Zirconia Coating Cracks for Gas Tunnel Plasma Spray Coating Technology

摘要

As shown the fracture problem of zirconia coating is very complicated problem. It has different phenomena than other materials and composites for many views. It needs very special method of analysis. The fracture directions and fracture loads has different types regarding the local and global analysis. The fracture increment length can be estimated as the length of the side length of the zirconia particles. Then, the fracture properties, fracture energy and fracture path can be calculated and pre-predicted by the applied theory. The safe life time can be estimated. The fracture can be controlled and may be prevented. The next step of the research will concentrate on more specific study of the fracture analysis for theses reasons.
