Study on picosecond pulse laser ablation of
Nov 15, 2016 · It is known, since Cr12MoV contains carbides phase which have differences in optical and physical properties with main substrate, it is challenging to obtain a uniform ablated surface morphology. Therefore, it is necessary and important for the comprehensive studies on the laser ablation rate and quality of cold work mold steel, attributing to sp.info High-Strength Low-Alloy Steels - ASM designed to meet specific mechanical properties rather than a chemical composition (HSLA steels have yield strengths greater than 275 MPa, or 40 ksi). The chemical composition of a specific HSLA steel may vary for different product thicknesses to sp.info steel Composition, Properties, Types, Grades, & Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world鈥檚 infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.sp.info Effects of picosecond laser repetition rate on Jul 01, 2017 · In this paper, the effects of pulse repetition rate on ablation efficiency and quality of Cr12MoV cold work mold steel have been studied using a picosecond (ps) pulse Nd:YVO 4 laser system at 位= 1064 nm. The experimental results of area ablation on target surface reveal that laser repetition rate plays a significant role in controlling ablation efficiency and quality.
