ANALYSIS OF ELASTICITY MODULUS AND MICROHARDNESS OF ENGINE PISTON SURFACE LAYERS IN THE ASPECT OF ITS WEAR
Journal Title: Tribologia - Year 2013, Vol 251, Issue 5
Abstract
The paper presents the results of micro-hardness and Young's modulus measurements of the surface layers of selected surfaces of engine piston. Indentations were performed in the side, bottom, and the hub of the piston, in the aspect of the wear determination. The methodology of testing and studied objects, a piston made of aluminium alloy, 80,0 mm diameter, were characterized. The indentation results, as characteristic load P vs. penetration depth h curves, which were done into the selected piston surfaces were given. The mean values and standard deviations of Young's modulus E and microhardness as a function of normal force Pmax were compared.
