Abstract
Scanning electron microscopy and X-ray diffractometry are used to study the coating layer deposited on a CuSn10Pb10 bronze surface through electric spark machining with anode material having similar composition. X-ray studies of the phase composition indicate the presence of copper–tin phases (Cu, α-(Cu; Sn), Cu3Sn, ε-Cu3Sn, and Cu5,6Sn) and lead. The ratio of intensities of diffraction maxima illustrates the absence of a predominant growth (texture) orientation in the coating obtained through electric spark deposition. Scanning electron microscopy data prove that the surface coating layer contains melted areas, pores, spherical and oval inclusions, irregularly shaped particles, cracks, rounded pits, etc. The main reason behind melted areas deals with high temperatures developing between electrodes during an electric spark discharge. The appearance of surface fractures can be primarily associated with developing high thermal stresses and mechanical contacts between electrodes. Spherical/oval particles can develop due to interaction of liquid droplets with the cathode substrate surface. Irregularly shaped particles appear as a result of explosive emission from the edges of the erosion crater of the anode material.
利用扫描电子显微镜和 X 射线衍射仪研究了通过电火花加工在具有相似成分的阳极材料的 CuSn10Pb10 青铜表面上沉积的涂层。相组成的 X 射线研究表明存在铜锡相(Cu、α-(Cu; Sn)、Cu3Sn、ε-Cu3Sn 和 Cu5,6Sn)和铅。衍射最大值的强度比表明,通过电火花沉积获得的涂层不存在主要的生长(纹理)方向。扫描电子显微镜数据证明,表面涂层包含熔化区、气孔、球形和椭圆形夹杂物、形状不规则的颗粒、裂纹、圆形凹坑等。熔化区域的主要原因是电火花放电时电极之间产生的高温。表面裂纹的出现主要与电极之间产生的高热应力和机械接触有关。由于液滴与阴极基板表面的相互作用,会产生球形/椭圆形颗粒。由于阳极材料侵蚀坑边缘的爆炸发射,会出现不规则形状的颗粒。
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.
