Purpose: of the project was evaluation of the effect of heat treatment and of the reinforcing Al2O3 particles in the EN AW-AlCu4Mg1(A) aluminium alloy on the mechanical properties, abrasive and corrosion resistance in the NaCl water solution environment. Design/methodology/approach: some of the composite materials were hyperquenched for 0.5 h at the temperature of 495 degrees centigrade with the subsequent cooling in water, and were quench aged next for 6 h at 200 degrees centigrade. Hardness tests were made on HAUSER hardness tester with the Vickers method at 10 N. Static compression and tensile tests of the fabricated composite materials were made on the ZWICK 100 type testing machine at room temperature. Abrasion resistance wear tests were carried out with the constant number of cycles of 5000 (120 m) at various loads: 4, 5, 6, 7, and 8 N. Test pieces were rinsed in the ultrasonic washer to clean them and next weighed on the analytical balance with the accuracy of 0.0001 g to check the mass loss. Corrosion tests were made in 5% water NaCl solution. Findings: Besides visible improvement of mechanical properties: hardness, compression strength and tensile strength, wear resistance there were also observed the influence of heat treatment on the corrosion resistance of composite materials in 3% NaCl solution. Practical implications: Tested composite materials can be applicate among the others in automotive industry but it requires additional researches. Originality/value: It was demonstrated that the mechanical properties, as well as the wear and corrosion resistance of the sintered composite materials with the EN AW-Al Cu4Mg1(A) alloy matrix may be formed by the dispersion hardening with the Al2O3 particles in various portions and by the precipitation hardening of the matrix.
