三、运用等离子喷涂技术进行修复 在热喷涂这类技术中,等离子喷涂是修复方法中应用最广的一种。这种方法的特点是,等离子流中的高温(15 000K)和粉末粒子的喷射速度可在较低的压力下达到300m/s和500m/s。实际上,它所能生成的涂层其各项性能完全可以满足工业应用的要求。 这些成就的取得,应归因于研制出了这方面的加工设备和新的喷涂方法。当代等离子流发生器的性能特点,是能够充分地将电能转换成热能,以及可在将粒子加速和熔化的过程中广泛加以应用。新的粉末材料其金属粒
Third, the use of plasma spraying technology to repair In the thermal spraying of such technologies, plasma spraying is the most widely used method of repair. The characteristic of this method is that the jet velocity of high temperature (15 000 K) and powder particles in the plasma stream can reach 300 m / s and 500 m / s at lower pressures. In fact, the coating it can produce has properties that meet the needs of industrial applications. These achievements have been attributed to the development of processing equipment and new spraying methods in this area. The performance characteristics of contemporary plasma flow generators are the ability to fully convert electrical energy into heat and to be widely used in the acceleration and melting of particles.
