Abstract
The experimental results on ablation of steel targets by a scanning beam of nanosecond pulsed laser radiation are reported. The power density dependences of the ablation depth and energy efficiency in the power density range of q = 2 × 108–7 × 108 W/cm2 are determined. It is established that, under irradiation of carbon steel targets during ablation, the explosive boiling (phase explosion) mechanism is implemented, which is characterized using the introduced concept of explosion force Pe. The values of Pe determined from the published data for different materials are presented. The dependence of the ablation depth on the interval between pulses is established and the physical processes causing the ablation course are discussed.
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.
