Finite element modelling and development of SiC-filled ZA-27 alloy composites in erosive wear environment: a comparative analysis

Abstract

The erosion wear resistance of silicon carbide (SiC) filled Zn–Al alloys is determined insolid particle erosive wear test rig under five different operation conditions such as impact velocity, SiC content, erodent temperature, impingement angle, and erodent size. This study evaluates the influence of independent parameters on erosive wear behaviour of composites. A design of experiments L16 orthogonal array design is conducted in a controlled way and a regression model is developed in order to verify the experimental results. This article tries to develop finite element simulation model (ANSYS/AUTODYN) to validate the experimental results. The results obtained in this study enable the influence and significance of various parameters to be better understood. It is observed SiC-reinforced ZA-27 alloy composites exhibit better erosion resistance as compared with ZA-27 alloy composite. In this investigation, the physical and mechanical properties of all the filled and unfilled composites are also evaluated for structural applications.

Solid particle erosion of composite materials: A critical review

“…It has not been clarified how such combinations of a matrix material and a filler material affect the erosion characteristics of MMCs and CMCs. There has been no solid particle erosion data on newly developed advanced composite materials such as carbon based nano-reinforcements, CNTs, graphenes, and so on. Simulations studies on solid particle erosion of composites have been not yet enough done. 87, 119, 186–188 Further studies will be needed to quantitative simulations.…”

“…Mamatha et al. 119 performed solid particle erosion experiments of Zn-Al alloy reinforced by SiC particles (SiC/Zn-Al), and finite element simulations of erosion characteristics of the composites to validate experimental results. It was observed that the SiC/Zn-Al composites exhibited the better erosion resistance than unreinforced Zn-Al alloy.…”

Fabrication of 6061 aluminum alloy reinforced with Si3N4/n-Gr and its wear performance optimization using integrated RSM-GA

“…Table 2 gives the characteristics of both powders utilized in this research work. SiC has been used as reinforcement by different researchers (Izciler and Muratoglu 2003;Mamatha et al 2011). Si3N4 presents a higher hardness than SiC, due to which a harder casting is obtained.…”
