INTRODUCTION Several methods have been developed to synthesize nano-crystalline materials; among which, inert gas condensation, electro-deposition, crystallization from amorphous material, severe plastic deformation, and mechanical milling (MM) are the most commonly used techniques [1].

Used for bond- breaking, its solid content was no less than 25%, with the mass ratio of polymer materials to paraffin being 1:2 and a qualified film-forming property.
For EASS with solid content no less than 25% and the mass ratio of polymer materials to paraffin being 1:2, the application rate for spraying was specified to be 0.4 L / m2 and no less than 0.3L / m2 as the minimal.

Meanwhile, the contact between two materials and the initial ground stress of dam foundation is considered in whole solution process, and the true behaviors are well simulated by this model.
The contact elements between two kinds of materials unity have been set on the places which have a big difference in value of cohesion, for example, dam abutments and bed rock, seepage prevention wall and dam foundation and so on, so as to simulate the contact behaviors.

Nanoparticles have different surface effects than microporous materials or other materials, for three reasons (a) dispersed nanoparticles have a very large surface area with a high number of particles per unit mass, (b) the fraction of atoms on the nanoparticle surface increases, and (c) atoms located on the surface of nanomaterials increases.
The use of chitin can be expanded when it is converted into chitin nanoparticles (ChNP) so that it has an increased surface area both in solution and in bulk materials [8].
Chitin nanoparticles (ChNP) are biopolymers that can increase the effectiveness and stability in the process of using them as raw materials for making a product and have a uniform rod-like morphology and have a low aspect ratio [10].
In large body of research showed that chitin-based glass adhesives have been developed and have good potential as raw materials for glass adhesives.
Experimental Material.

At the same time, the most important task is to develop strategic directions for the development of materials.
As a result, in this situation, increased attention is paid to the possibility of creating fundamentally new materials with a given level of properties and the development of strengthening technologies for the surface layer of products from known metal alloys.
Formulation of the Problem Generally Many industries of mechanical engineering are characterized by high energy intensity, complex operating conditions of machines against the background of constantly growing requirements for cost-effective use of materials and environmental compliance.
