The steel/porphyrin/oxide sandwich (the exterior layer being oxide) performed best compared to every other protective film and it performed better after being scratched thanks to the oxide’s higher hardness and its better capacity to remain intact, in part because it’s thicker, when in contact with other mid to high hardness materials.

Recently, there have some interests in studying the corrosion behavior of the nanocrystalline materials due to a possible difference from corresponding traditional coarse grained materials in the corrosion resistances [4-10].
Cu–Cr alloys have a significant potential interest for practical applications as high-strength and high-thermal conductivity materials as well as for use as contact materials [12-14].

Selection of materials. 1) the shell of the draining pump is made by wilding using high-strength steel plate instead of casting using cast iron, and the type of steel material is Q345B, high-strength type 35GrMo can also be used as change from normal type 45 steel.
Material of the shell of the matched electric motor also changes to aluminum alloy.

The retaining structure was damaged; the roof material was shedding and missing.
The crack of the wood component normally had relationship with the material itself.
Since water could enter into the bottom of the wall, while some materials of the retaining wall could make chemical reaction when they met water, the retaining wall became loosing, stripping, and falling off after water erosion for a long time.

Research on Product Modeling Method for Supporting the Networked Manufacturing GuoHong Mao 1,a, Jian Pan 1,b, LanFen Lin2,c 1 Dept. of Computer Science and Software, ZheJiang University of Technology, Hangzhou, China 2Dept. of Computer Science, Zhejiang University, Hangzhou, China a mgh@zjut.edu.cn, b pj@zjut.edu.cn, c llf@zju.edu.cn Key word: Networked Manufacturing;Product Modeling;Agent Technology;Web Service Abstract.This paper introduces a new product modeling method: MAPMNM (Multi-Agent Based Product Modeling for Networked Manufacturing) based on analysing the requirements of product modeling.
Furthermore, a meta-model can continue to refine into smaller meta-models, for example, the part properties meta-model is composed of materials, heat treatment, density, specific heat, coefficient of ablation meta-models.
For example, the operation of reading material, density, specific heat, stiffness and other properties of various parts. (2) Enable Operator: It is a basic operation of extracting meta-model from the master model as the operation object, so that a certain character change occurs on meat-model. (3) Analysis Operator: It is a basic operation of making a comprehensive analysis on the meta-model extracted from the master model, based on the domain knowledge.
