The use of a combustion reaction to synthesize a refractory material was first considered by Walton and Poulos [23] who produced cermet materials using termite reactions.
A wide variety of materials have been produced by this method including carbides [27,28], borides, [25-29], nitrides [30-32], intermetallics [33,34], and composite materials [35].
The AlN powder thus obtained has been tested for application as a filler for composite materials [60].

However, the gasket stress measurement which was difficult in the actual engineering site limited its application.
It is of great significance for monitoring or evaluating the joint leakage in the engineering.
The theoretical value is conservative and can be used in engineering practice.

Introduction Titanium and titanium alloy are good materials which are used as artificial joint, artificial bone, dental implants in the field of medical implants by right of its high strength, good biocompatibility and mechanical property[1-3].
From the figure we can know that the main composition of MAO film is rutile TiO2, anatase TiO2 and Ti from basic material.
Because MAO coating is the porous structure, basic material can be tested by XRD, so Ti from basic material exists.
The intensity of diffraction peak from Ti from basic material also gradually reduces.
