GATOR—GARD 是一种新的喷涂工艺。该工艺的最大特点是:等离子弧通过喷嘴时受到冷却和加速,金属或陶瓷粉末在喷嘴中均匀混合,并在平行的等离子能束流中迅速地加热、加速(温度为2700～3600°F,速度为1200～1500m/s)。这些动能极大、均匀受热的粉末微粒流喷射到基体上,生成密度极高、耐磨性很强、抗氧化、抗硫化的特殊涂层。下表给出三种不同喷涂工艺所得碳化钨涂
GATOR-GARD is a new spray process. The most prominent feature of this process is that the plasma arc is cooled and accelerated as it passes through the nozzle and the metal or ceramic powder is uniformly mixed in the nozzle and rapidly heated in a parallel plasma beam and accelerated at a temperature of 2700 to 3600 ° F, Speed of 1200 ~ 1500m / s). These extremely kinetic energy, even heated powder particles jet to the substrate, resulting in a very high density, wear resistance, anti-oxidation, anti-vulcanization of the special coating. The following table shows three different tungsten carbide coating process
