This paper describes the slurry erosion of a range of HVOF deposited aluminium-based claddings on steel by sand in water. Coatings, approximately 300μm thick, of commercially pure aluminium, eutectic aluminium/silicon alloy (12%) and of a novel composite incorporating alumina in this alloy have been tested, both as sprayed and as ground to remove surface roughness as far as possible. Angular silica...
The overall objective of the study is to improve our current understanding regarding to the influence of microstructural properties on wear behavior of ceramic–metal composites.In this study the effect of microstructure variables on wear of multiphase materials is analyzed with reference to WC-, TiC-, and Cr 3 C 2 -based ceramic–metal composites (so called cermets). These variables...
Solid particle erosion of a composite material of polyetheretherketone (PEEK) matrix and unidirectional (AS4) carbon fiber was investigated experimentally. Erosion tests were conducted with 10μm Arizona road dust and 100μm sieved runway sand particles in especially designed erosion tunnel at temperature up to 260°C (500°F) and impact velocities up to 152.4m/s (500ft/s). Experimental results are presented...
