Since 1910, Dr. Ruishixiaopu invented a flame spray device (ie, thermal spraying) since the thermal spray coating process technology has developed greatly in Foshan, especially since the 1980s, the application of thermal spray technology has made great achievement. From the tens of microns to several millimeters can be prepared in a coating, and easy to control, high coating efficiency, and low cost. When spraying production efficiency for a few kilograms to tens of kilograms per hour. However, as a surface treatment technology, it also has many shortcomings, mainly in the low thermal efficiency, material utilization is low, and the coating and the substrate wastage three lower strength. Compared with other types of thermal spray surface technology, thermal spray technology has its own characteristics: 1. Preparation of a variety of materials can be coated on a variety of substrates, including metals, ceramics, metals, ceramics, plastics, glass, wood , cloth, paper, almost all of the solid material. 2. The substrate temperature is low. Substrate temperature is generally between 30 ~ 200oC, small deformation Buying spray processing, heat-affected zone light. 3. flexible operation. Can be painted in different sizes and shapes of objects, particularly suitable for large-area coating, and in field operations. 4. Coating wide range of thicknesses. After supersonic spray apparatus utilizing kerosene as fuel, oxygen and the use of compressed air as oxidizer, kerosene and oxidizer control means to a certain pressure and flow delivered to the spray gun, by high performance liquid atomizing nozzle atomized into mist sprayed into the mixing Hardware spray gun combustion process, liquid mist formation by the spark plug ignition combustion temperature and high pressure gas, Laval gun to accelerate to supersonic. HVOF spraying powder powder feeding system into a supersonic jet from the Laval nozzle area of ??low pressure spray gun, after warming accelerates the jet ejected from the gun, high speed sprayed surface coating deposition. As the multi HVOF technique using oxygen and compressed air can be two kinds of accelerant, along with HVOF and HVAF functionality, speed and temperature of the flame in a large flow range continuously adjustable.
