采用相同的陶瓷骨料(SiO2+Al)、添加剂(MgO+CrO3)和固化工艺,分别以磷酸铝和水玻璃为粘接剂,在Q235钢上制备陶瓷涂层,对其相成分、微观形貌、热震性能以及耐蚀性能进行了分析测试,讨论了粘接剂对涂层耐蚀性的影响。结果表明,尽管以磷酸铝为粘接剂的陶瓷涂层在固化过程中产生少量孔隙,但仍具有比以水玻璃为粘接剂的陶瓷涂层更优异的抗热震性能以及耐酸、碱、盐腐蚀性能。
The same ceramic aggregate (SiO2 + Al), additive (MgO + CrO3) and curing process were used to prepare ceramic coatings on Q235 steel with aluminum phosphate and water glass as bonding agent respectively. The phase composition, microstructure Appearance, thermal shock resistance and corrosion resistance were analyzed and tested. The influence of adhesive on the corrosion resistance of the coating was discussed. The results show that although ceramic coatings with aluminum phosphate as a binder produce a small amount of voids during curing, they still exhibit better thermal shock resistance and resistance to acids, alkalis and alkalis than ceramic coatings with water glass as a binder, Salt corrosion performance.
