目的 合理选用摩擦偶件材料,以减缓Ni3Al基涂层宽温域内的摩擦磨损。方法 分别以WC-Co和316L为摩擦偶件,研究25~800 ℃内其对Ni3Al基涂层润滑和磨损机理的影响。采用高温硬度仪测试摩擦偶件在不同温度时的硬度,采用附带能谱仪的扫描电子显微镜观察磨损表面、磨斑和磨屑的形貌并测试成分,采用拉曼散射仪测试磨损表面和磨斑的成分。结果 在25~800 ℃,随温度的升高,两种摩擦副的摩擦系数具有一致的变化规律。与WC-Co对摩时,涂层在各温度下均具有低磨损率,且随温度升高,磨损率呈下降趋势。在25~200 ℃,与316L对摩时,涂层主要表现为粘着磨损和磨粒磨损,而与WC-Co对摩时,涂层在高接触应力下发生塑性变形,抑制Ag润滑相析出和涂层剥落,使其较前者具有高摩擦系数和低磨损率。在400 ℃,与WC-Co对摩时,高接触应力下产生的摩擦热促使涂层发生轻微的氧化,形成NiO和NiCr2O4,使其减摩性能优于Ni3Al/316L摩擦副。在600~800 ℃,与316L对摩时,涂层由严重的粘着磨损转变为氧化磨损;而与WC-Co对摩时,涂层由氧化磨损和剥层磨损转变为氧化磨损。此外,800 ℃时,Ni3Al/316L摩擦副的摩擦磨损发生在光滑润滑膜与粗糙转移膜之间,而Ni3Al/WC-Co摩擦副发生在光滑的润滑膜与转移膜之间。结论 在25~800 ℃,涂层与316L和WC-Co对摩时均具有良好的减摩性能,且与WC-Co对摩时具有更优的耐磨性能。 |

The paper reasonably selects the counterpart to shut down the friction and wear of the Ni3Al-based coating in a wide temperature range. The WC-Co and 316L were used as counterparts, respectively, and the effect of the counterparts on the lubrication and wear mechanism of Ni3Al-based coating within 25~ 800 ℃ was investigated. The hardness of the counterparts at different temperatures were tested by a high-temperature hardness tester. The morphology and composition of the worn surface of coating, the counterpart worn surface and debris were observed and analyzed by a scanning electron microscope with an energy spectrometer. The composition of the worn surface and worn surface of the counterparts were characterized by a Raman scattering instrument. The results showed that the friction coefficient of the two friction pairs had a consistent change law with the increase of temperature within 25~800 ℃. When sliding against WC-Co, the coating had lower wear rate at all temperature, and the wear rate decreased with the increasing of temperature. When sliding against 316L at 25~200 ℃, the wear mechanism of the Ni3Al/316L friction pairs was dominated by adhesive wear and abrasive wear. While the coating happened plastic deformation under high contact stress, which inhibited the precipitation of lubricating phase Ag and the peeling of coating, making it had higher friction coefficient and lower wear rate than the former. At 400 ℃, the frictional heat generated under the high contact stress promoted slight oxidation to form NiO and NiCr2O4, which made its anti-friction performance better than Ni3Al/316L friction pairs. Within 600~800 ℃, the wear mechanism of the Ni3Al/316L friction pairs changed from severe adhesive wear to oxidative wear, while the Ni3Al/WC-Co friction pairs transformed from oxidative wear and peeling wear to oxidative wear. Within 800 ℃, the friction and wear of Ni3Al/316L friction pairs occured between the smooth lubrication film and rough transfer film, while the Ni3Al/WC-Co friction pairs occurred between the smooth lubrication film. Within 25~800 ℃, the coating had good anti-friction performance when sliding against 316L and WC-Co, and it had better wear resistance when sliding against WC-Co. |
