Based on the friction,the commonly principles of abrasive wear,employing requirements and applying areas are described,so the theory foundation are provided for establishing the abrasive wear resistance material database.Modern database technologies and their applyings in the fields of material and engineer are introduced,which provide the technology sustaining and direction for establishing the database.From the non-equilibrium system and thermodynamics of irreversible process,the natures of openness,complexity and far-from equilibrium are characterized.Combined with the analysis of negative entropy flow,the characteristics of irreversibility,dissipative property,and possibility of the dissipative structure and main types are concluded in abrasive wear process of material,including the non-linear response of abrasive wear resistance material on outer actions and the variation of material degeneration or material evolution.Based on the above, abrasive wear working system(AWWS)and abrasive wear resistance material database system(AWRMDS)with multiple functions are built.This database system is created by Delphi software on the basis of AWWS.The user can input,store,inquire and print the data of abrasive wear resistance materials by AWRMDS.The system can also aid the user to manage and select abrasive wear resistance materials effectively.Based on the AWRMDS,some aspects are extension,at the same time,based on how to select and use materials in a scientific and reasoning way,selection principles of engineering materials and modern materials selection system are specialized.At last, based on this database system,a selection and estimation system of engineering materials are founded.
