing the temperature as high as 1100ºC, which has exceeded the limit temperature (1075ºC) for the use of high-temperature nickel alloy. The metal of high strength, high toughness and high temperature resistance of the ceramic was prepared by combining the advantages of thermal barrier coating can solve the above problems, it can have the effect of heat insulation, anti-oxidation, anti-corrosion, has been in the hot end of steam turbine, diesel generators, jet engines on material has a certain application, and extend the service life of the hot end parts.
Thermal barrier coatings can significantly reduce the temperature of the substrate, have high hardness, good chemical stability, prevent high temperature corrosion, prolong the service life of hot end parts, improve engine power and reduce fuel consumption, etc. The emergence of TBCS has opened up a new way to greatly improve the performance of aeroengine. Since the 1970s, the United States, the United Kingdom, France, Japan and other developed industrialized countries have been competing to develop TBCS coating, and a large number of applications in blade, combustion chamber, heat insulation screen, nozzle, flame tube, tail nozzle and other hot end parts of the aircraft engine.
Thermal barrier coatings (TBCs) have been applied to turbine blades of aircraft engines in China, and some TBCs have been sprayed on turbine blades, and some initial achievements have been made. The application of thermal barrier coating technology can greatly improve the comprehensive performance of gas turbine engines and ground, prolong its service life, is one of the key technology of high performance engines and gas turbine development, with China's large aircraft, ground gas turbine, solid fuel engine technology advances, the demand for thermal barrier coating will be more and more big, Thermal barrier coatings (TBCs) will be widely used in hot end parts in aerospace, naval ships, nuclear industry, automobiles and other fields. At the same time, thermal barrier coating manufacturing process and equipment will be continuously improved, designers will have a more comprehensive understanding of thermal barrier coating, thermal barrier coating technology personnel will be more skilled.
