Abstract

The main goal of De_Amatech Eureka project is to develop new actuators and new materials, a^s well as technology, for the production of piston valves with much better dynamic properties and lesser energy consumption as compared to the traditional ones made of metals [1]. In this work we report the results of our investigation on model systems advanced material/surface coating. Several types of advanced materials have been developed and tested for manufacturing of parts for pneumatic and hydraulic valves, and theil' basic mechanical properties have been determined. Attempts have been made to use FTIR and micro-Raman spectroscopy for characterization of these systems aimed for the productioir of the alternative materials for piston valves. PVD magnetron sputtering metal targets were used in order to find best solution for the application of an appropriate thin coating on the sudace of the samples. Characterization of the abrasion resistance of the coated samples was perfotmed using internal methods developed by EUREKA partners. Testing of the surface microhardness of the coated materials was performed in order to evaluate the quality of the coatings.
