The protection of the materials from HTC is a key issue.
High temperature oxidation seems to be so complicated for engineers to understand and protect materials from HTO.
He has been invited to give lectures from major scientific congresses such as Gordon Research Conference on HTC, International Symposium on HT Corrosion and Protection of Materials (the Embiez Congress) and so on.
As a result of the research works, he produced more than 180 papers in scientific journals and proceedings (163 articles referenced "Web of Science", h-index = 23) and more than 50 invited lectures.
He won the “Ugine-René Castro Prize” from the French Society for Metallurgy and Materials in 2005, and the “Grande Médaille” from the French Centre of Anticorrosion in 2010.

Research on Optimal Process Parameter Database Experiments determine some ordinary clothing materials on the market, including cotton, linen, silk, wool, artificial fiber, leather, jeans etc.
Database of optimal cutting parameters is formed after testing on these materials.
According to the cutting samples, this set of parameters optimal ones for laser cutting silk materials.
Experiments have been conducted on different cutting clothing materials as well as laser power and cutting speed parameters setting in different operating conditions.
