Due to complex operation conditions, the material of pump shaft should possess proper microstructure and good mechanical properties.
It can be seen that there is no Mn and overlow Cr in the material that doesn’t qualified with the relative standard.
Discussions In view of the material, neither chemical composition nor mechanical properties accord with relative standards, so the material was assumed to be misused.

CNTs have great potential for use as many different functional materials.
In a previous work, we developed a CNT-composite paper as a new functional material.
A potential solution to this problem is the development of a composite material that contains a CNT.
