Different amounts of ink, made up almost entirely of a frit that devitrified abundant small crystals of anorthoclase, were applied by inkjet printing onto a traditional unfired glaze substrate. The rheological properties of the ink and porous texture of the unfired glaze substrate were characterized. The fired coatings were analyzed by SEM–EDX to determine the elemental composition at different surface depths, and their microstructure was observed. The results confirmed the validity of the ink penetration model, developed in a previous study, for describing the composition profile in inkjet coatings as a function of the applied amount of ink and pore size and volume in the unfired glaze substrate relative to average ink particle size. Microhardness and indentation modulus of the fired glaze substrate without an ink application and of the fired ink‐containing coatings were determined. The values of these properties were verified to fit a Weibull distribution function. The coatings containing an ink application at 400 and 600 dots per inch (dpi), respectively, displayed the best mechanical behavior. The study confirmed that inkjet printing a suspension with appropriate physico‐chemical characteristics onto an unfired glaze substrate substantially improved the aesthetic characteristics and mechanical properties of the resulting fired coating.

通过喷墨技术改善涂层的机械和美学性能

通过喷墨印刷将不同量的墨水（几乎完全由能使大量的正钙铝石小玻璃失透的玻璃料组成）通过喷墨印刷法施加到传统的未烧制釉料基材上。表征了油墨的流变性质和未烧制的釉料基材的多孔质地。用SEM-EDX对烧成的涂层进行分析，以确定不同表面深度的元素组成，并观察其微观结构。结果证实了先前研究中开发的墨水渗透模型的有效性，该模型用于描述喷墨涂料中的成分分布与墨水施加量以及未烧制釉料基质中的孔径和体积相对于平均墨水粒径的关系。 。测定未施加油墨的烧成釉基材和含油墨的烧成涂层的显微硬度和压痕模量。验证了这些属性的值以拟合Weibull分布函数。分别以每英寸400点和600点（dpi）的速度施加墨水的涂料显示出最佳的机械性能。该研究证实，将具有适当理化特性的悬浮液喷墨印刷到未烧制的釉料基材上，可以大大改善所得烧成涂层的美学特性和机械性能。表现出最佳的机械性能。该研究证实，将具有适当理化特性的悬浮液喷墨印刷到未烧制的釉料基材上，可以大大改善所得烧成涂层的美学特性和机械性能。表现出最佳的机械性能。该研究证实，将具有适当理化特性的悬浮液喷墨印刷到未烧制的釉料基材上，可以大大改善所得烧成涂层的美学特性和机械性能。
