Lubricating technology is an effective solution to avoid the wear of materials.
Self-repairing technology for wear of materials is an innovation technology in the field of surface engineering [1-5].
In this paper, a special kind of inorganic mineral powders was selected as the self-repairing materials.
The morphologies, element distributions and micro-mechanical properties of the worn surface were investigated by means of scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and nanoindentation tester, respectively. 2 Experimental 2.1 Experimental Materials The base treatment solution is 50CC oil, the self-repairing material is inorganic mineral powders.

Introduction The stress concentration problems are encountered frequently where a sudden change of geometric dimension or material property takes place in the engineering structures.
This is because the actual materials have their own microstructure and intrinsic length scale, and the steep strain gradient may occur where stress concentration occurs.
Material parameters used are: elastic modulus E=, poisson's ratio .

CTS has a highly reactive amino group is a useful material for various purposes such as ion-exchange [2].
Recently, CTS derivative bearing β-CD has received considerable attention because its adsorption behavior is different from those of natural CD and CTS materials [3, 4].
Experiment Section A.Preparation of Chemical Modification of β-CD-g-CTS Unless otherwise noted, all of the raw materials were analytical purity and used as received without further purification.

Reinforced concrete is the current main material to build liquid-storage structure.
Although the geometric and material non-linear factors were considered, but the structural integrity of liquid-storage was ignored, so that the conclusions have no universal.
