https://apps.webofknowledge.com/ ... age=1&doc=1 Characteristics and removal mechanism in laser cutting of cBN-WC-10Co composites 作者:Mao, C (Mao, Cong)[ 1,2 ] ; Sun, XL (Sun, Xiaoli)[ 1 ] ; Huang, H (Huang, Han)[ 2 ] ; Kang, CW (Kang, Chengwei)[ 2 ] ; Zhang, MJ (Zhang, Mingjun)[ 1 ] ; Wu, YQ (Wu, Yueqin)[ 2 ] JOURNAL OF MATERIALS PROCESSING TECHNOLOGY 卷: 230 页: 42-49 DOI: 10.1016/j.jmatprotec.2015.11.014 出版年: APR 2016 查看期刊信息 JOURNAL OF MATERIALS PROCESSING TECHNOLOGY 出版商 ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND ISSN: 0924-0136 研究领域 Engineering Materials Science 摘要 Laser cutting of a cBN-WC-10Co composite material was carried out using a pulsed Nd: YAG laser. The cutting characteristics, as well as the changes in microstructure and mechanical property, were investigated. It was found that cracks were induced by laser machining on the sub-surface and the evidence of phase transformation from cBN to hBN was observed on the cut surface. Cutting parameters had significant effect on the cut surface. A higher laser power produced a smoother cut surface, but a larger heat-affected zone, in comparison to the lower laser power used. No radical cracks were found on the cross-section at the laser power of 100W. The surface roughness and the heat-affected zone depth decreased with the increased cutting speed and the gas pressure. The material removal involved in the laser cutting of cBN-WC-Co composite was attributed to the melting or evaporation of cBN and WC-Co. The dropping of cBN particles from the cut surface was also found during the cutting at the laser power of 30W for the loss of the supporting from the WC-Co matrix. (C) 2015 Elsevier B.V.
