This article discussed the key features of a newly developed national data-sharing service network of material environmental corrosion with online access. Written in Java language and based on Oracle database technology, the central database in the network was supported with two unique series of corrosion failure data, both were accumulated during long period of time. The first category of data, provided by national environment corrosion test sites, is corrosion failure data for different materials in the typical environments (atmosphere, seawater and soil). The other category is corrosion data in production environments, provided by a variety of firms.
This network system enables standardized management of environment corrosion data, effective data share process, and research & development capabilities of new products and after-sale services. Moreover this network system provides a firm base and data-service platform for the project bid, safety and service life evaluation. This article also discussed the issues including the data quality management and evaluation in the material corrosion data share process, access authority of different users, compensation of shared historical data, and finally, the related policy and law making process to protect intelligence property right of database.
