为提高金属部件的工作寿命,为减少金属基体腐蚀和磨损的陶瓷涂层已应用了许多年,1986年美国的一项技术突破,将陶瓷涂层成功地应用于高温,更加扩大了这种涂层的应用范围。从而提高了金属基体和耐火材料基体的工作寿命,并且获得了15～30％的节能效果。目前使用的陶瓷涂层有两大类: 用于金属基体涂层的有硅—铝,球形粘土—硅。用于耐火材料基体的涂层有氧化锆,锆—铝—硅等。一、用于金属的陶瓷涂层用于金属的硅—铝涂层为水基、无毒、不可燃类。最高连续工作温度为1038℃,短
To improve the working life of metal parts, ceramic coatings have been used for many years to reduce the corrosion and wear of metal substrates. A 1986 U.S. technology breakthrough successfully applied ceramic coatings to high temperatures and extended this coating Layer of application. Thereby increasing the working life of the metal matrix and refractory matrix, and obtained 15 to 30% energy saving effect. There are two major types of ceramic coatings currently in use: silicon-aluminum, spherical clay-silicon for metal matrix coatings. Coatings for refractory substrates include zirconia, zirconium-aluminum-silicon and the like. First, the ceramic coating for metal Silicon - aluminum coating for the metal is water-based, non-toxic, non-flammable class. The maximum continuous working temperature is 1038 ℃, short
