Quality and characteristics of a material are important factor for successful manufacturing. Quality control of the material at the beginning of a production process is usually based on mechanical characteristics control and rarely on identification of structure and chemical composition. Measurement of tribological characteristics of materials (anti-frictional and anti-wear) and their abrasive resistance is still not performed in our country. This paper presents the results of tribological properties assesment of specific group of materials [2].
Scrack test consists in the application of a special device that allows increasing the load force by changing the sample carrier at a constant speed. In doing so, a diagrammatic dependence of the load forces-friction forces is formed. Tribometarblock on study was sucesfuly done. Electrical discharge machining (EDM) is a material removal procedure which can be used to machine all electro conductive materials regardless on their physical-metalurgical properties. But not all electro conductive materials are machined equally efficiently so each of them has its own characteristic EDM machinability. As an indicator can be taken different criteria such as: erosion speed, quality of machined surface, wear of electrode-part, specific energy consumption etc.
