Investigation of novel ceramic materials (Al2O3 and SSiC) for high-pressure pumps delivery sections

In this paper, a comparative analysis of structural materials used in the construction of high-pressure pumps delivery sections was carried out. The focus was on a comparison of the ceramic materials such as corundum (alumina, Al2O3) and silicon carbide (solid-state sintered) - SSiC with bearing alloy steel 100Cr6, that is the most common material used to make pistons and cylinders of the delivery section of common rail injection pumps. Simulations performed using the finite element method have proven that ceramic materials have a number of advantages and could therefore be an interesting substitute for materials traditionally used in this area.
