A computerized tribology information system designed for use with personal computers and including a numeric database is presently under development. The status of this system (named ACTIS) is summarized. Two important issues associated with the numeric database component were the data format and the organization of numeric data for user applications. Based on information developed at a National Institute of Standards and Technology (NIST) workshop on tribology information, a set of data fields has been identified for use in a database on friction and wear of materials, and on material properties. Evaluated data in these categories have been assembled and loaded into that format using commercial database management software. Over 360 records are presently contained in the database covering a broad range of materials of tribological significance. The data are organized for direct application by the user in material selection, wear model calculations, tribological component design, and with other software codes such as stress and temperature calculations.
