Tribological tests in real conditions enable obtaining full data on the life of interacting machine parts. This article presents the results of operational tests on the elements of the support ring guidance system in a vertical ball-race mill. The guide and active armour operate under abrasive wear conditions with moderate-impact loads. The wear resistance of elements with overlay welding layers deposited with flux cored wire with a structure of high-alloy chrome cast iron and with a coating flame-sprayed with nickel-based powder was compared. The wear intensity of the overlay weld deposits was much lower than that of the sprayed coatings. The scope of this study also included the analysis of the chemical and phase composition, macro- and microscopic metallographic examinations, and the measurement of the hardness of the deposited layers and coatings.
在实际条件下进行的摩擦学测试能够获取有关相互作用的机器部件寿命的完整数据。本文介绍了立式球磨机支撑环导向系统元件的运行测试结果。导向装置和活动护板在有中等冲击载荷的磨料磨损条件下运行。比较了采用高合金铬铸铁结构的药芯焊丝堆焊层元件以及采用镍基粉末火焰喷涂涂层元件的耐磨性。堆焊层的磨损强度远低于喷涂涂层。本研究的范围还包括对化学成分和相组成的分析、宏观和微观金相检验以及对沉积层和涂层硬度的测量。
