摘要:
采用Bruker UMT-3 Tribolab摩擦磨损仪测试了与宝山钢铁股份有限公司共同开发的破冰船用低温钢板10CrMn2NiSiCuAl在不同环境温度下的摩擦磨损性能,利用轮廓扫描仪和扫描电子显微镜表征了磨痕及磨屑的表面形貌,采用电子能谱(EDS)以及X射线衍射谱(XRD)分析了磨屑表面的化学元素及成分,进而推断其磨损机制。结果表明:环境温度对摩擦磨损的性能有显著影响,当环境温度为20℃时,摩擦磨损形式以疲劳失效、氧化磨损和黏着磨损为主,磨痕表面的过渡层能够降低摩擦系数,减少磨损量,表面磨损产物主要为Fe2O3和Fe3O4;随着环境温度降低至-20℃,磨损机制转变为微切削作用下的磨粒磨损和塑性变形,磨痕表面出现犁沟形貌,磨损产物主要为Fe元素,磨屑的长宽比减小,出现球形磨屑,磨损量急剧增加。

Abstract:
Dry reciprocating friction and wear properties of a novel icebreaker steel (10CrMn2NiSiCuAl), which is co-developed by our group and BaoSteel Co., Ltd, were investigated using a UMT-3 Tribolab multi-specimen tester at different temperature. In this study, the wear scar morphologies and friction cross sections of the tested samples before and after the friction tests were recorded by coherence Scanning Interferometry.The surface morphologies, composition of worn surfaces and wear debris were characterized by scanning electron microscope, energy dispersive spectrometer and X-ray diffusion. Results show that the friction and wear properties are obviously affected by temperature. The wear mechanism is mainly fatigue failure accompanied with oxidation and adhensive wear at 20℃,which turn to abrasive wear and fatigue wear when the temperature decreases. The transition layer on the worn scar formed by Fe2O3 and Fe3O4 reduces the friction coefficient and wear rate. The declamation and spherical wear debris occur on the worn surface when the temperature decreases to -20℃, which aggravates the wear rate quickly.
