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 ...
