摘要

摘要研究了用激光切割厚度为 6 mm 的 40Kh 钢板齿轮毛坯时，切口边缘附近区域的结构特征和显微硬度。结果表明了激光切割与表面硬化相结合的可能性。平均而言，切割不同部分的硬化表面层厚度约为 150-250 μm，最大硬度约为 46-58 HRC，这与大多数表面处理的 40Kh 钢硬化程度相当。

Formation of Hardened Surface Layer during Laser Cutting of Gears of Tooth Gears Made of Structural Alloy Steel Grade 40Kh

Abstract—The structural features and microhardness in the zone adjacent to the edges of the cut during laser cutting of gear blanks from a sheet of 40Kh steel 6 mm thick were studied. The possibility of combining laser cutting with surface hardening is shown. On average, the hardened surface layer in different sections of the cut has a thickness on the order of 150–250 μm with a maximum hardness approximately equivalent to 46–58 HRC, which is quite comparable to the hardening of 40Kh steel with most surface treatments.

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.
