本文中提出了一种在45#钢表面构筑具备优异减摩耐磨性能的薄膜的简易方法.首先采用高浓度氢氧化钠溶液在钢表面制备沟槽状表面织构,然后沉积硬脂酸分子得到减摩耐磨薄膜.用扫描电子显微镜、原子力显微镜、接触角测量仪、X射线光电子能谱仪以及X射线衍射仪等手段表征了薄膜的形成机制、表面形貌和化学组分,并利用微纳米摩擦磨损试验机研究薄膜在干摩擦条件下的减摩耐磨特性.研究结果发现,在经化学刻蚀形成织构的钢表面所沉积的硬脂酸薄膜具有优异的减摩耐磨性能.
In this paper, a simple method of constructing a thin film with excellent anti-wear and anti-wear properties on 45 # steel surface is proposed.Firstly, grooved surface texture is prepared on the steel surface by high concentration sodium hydroxide solution, and then stearic acid molecules The anti-friction and wear-resistant films were obtained.The formation mechanism, surface morphology and chemical composition of the films were characterized by scanning electron microscopy, atomic force microscopy, contact angle measurement, X-ray photoelectron spectroscopy and X-ray diffraction Micro-Nano Friction and Wear Testing Machine The anti-friction and wear-resistant properties of films under dry friction conditions were studied.The results show that the stearic acid films deposited on the chemically etched steel surface have excellent anti-friction and anti-wear properties .
