Zhang et al. [6] indicated that the addition of La2O3 could toughen the matrix, when the content of La2O3 in MoSi2 is about 0.9%, the fracture toughness increases by about 50% more than that of pure MoSi2.

Luo et al. [2] find that in the temperature range of 400 ~ 600 (oC), the chemical reaction is the major mechanism; in the range of 600 ~ 800 (oC), the in-pore diffusion is dominant; when the temperature is above 800 (oC), the boundary layer plays the most significant role.

Furthermore, besides their ability of viscosity enhancement, the WSHAP solution also shows resistance to shear and salt.[4-5] These particular rheological properties are explained by the incompatibility between hydrophilic and hydrophobic groups within the same macromolecule.[6] Owing to their original and specific rheological properties, WSHAPs are a class of prospective candidates for use in water-based polymer systems and industrial products such as paint, adhesives, cosmetics, waste-water treatment, et al.[7-9] At present, the application of commercial arcylamide based water-soluble hydrophobically associating polymer, in the field test of Bohai heavy oilfield polymer flooding has achieved remarkable effects of decreasing water cut and increasing oil production.[10] In displacement fluids, the solution rheology and thermal stability are very important.
