Friction and wear properties of hydraulic components with ceramic/steel-to-steel pairs
Baofu Kou,Zhenshun Li,Zhang Zhang,Ruiqing Li 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.8
The friction coefficient and wear amount of ceramic/steel-to-steel pairs under various concentrations of high water-based emulsion, load size, and load frequency were investigated through friction and wear test, white light interference 3D surface profiling, scanning electron microscopy, and attached energy spectrometry. The friction and wear conditions of hydraulic components made of different materials are discussed. The ceramic-to-steel pair performs better than the steel-to-steel pair in friction reduction and wear resistance. When the load is 100 N, the frequency is 1 Hz and the concentration is 6 %, and the friction coefficient and wear amount of the ceramic-to-steel pair are the lowest. The degree of abrasive and ploughing wear of various friction pairs is directly proportional to the emulsion concentration and inversely proportional to the working load and frequency. The research results can provide guidance for the manufacture and application of ceramic valves.
