The Mn₃B₇O₁₃Cl nanoparticle (~30 nm) has been prepared by sol‐gel method and characterised by powder X‐ray diffraction (XRD) and transmission electron microscopy (TEM). The tribological properties of prepared Mn₃B₇O₁₃Cl nanoparticle and the common nano‐Cu and nano‐Fe nanoparticles as antiwear additives with various concentrations in polyalphaolefin (PAO) base oil have been investigated. P_B values of nano‐Mn₃B₇O₁₃Cl added oil are superior to base oil, nano‐Cu and nano‐Fe added oil with the same content, and it reaches the value of 637 N. The wear scar diameter is 0.52 mm when the concentration is only 0.2 wt.%. And meanwhile, Mn₃B₇O₁₃Cl nanoparticle as efficient antiwear lubricant and commercial oil was measured in the sliding wear between tantalum strip and 52100 bearing steel ball by MFT‐3000 friction and wear tester at an optimised additive concentration (0.2 wt.%). Coefficient of friction of tantalum strips is reduced by 41.5% compared with that of the commercial oil. Surface morphology studies and X‐ray photoelectron spectroscopy (XPS) analysis have revealed that the prominent tribological behaviour of Mn₃B₇O₁₃Cl was caused by the formation of ~ 30‐nm tribofilm made of adsorbed boron and tribosintered nano‐Mn₃B₇O₁₃Cl. Therefore, Mn₃B₇O₁₃Cl nanoparticle has a potential to develop as friction‐reducing and antiwear lubricant in the sliding wear between tantalum strips and steel ball to avoid the severe wear.

Mn3B7O13Cl纳米粒子作为钽带与钢球之间滑动磨损的有效抗磨润滑剂的合成，表征和摩擦学评估

Mn ₃ B ₇ O ₁₃ Cl纳米粒子（〜30 nm）通过溶胶-凝胶法制备，并通过粉末X射线衍射（XRD）和透射电子显微镜（TEM）表征。研究了制备的Mn ₃ B ₇ O ₁₃ Cl纳米颗粒以及在聚α-烯烃（PAO）基础油中作为各种浓度的抗磨添加剂的常见nano-Cu和nano-Fe纳米颗粒的摩擦学性能。纳米Mn ₃ B ₇ O _13的P _B值添加了Cl的油优于具有相同含量的基础油，添加有nano-Cu和nano-Fe的油，其值达到637N。当浓度仅为0.2 wt。％时，磨损痕迹直径为0.52 mm。同时，锰₃乙₇ ø ₁₃氯纳米粒子作为有效抗磨润滑剂和商业油状物通过MFT-3000的摩擦和磨损试验机的钽带和52100轴承钢球之间的滑动磨损以优化的添加剂浓度（0.2重量测量。％ ）。与商用油相比，钽带的摩擦系数降低了41.5％。表面形态学研究和X射线光电子能谱（XPS）分析表明，Mn ₃ B ₇ O具有突出的摩擦学行为。₁₃ Cl是由〜30 nm的摩擦膜形成的，该摩擦膜由吸附的硼和摩擦烧结的纳米Mn ₃ B ₇ O ₁₃ Cl组成。因此，Mn ₃ B ₇ O ₁₃ Cl纳米粒子有可能在钽带与钢球之间的滑动磨损中作为减摩和抗磨润滑剂发展，以避免严重磨损。
