锆英石是重要的耐火材料,在低于1700℃下具有优异的热震性能、化学和结构的稳定性、低的热膨胀系数和低的导热系数,在冶金工业中有着广泛的用途。然而,其表面孔隙率通常在15%以上,会严重影响材料的抗侵蚀性能。采用高能CO2激光熔凝处理,能在不影响基材性能的前提下,获得致密的 Zircon is an important refractory material with excellent thermal shock resistance below 1700 ℃, chemical and structural stability, low thermal expansion coefficient and low thermal conductivity. It is widely used in the metallurgical industry. However, their surface porosity is usually above 15%, which can seriously affect the corrosion resistance of the material. The use of high-energy CO2 laser melting process, can not affect the substrate properties under the premise of obtaining a dense
