摘要
摘要 研究结果表明,沉积层中的缺陷对 08Kh14N5M2DL 钢级熔化试样的耐久性有影响,该试样在加热温度高达 800-900°C 的摩擦条件下工作,并在摩擦接触区承受较大载荷。沉积层中的缺陷表现为气孔、不熔合和断裂。通过 X 射线计算机断层扫描测定了进行摩擦试验的样品内部的缺陷。结果发现,无缺陷堆焊层的耐磨性会随着试验温度的升高和摩擦接触载荷的增加而降低。堆焊层内部存在微裂纹是显著降低耐磨性的关键。堆焊层中存在的孔隙对磨损的影响较小。
Wear Resistance of 08Kh14N5M2DL Steel Grade Having Deposited Kh25N10V8 Alloy Layer at Elevated Temperatures
The results are given for impact of defects in the deposited layer on the durability of melted samples made of 08Kh14N5M2DL steel grade operating under conditions of friction at heating temperatures up to 800–900°C and under significant loads in the tribological contact zone. Defects in the deposited layer are represented by pores, the lack of fusion, and fractures. The defects inside samples undergoing friction tests are determined using X-ray computer tomography. It is found that the wear resistance of the surfacing layer without defects decreases both with growing test temperature and with increasing load applied to tribological contact. The presence of a microfracture pattern inside the deposited layer is crucial to dramatically decrease wear resistance. The presence of porosity in the deposited layer affects the wear to a lesser extent.
期刊介绍:
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
