The Effect of SiC_p Addition on Corrosion and Wear Behavior of Conventionally and Microwave Sintered PM 316L

Abstract

In this study, corrosion and wear behaviors of PM 316L matrix composite materials reinforced with SiC particles in amounts of 10 vol% are evaluated. The samples are uniaxially cold pressed, and then sintered by two different methods, conventional sintering and microwave sintering. Corrosion properties are evaluated by both immersion and cyclic polarization tests. Wear properties are evaluated by dry sliding wear tests. Brinell and Vickers microhardness tests are applied, in order to support the wear test results. The results show that 10 vol% SiC p reinforced composite samples have acceptable corrosion properties and improved wear resistence in a similar manner, as they show good mechanical properties. In addition, microwave sintering results in better wear properties compared to conventional method.

Microstructure, interfacial characteristics, and wear performances of Cu–Fe–SiC cermet composites

“…Compared with traditional sintering, microwave sintering has complex heating equipment and high cost. Ertugrul et al 19 found in his study that the hardness, wear volume, and friction coefficient of conventional sintered and microwave sintered samples were very similar. Shabani et al 20 tested the grinding performance of the prepared Cu/SiC composites by dry sliding wear test and the results showed that, compared with the traditional sintering process, the compressive stress applied in the sintering process increased the density, hardness, and wear of sintered materials.…”

Role of particle size in microwave processing of metallic material systems

“…Latter, it was demonstrated by many researchers that the metallic powders couple with microwaves well due to higher surface area and offer rapid heating of green compacts as compared to conventional sintering [12,13]. Currently, microwave processing of the metallic materials is gaining fast popularity and microwave-based processes like heating [15–24], melting [25–28], casting [29–34], sintering [35–61], joining [62–71], and coating/cladding [72…”
