<正>Al2O3/TiAl composites were fabricated by PAXD (pressure-assisted exothermic dispersion) method. The effects of Nb2O5 content on the microstructure and mecha
Al-base surface self-lubricating composites need thick and hard alumina membranes with large pores to add lubricants easily. This kind of porous alumina layer w
Firstly, an aluminum coating was produced metallurgically on mild steel by hot-dipping, then an aluminum oxide coating was formed self-growingly from the alumin
