In the article, the new concept of plasma-sprayed coatings for the cylinder liner was presented. The new type of powder containing WC-CrC-Ni with a 5 and 10 wt. % addition of nano-YSZ powder was plasma-sprayed on aluminum 2017 alloy samples. The selection of optimal plasma-spraying parameters was made taking into account the thickness, porosity, and hardness of the coatings. For the coatings obtained according to the developed parameters, the analysis of their microstructure, chemical, and phase composition was performed. At the next stage, the friction coefficient of the developed coatings was tested and compared with the properties of a classic cast-iron cylinder liner. The obtained results suggest that the developed type of coating might be used for cylinder liner applications after a deeper friction analysis.
在该文章中，提出了用于气缸套的等离子喷涂涂层的新概念。将含有WC-CrC-Ni且添加了5 wt.%和10 wt.%纳米YSZ粉末的新型粉末等离子喷涂在2017铝合金样品上。考虑到涂层的厚度、孔隙率和硬度来选择最佳的等离子喷涂参数。对于根据所制定参数获得的涂层，对其微观结构、化学和相组成进行了分析。在下一阶段，对所开发涂层的摩擦系数进行了测试，并与经典铸铁气缸套的性能进行了比较。所得结果表明，经过更深入的摩擦分析后，所开发的涂层类型可用于气缸套应用。
