| Abstract | ||
| In this study the effect of silicon carbide particle (SiCp) of 50µm size reinforced to AA 2024-T3 in the percentage of 4% was investigated. Wear specimens were prepared in dimensions of 20mm*10mm according to ASTM (G99-04) from Native metal, base cast alloy and casting reinforced alloy. Microstructure was examined using optical microscope to examine the structure and hardness test also implemented to show its effect on wear resistance Adhesive wear test was carried out on all alloys at different parameters (sliding time, load and velocity). From the obtained results of wear test it was found that wear rate increased with the increasing of all the studied parameters and the reinforced alloy improved the wear resistance in the percentage of 14% while the cast alloy improved it in the percentage of 10% comparing with the native alloy that is because of the improving in hardness value achieved after adding silicon carbide. A mathematical model has been made depending on the method of least squares which helps in foretelling about the wear rate through the knowledge of time limits taken from the experimental test as a variable with fixing the other variables; also building a model with the same method by which foretelling the rate of adhesive wear through knowing the sliding speed and load. The mathematical (theoretical) results shows a great match in magnitude with wear values attained from experimental test. | ||
