Modern methods to retrieve innovative material solutions for tribosystems
A numerical, tribological data collection system with 12,100 data records was developed to find materials for tribological operations. The databse enables the user to search, retrieve and display information and data about the appropriate material couples in a fast and conventient way. The database is intended to be used by researchers, engineers, consultants and developers. All tribological characteristics of the listed materials are directly comparable; the data has been compiled and put into a standardized form, which covers the specific properties of nearly all tribometers used. The structure and the precisely defined formats may help guide future scientists and engineers to organize, archive and publish their tribological tests and results in a complete and comprehensive way.

Knowledge-based expert systems in surface coating and treatment selection for wear reduction
Abstract Most engineering failures occur because of surface initiated effects such as wear, corrosion and fatigue. Surface coatings and treatments specified at the design stage thus offer considerable potential to prevent failure and reduce costs. However, few design engineers possess the comprehensive knowledge needed to specify optimum surface coatings and there is no recognised procedure for selection which can be universally adopted. With the advent of computer systems which can manipulate and store large amounts of data at low cost, a solution to this problem is now at hand. We report the development of a knowledge-based computer system to aid the designer in this crucial area. The paper presents the methodology behind the coating/treatment selection process, and outlines the knowledge used at the various solution stages, emphasizing wear reduction. The main selection criteria are presented and the industrial application of the system is discussed.
