Machining is an important part of the manufacturing process in the engineering field. Turning is one of these areas. At present, almost exclusively exchangeable cutting inserts are used in production machining. The article describes the research in the field of their wear, where the electron microscopy was used to evaluate the results. Electron microscopy is a very important aid in research in many are-as not only of human activity and also is the important aid in the field of mechanical engineering and manufacturing technologies. The results thus obtained can make in a given area it clearer and better document the resulting situation. Within the experiments, selected cutting inserts were used and the given material was machined. The electron microscope Tescan Vega 3, which is available at the workplace where the experiment was conducted, was used to evaluate the resulting wear. In the frame of experiments was also performed the composition analyze of used cutting inserts. Analyzes of the machined material were also performed to confirm the declarations from the supplier.
机械加工是工程领域制造过程的重要组成部分。转弯就是其中之一。目前,在生产加工中几乎只使用可交换的切削刀片。本文介绍了在其磨损领域的研究,其中使用电子显微镜对结果进行了评价。电子显微镜不仅是研究人类活动的重要工具,也是机械工程和制造技术领域的重要工具。这样得到的结果可以使给定区域的结果情况更清楚、更好地记录下来。在实验中,使用选定的切削刀片,并对给定的材料进行加工。Tescan Vega 3电子显微镜(在实验进行的工作场所可以买到)被用来评估由此产生的磨损。在试验框架内,对使用过的切削刀片进行了成分分析。还对加工材料进行了分析,以确认供应商的声明。

The Effect of Single-Wall Carbon Nanotubes Content on the Properties of Polyurethane Nanocomposite 单壁碳纳米管含量对聚氨酯纳米复合材料性能的影响
Q4 ENGINEERING, MANUFACTURING Pub Date : 2023-11-14 DOI: 10.21062/mft.2023.079

This study aimed to investigate the influence of single-wall carbon nanotube (SWCNT) content on the mechanical properties of polyurethane (PU) nanocomposites. The SWCNT content varied from 0 wt% (reference sample) to 2 wt%. Tensile, hardness and Charpy impact tests as well as dynamic me-chanical analysis (DMA) were performed. Based on the test results it was observed that an increase in the content of single-wall carbon nanotubes resulted in significant improvements in material strength and stiffness. Furthermore, atomic force microscopy (AFM) was used to examine microsurface to-pography of the samples and to obtain spectroscopic curves, based on which local elasticity was eval-uated. Overall, performed measurements indicate that the incorporation of SWCNTs into PU matrix makes resultant nanocomposite stiffer and more resistant to deformation. The results highlight the potential of SWCNTs as effective reinforcement of polyurethane-based nanocomposites.
本研究旨在研究单壁碳纳米管(SWCNT)含量对聚氨酯(PU)纳米复合材料力学性能的影响。swcnts含量从0 wt%(参考样品)到2 wt%不等。进行了拉伸、硬度和夏比冲击试验以及动态力学分析(DMA)。根据测试结果,单壁碳纳米管含量的增加导致材料强度和刚度的显著提高。此外,利用原子力显微镜(AFM)对样品的微表面形貌进行了检测,并获得了光谱曲线,以此评价了样品的局部弹性。总体而言,所进行的测量表明,将SWCNTs掺入PU基体使所得纳米复合材料更坚硬,更耐变形。研究结果强调了SWCNTs作为聚氨酯基纳米复合材料的有效增强材料的潜力。

Determination of the Effect of Deformation on the Corrosion Resistance of Zn-Al-Mg Coated Sheets 变形对锌铝镁镀膜板耐蚀性影响的测定

In the automotive industry, deep-drawn sheet metals are widely used and protective coatings are ap-plied to its surfaces to improve certain performance properties (e.g. to increase corrosion resistance). Sheets with these coatings are stressed during the forming process of the part and cracking of the protective coating may occur. The main goal of this paper is to determine the resistance of a Zn-Al-Mg based protective coating to uniaxial and triaxial stresses, and also to determine how effective anticorrosion resistance the coating provides to the base steel matrix in the event that cracking occurs. It has been shown that both uniaxial and triaxial loading leads to a failure of the Zn-Al-Mg coating integrity. Salt spray corrosion tests of 3 and 6 weeks were subsequently performed on both deformed and undeformed base material samples. These tests showed that a continuous Al2O3 layer is formed between the steel matrix and the coating, which, irrespective of the formation of cracks in the coating, is the main contributor to the increase in corrosion resistance of the sheet.
在汽车工业中,深拉深金属板被广泛使用,并在其表面涂上保护涂层以改善某些性能(例如增加耐腐蚀性)。具有这些涂层的薄板在零件成形过程中受到应力,保护涂层可能发生开裂。本文的主要目的是确定Zn-Al-Mg基保护涂层对单轴和三轴应力的抵抗能力,以及确定在发生裂纹的情况下涂层对基体钢的有效抗腐蚀能力。结果表明,单轴和三轴载荷均会导致Zn-Al-Mg镀层完整性的破坏。随后对变形和未变形的基材样品进行了3周和6周的盐雾腐蚀试验。试验结果表明,在钢基体和涂层之间形成了连续的Al2O3层,这与涂层中裂纹的形成无关,是提高板材耐蚀性的主要原因。
