M.Wismans[1] discuss various head injury criteria based on translational accelerations of the head’s centre of gravity and injury criterion based on stress and strains inside the brain.
The criterion used while testing of the helmet is Maximum acceleration induced at the centre of gravity of head form should be less than 275g when helmet is dropped with velocity of 7.1 m/s [4] which is the requirement based on Wayne status tolerance curve as shown in Fig.2 [1] Fig. 2 Wayne state tolerance curve Table 1.

Good corrosion performance has been assigned to these hybrid organic/inorganic thin films deposition systems [1].
From Fig.1 we can see that the corrosion potential of KH550+KH567 composite silane film is the lowest, so the corrosion tendency is the weakest.
Table 1 show the adhesion between silane film and paint film can reach grade 1 or 2, especially thin films prepared by KH567-KH550 composite silane solution, while phosphate films only reach grade 4 at the same conditions.

A commercial hot-rolled AZ31B alloy with 0.8 mm thickness was also used for comparison, chemical composition of which is listed in Table 1.
Results and Discussion Microstructures of the AZ31B and the low impurity magnesium alloys after the solution heat treatment is shown in Fig. 1.
The main difference in chemical compositions of the alloys is manganese concentration as shown in Tables. 1 and 2.
