Highway engineering slope ecological protection is to keep the ecological balance, therefore it has the engineering protection and other protection type irreplaceable role and status.
It will be sure to promote highway engineering slope ecological protection[4].
Slope ecological protection technology mechanism Ecological slope protection technology is based on the ecological engineering, engineering mechanics, hydraulics, botanical subjects etc. basic principles, using active vegetation material, combined with other engineering materials in the slope with ecological function protection system construction.
Through ecological engineering, self organization, self supporting and self repair function to achieve the slope erosion resistance, resistance to sliding and ecological restoration, so as to reduce water and soil loss, ecological diversity and ecological balance and environment beautification purposes.

Ning Shen [10] and his team analyzed the microstructural changes in the two-step aging process of 6082 aluminum alloy by DSC analysis and SEM analysis, It is found that the first stage aging in a short time can advance the exothermic peak of the β'' strengthening phase, which is favorable for the second stage aging to reach the peak state in a shorter time.
As can be seen from the DSC analysis [13], the first stage aging can cause the exothermic peak of the precipitated β'' strengthening phase to be advanced, which is beneficial to the second stage aging to reach the peak of the strength in a shorter time, thus shortening the overall aging time.

The powder material used in the flame spray is an advanced ceramic.
The advanced ceramic developed by the researchers has the properties of high heat resistance, corrosion resistance, and suitable dielectric constant, namely Yttria-stabilized Zirconia (YSZ).
YSZ is an advanced ceramic containing 7-8% wt yttrium oxide; YSZ shows good temperature resistance up to 1200oC[7].
Experimental Coating Preparation The YSZ powder (Inframat Advanced Material, USA) used contained 8% Y2O3, which was used as TC and YSZ/Al2O3 composite material with a particle size of 70.4 µm.
