Abstract.
Alfalfa is the most important raw material plant to extract leaves protein. 2750-3805Kg protein can be extracted from a hectare of alfalfa’s stems and leaves, which is 1.8 times than that of soybean.
Experimental Materials Alfalfa protein, self made in the lab, Sodium hydroxide, AR, Nanjing Chemical Reagent company.
It may be caused by the impurity of alfalfa protein or the existence of a melting range of the protein as one kind of polymer material.

Using ANSYS finite element analysis software, this paper established the axisymmetric section of the W-type metallic sealing ring finite element model, using the MOGA optimization algorithm (multi-objective genetic algorithm) to optimize the structure parameters of W-type metallic sealing ring.

Morphological Analysis
The base material is Ti-6Al-4V (TC4) plate.
Coating materials are ZrO2 (containing about 7.5% Y2O3) and HA, both of them are mechanically mixed at a mass ratio of HA (70 wt.%) and ZrO2 (30 wt.%),and then sprayed to the samples by DH1080 plasma spraying equipment, with coating thicknesses 0.2mm.
Some coating materials are taken away as the asperity peaks breaks, causing the coating material peeling off microscopically and cracks at the same time.The destruction of the texture morphology is caused, as shown in Fig. 5 (d).
