The possibility of evaluating the strength of pearlite gray cast iron with lamellar graphite using the ratio of the area of the interdendritic eutectic phase to the perimeter of the primary austenite dendritic crystals was investigated. It is found that this parameter increases from 15,1 to 39,3 as the ultimate tensile strength of cast iron decreases from 300 to 180 MPa. The correlation coefficient for this relationship was 0.9.

Cavitation Erosion Resistance

The paper presents the cavitation stand used, the work methodology, the trials realized on specimens of gray cast irons, with flake graphite and spheroidal-graphite, which were tested for cavitation erosion during different periods of time of the cavitation attack. Finally, the conclusions were interpreted on the basis of comparative graphics realized at the macro and microstructures level obtained for these two types of cast iron. Of the two types of gray cast iron, the nodular cast iron presents a better cavitation erosion resistance.

Abstract After pointing out the interrelation between corrosion resistance, caustic embrittlement, fatigue, creep, and other phenomena of metals, the author cites the results of experiments on glass and quartz rods, subjected to high liquid pressures, as indicative of the action which probably occurs in cavitation erosion. To demonstrate the mechanism of cavitation on this basis, an investigation was conducted, in which tests were made on gray-cast-iron specimens in water, alcohol, glycerin, and paraffin oil, using a magnetostriction oscillator as the source of energy. The results of the tests which are reported bear out the theory. Materials and protective coatings which reduce cavitation erosion greatly, and the effect of the presence of hydrogen in the liquid are discussed.
