Assessment of compacted-cementitious composites as porous restrictors for aerostatic bearings [PDF]
Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2019 Cementitious composites reinforced with silica, silicon carbide or carbon microfibres are designed, manufactured, characterised and tested as porous restrictor for aerostatic bearings. Carbon microfibres are residues obtained from the cutting process of carbon fibre-reinforced polymers. Porosity, permeability, flexural strength and

Research on TiAl Alloy Porous Metal Flow Restrictors
MATERIALS TRANSACTIONS, 2009 For the restriction application, the uniformity of pore size and connectivity of pore channels are much more important for TiAl restrictor. TiAl porous materials have expansion phenomenon during reaction sintering for the Kirkendall Effect, and the pores were generated by its partial diffusion.
