Investigation of the Production and Mechanical Properties of Silicon Carbide-Reinforced Composites

Abstract

In this study, it was aimed to produce an intermetallic with low energy cost and better mechanical and physical properties with the microwave sintering method. Cupper matrix composites containing 4,8,12,16, and 20%SiC were fabricated by microwave furnace sintering at 1000°C, 1050°C, and 1100°C temperatures. Compounds formation between Cu–%10Cr and SiC powders was observed after sintering under Argon atmosphere. XRD, Scanning Electron Microscope, mechanical testing, and measurements were employed to characterize the properties of Cu + %10Cr ++4%SiC, Cu + %10Cr +8%SiC, Cu + %10Cr +12%SiC, Cu + %10Cr +16%SiC, and Cu + %10Cr +20%SiC composite specimens. The results of the test data applied to the samples were examined. For composite samples of Cu + 10% + 4% SiC composition at 1000 ° C, the hardness value was measured as 128 HV. The ceramic additive was made to increase the wear and corrosion resistance of the intermetallics.

Abstract

Bu çalışmada, mikrodalga sinterleme tekniği kullanılarak daha düşük enerji maliyeti ve iyi mekaniksel ve fiziksel özellikler elde edilmesi amaçlanmıştır. Bakır matriks tozları 4,8,12,16,20%SiC katkısı yapılarak güçlendilrilmiştir. Numuneler endüstriyel mikrodalga sinterleme fırını kullanılarak 1000°C, 1050°C ve 1100°C sıcaklıklarda argon atmosferinde 1 saat sürede sinterlenmişlerdir. Üretilen numunelere Taramalı Elektron Mikroskobu, X-Ray Difraksiyonu, mekaniksel test ve ölçümler uygulanarak numuneler karakterize edilmiştir. Numunelere uygulanan test ve bulgular sonucunda 1000 °C de sinterlenen Cu + 10% + 4% SiC kompozisyonuna ait numunler daha iyi özelliklere sahip olduğu belirlenmiştir. Bu kompozisyona ait Sertlik değeri 128HV olarak ölçülmüştür. CuCr intermetaliğine SiC katkısı aşınma ve korozyon direncini arttırmıştır.
