Laser absorption spectroscopy for plasma-assisted thermochemical treatment - dataset

Laser absorption spectroscopy (LAS) was applied to investigate a low pressure DC-pulsed discharge in N2-H2 gas mixtures with addition of CH4 or O2. The discharge was maintained in an industrial-scale, active screen plasma nitrocarburizing (ASPNC) reactor with a steel active screen (AS). Spectroscopic lines of CH4, NH3, HCN, CO and H2O were recorded. The dataset contains the species densities for different gas mixtures.

采用激光吸收光谱法（Laser Absorption Spectroscopy, LAS），针对添加甲烷（CH4）或氧气（O2）的氮氢混合气体体系中的低压直流脉冲放电展开研究。该放电维持于配备钢制活性屏（Active Screen, AS）的工业级活性屏等离子体渗碳氮化（Active Screen Plasma Nitrocarburizing, ASPNC）反应器中。实验记录了甲烷、氨（NH3）、氰化氢（HCN）、一氧化碳（CO）及水蒸气（H2O）的光谱谱线。本数据集包含不同气体配比下的各物种粒子数密度。
