thermal spray coatings of highly reinforced Aluminium matrix composites with sol gel silica coated sic particles
Surface & Coatings Technology, 2007Co-Authors: B Torres, Marcelo Campo, Alejandro Ureña, Joaquin RamsAbstract:Abstract Low porosity coatings made of Aluminium matrix composites reinforced with SiC particles were fabricated by a thermal spray method. The initial spray material used was a mixture of Aluminium Powder and SiC particles which were directly fed in the thermal spray gun flame without any previous sintering. Sol–gel silica coatings with different structural characteristics were deposited on the SiC particles before mixing with Aluminium Powder to increase the wettability of reinforcement by molten Aluminium during the spray while avoiding the appearance of any degrading reaction between Aluminium and SiC particles. The thermal spray coatings were manufactured with different reinforcement degrees from 4 vol.% to 47 vol.% SiC using mixtures of sol–gel coated SiC particles in the 20% to 70% range. Porosity was in most cases below 1%. The relevance of using sol–gel coatings on reinforcement particles and of the sol–gel structure is analysed.

influence of water and Aluminium Powder content on the properties of waste containing geopolymer foams
Ceramics International, 2018Co-Authors: Rui M Novais, G Ascensao, N M Ferreira, M P Seabra, J A LabrinchaAbstract:Abstract The production of low thermal conductivity geopolymers has attracted increasing attention over the past years due to their low cost and green processing technology. In this work, light and porous geopolymers were produced by the proper association of Aluminium content and solid-to-liquid ratio. This allowed the production of very low thermal conductivity geopolymers (78.6 mW/m K) exhibiting homogeneous pore size distribution which suggests their use in thermal insulating applications. Moreover this study also reduced the existing knowledge gap concerning the fresh-state characterization of foamed geopolymer slurries. The influence of Aluminium Powder, curing temperature and solid-to-liquid ratio on the calorimetric response of biomass fly ash-containing geopolymer slurries was evaluated. The calorimetric response of geopolymer slurries shows that the time needed to reach the maximum temperature decreases when the Aluminium Powder rises, thus shortening the open time before in situ application. It was also found that the geopolymerization rate is governed by the curing temperature.
