Fig.5 Sketch of microhardness testing points Fig. 6 show that the hardness of each specimen increases along height direction which is basically consistent with the gradient materials design[14].But,it can be seen from each contour line that hardness distribution fluctuates wildly without ultrasonic vibration.
(1) Ultrasonic vibration will help to suppress the formation of pore and reduce its size； (2) By analysing the microstructure of middle cladding layers, it can be found that the grain size is refined for ultrasonic vibration breaking the longer dendrite;Furthermore,in the FGMs specimens, reinforced phase TiC particle size is smaller and get more uniformity distribution; (3) The microhardness tests indicate that gradient materials specimens have good hardness consistency and high mechanical property, which show the ultrasonic vibration can refine the cladding layers and homogenize the microstructure，and then improve its mechanical property.

Experimental Materials The raw materials for preparation inorganic adhesive were dead burned magnesia, fly ash (FA) and phosphates.
The concrete materials mixture proportion was Portland cement:water:sand:aggregate in 1:0.48:2:2.8.
In order to select the best materials mixture of phosphate binder, extensive tests were carried out.
Finally, three best materials mixtures among the tests were confirmed, namely P1, P2 and P3 respectively.

The principal shortcomings associated with MEMS are related to the inability of this technology to produce arbitrary three-dimensional features in not only electronics but also in a wide range of metallic materials.
The Material of workpiece is aluminum, and the micro end-mill has 100µm nominal diameter, 10° helix angle.
