中文摘要:
      目的 研究新型船用低温钢板的摩擦磨损性能。方法 采用UMT-2型多功能摩擦磨损实验机,测试了船用低温钢板在室温干态环境、不同载荷(10、20、30 N)、不同频率(2、5 Hz)下的往复摩擦试验行为。采用光学显微镜(OM)、扫描电子显微镜(SEM)分析了船用低温钢板的磨痕表面形貌,用光学轮廓仪分析了磨损表面轮廓,用EDS对试样磨损表面进行了成分分析。结果 随着试验法向载荷从10 N增加到30 N时,船用低温钢板的摩擦系数从0.51逐渐增加到0.63,磨损率先增加后降低,再逐渐增加。在相同载荷下,摩擦系数随着往复频率的提高而降低。载荷为30 N时,往复频率为5 Hz,摩擦2 h后,磨损断面轮廓宽度和深度分别为750 μm和3871 nm。接触面从磨粒磨损转向疲劳磨损,接触面出现氧化层、表面硬化层和转移层。结论 载荷较低时,船用低温钢磨损主要为氧化磨损和疲劳磨损;载荷增大时,接触面磨损出现疲劳磨损。同等载荷下,摩擦系数会随着移动速度的提高有所下降,接触面在摩擦热作用下形成的金属膜有助于降低表面粗糙度,减小摩擦系数。
英文摘要:
      The work aims to study reciprocating friction and erosion properties of novel marine arctic steel plates. Reciprocating friction test behavior of marine arctic steel plates was tested on UMT-2 multi-functional friction and wear tester provided with different loads (10, 20, 30 N) and frequencies (2, 5 Hz). Morphology of grinding cracks of the steel plates were analyzed with optical microscope and scanning electron microscope, profile of worn surface with optical profiler and worn surface composition with EDS. Wear rate firstly increased and then decreased as test normal load increased from 10 N to 30 N, and friction coefficient of the marine arctic steel plates increased from 0.51 to 0.63 gradually. Under the same load, friction coefficient decreased as the reciprocating frequency increased. Provided with reciprocating frequency of 5 Hz and load of 30 N. profile width and depth of the worn section was 750 μm and 3871 nm, respectively, after 2 h friction. Wear mechanism of the marine arctic steel plate transmitted from abrasive wear to fatigue wear, oxide layer, surface hardening layer and transfer layer were present on the contact surface. The wear mechanism of marine arctic steel plate is the combination of abrasive wear and fatigue wear under low load. Fatigue wear is present on the contact surface as the load increases. The friction coefficient decreases as the movement speed increases under the same load. The metal film forming under the effect of friction heat on the contact surface helps reduce surface roughness and friction coefficient.
