摘要

摘要 本文研究了摩擦复合材料成分中的缓蚀剂对摩擦装置中腐蚀过程和噪音产生的影响。制备了含有复合缓蚀剂作为目标添加剂的模型复合材料。采用 "平面-平面 "方案对摩擦复合材料进行了摩擦学测试。结果表明,钢制台体表面上的转移膜主要是由尺寸达 50 μm 的复合材料层状磨损颗粒形成的。X 射线光电子能谱数据证实,在转移膜中存在与摩擦材料主要成分有关的所有元素,包括腐蚀抑制剂。进行了气候试验。在使用不含腐蚀抑制剂的复合材料的摩擦副中,金属对体的连续腐蚀占主导地位,而点蚀会随着时间的推移而加剧。表面的腐蚀破坏程度达到名义接触面积的 90-95%。在摩擦复合材料成分中引入 1.5-3.0 wt % 的复合缓蚀剂,可将金属对撞体名义摩擦面积的腐蚀损坏程度降低 20-35%。在额定摩擦区域之外,发现金属对撞体表面区域的腐蚀损坏程度降低了 50-60%。在气候试验期间,对受到腐蚀的金属对体进行了三声测试。确定了摩擦副在 50 Hz-20 kHz 频率范围内产生的声压水平。结果发现,使用腐蚀抑制剂可降低噪音水平,而在 6-20 kHz 的高频区域,噪音水平最明显地降低了 7-30 分贝。

Effect of Corrosion Inhibitors in Compositions of Friction Composites on Corrosion Resistance of the Metal Counterbody and Noise Generation during Friction

In this paper, we study the effect of corrosion inhibitors in compositions of friction composites on corrosion processes and noise generation in friction units. Model composites containing complex corrosion inhibitors as target additives were prepared. Tribological tests of the friction composite were performed using the “plane-to-plane” scheme. Transfer films on the surface of a steel counterbody are shown to be formed predominantly by laminar wear particles of the composite with sizes up to 50 μm. X-ray photoelectron spectroscopy data confirmed the presence in the transfer films of all elements related to the main components of the friction material, including corrosion inhibitors. Climatic tests were carried out. In a friction pair with a composite containing no corrosion inhibitor, continuous corrosion of the metal counterbody is shown to be predominant while pitting actively develops over time. The degree of corrosion damage to the surface reaches 90–95% of the nominal contact area. The introduction of a complex corrosion inhibitor into the composition of friction composites in an amount of 1.5–3.0 wt % was established to reduce the degree of corrosion damage to the nominal friction area of the metal counterbody by 20–35%. Outside the nominal friction area, the effect of reducing the degree of corrosion damage to the surface area of the metal counterbody by 50–60% was found. Triboacoustic tests were carried out on metal counterbodies subject to corrosion during climatic tests. Levels of sound pressure produced by the friction pair in the frequency range of 50 Hz–20 kHz are determined. The use of corrosion inhibitors was found to lead to a decrease in noise levels while the most significant decrease of 7–30 dB occurs in the high-frequency region of 6–20 kHz.
