“…Bardal established the wettability of SiC by molten Al-Si6Mg0.05 and Al-Si6Mg0.6 was found to be significantly improved when the SiC had been heat treated to form a thicker layer of surface silica [9]. The other researchers also mentioned that oxidation of SiC at 1000°C decreased the threshold pressure [10][11][12]. Lu et al (1999) was investigated the wear behaviour of a composite of a pure Al matrix reinforced with 20 vol% SiC particles against quenched 1045 steel.…”

“…The contact angle between a flat substrate and a drop of liquid metal can be routinely measured by the method of the sessile drop. However, this measurement is not possible when the solid is in particulate form, in which case the wetting can be studied by means of liquid metal infiltration into compacted particulate samples [10,11,[21][22][23][24][25][26][27][28][29].…”

It is well known that there are several processes to manufacture composite materials, a large part of which consist in the infiltration of a liquid (matrix) through a porous medium (reinforcement). To perform these processes, both thermodynamics (wetting) and kinetics (Navier-Stokes) must be considered if a good quality composite material is sought. Although wetting and the laws that govern it have been well known for over 200 years, dating back to the original works of Young and Laplace, this is not the case with the Navier-Stokes equation, which remains so far unsolved. Although the Navier-Stokes equation, which describes the motion of a fluid, has been solved for many particular cases, such as the motion of a fluid through a pipe, which has resulted in the well-known Poiseuille equation, or the motion of a fluid through a porous media, described by the Darcy's law (empirical law obtained by Darcy), its general solution remains one of the greatest challenges of mathematicians today. Therefore, the objective of this chapter is to present the resolution of the Navier-Stokes equation with the laws of wetting for different cases of interest in the manufacture of composite materials.

Pressurized inert nitrogen [113,116,117,122,123] or argon [115,119,121] gas is applied up to a previously determined pressure. Sometimes different atmospheres such as air [114,115,120,124], argon/hydrogen [115], and nitrogen/hydrogen [115] are used.…”

SUMMARYThis thesis was undertaken to study the wetting between granular media (alumina) and Al-Mg alloys. The objective was to develop a test method to characterize different granular alumina particles and differentiate one from the other by using the wettability concept. Two types of experimental methods were used to measure the wetting: sessile drop and infiltration methods.The sessile drop system constructed is one of the few, if not the only one, available in Canada in which the contact angle measurements can be carried out with a liquid metal drop injected directly onto the solid surface. However, the results indicated that this method is not appropriate to differentiate different granular alumina particles due to prevention, by the rough surface, of the droplets taking their proper form.Using the infiltration system, various alumina particles were tested. The data obtained from these tests were analyzed using three capillary models based on: (i) an energy balance with an average pore size, (ii) an energy balance with a pore size distribution, and (iii) a force balance with periodically changing pore radius. The two models based on the energy balance were developed especially for infiltration experiments, and the third one was taken from the literature. The results were consistent and showed that it was possible to differentiate different alumina samples with the infiltration method. The reactions taking VI place between Al-Mg alloys and different alumina particles were also investigated by using the infiltration technique. SEM and TEM analyses showed that spinel was formed independent of the experiment duration and the type of alumina particles used in the experiments at 1000 K under argon atmosphere. The theraiodynamic analysis indicated the same tendency.
