• Cleavage cracking of ductile-metal substrates induced by brittle coating fracture 

      Guo, Tao; Chen, Yanmeng; Cao, Ruohan; Pang, Xiaolu; He, Jianying; qiao, lijie (Journal article; Peer reviewed, 2018)
      Brittle coatings are often used to protect underlying ductile substrates from damage. Recent experimental observations show that the fracture of a brittle coating can cause the micro-cracking of the ductile metal substrates, ...
    • Discontinuous cracking of TiN films on a steel substrate induced by an adhesive interlayer 

      Guo, Tao; Pang, Xiaolu; He, Jianying; qiao, lijie (Journal article; Peer reviewed, 2019)
      The basic mechanisms governing the process of cracking of single-layer brittle films have been extensively explored through both simulations and experiments. However, the role that an adhesive interlayer plays in the ...
    • High temperature brittle film adhesion measured from annealing-induced circular blisters 

      Guo, Tao; He, Jianying; Pang, Xiaolu; Volinsky, Alex; Su, Yanjing; qiao, lijie (Journal article; Peer reviewed, 2017)
      Testing high temperature brittle film adhesion is necessary for understanding interfacial failure at elevated temperatures. However, current brittle film adhesion measurement methods are limited to room temperature. ...
    • Substrate slip steps promote cracking and buckling of thin brittle film 

      Guo, Tao; Pang, Xiaolu; He, Jianying; Zhang, Zhiliang; qiao, lijie (Journal article; Peer reviewed, 2019)
      Cracking and buckling are the two major failure phenomena of brittle film/metal substrate structures. Herein, by depositing titanium nitride brittle films with strong and poor adhesion on stainless steel substrates, we ...
