In service circumstances, the pipe system tends to suffer corrosion attack because of its stress state, corrosion environment and microstructure of the materials [5,6].
Nevertheless, the two materials may also tend to suffer corrosion attack in service environment.
Experimental Materials.
No obvious corrosion pitting could be detected on the surface of the two materials.

Materials and Methods of Research The development of the optimal composition of the alloy was carried out in the system Ag-Cr-Zr-Re (Ce, La, Y).
Due to the high flexural rigidity of the probe console and the use of needles from solid materials, NanoScan allows indentation and scratching of the surface.
The test samples of composite materials with a size of 50x20 mm were a coated substrate based on the proposed alloy.
Experimental studies were carried out on the equipment of the Common Use Center (CUC) of unique equipment "Composition, structure and properties of structural and functional materials" of the National Research Centre «Kurchatov Institute» - Central Research Institute of Structural Materials "Prometey" with the financial support of the state represented by the Ministry of Education and Science of the Russian Federation under agreement No. 14.595.21.0004.

It access to the real-time data about the products, materials and quality information using bar code identifications, RFID and other means of automated data collection.
For one thing, MES system published the detailed material requirements planning, which is listed according to BOM, on the supplier information distribution servers, which dynamic driving the supply material.
At the same time, it can tracks the state of automobile body while manages the device, material and quality.
Traditional assembly operations management is depend on labor, because there are a large number of assembly stations and parts and this is related to packing materials plan in modern assembly shop.
